tires, slow acceleration and going speed limit or less are the three biggest in my experience. good luck to all the TJ drivers out there! just remember its worth it.
Coming from a dad who gave up their Jeep and is now dredding it. It is definitely worth it! No car payment cheaper insurance and in CT cheaper car tax! Older Jeeps make more sense in every way to me.
It is so beautifully worth it. With modern cars you have an ugly appliance that transports you. With the last of the classic Jeeps, you have far more than transportation, you have freedom. I would easily put the Spirit of Freedom on the bonnet of my Jeep and it would be adequate. It would be more adequate than any other vehicle, including Rolls Royce. Freedom beyond any possible vehicle, including an aeroplane and boat exists only in a TJ. I am sorry, everyone, for the display of emotion.
My jeep has a Super Lift speedometer calibrator installed and it works within 1% of actual speed and miles covered. My understanding is Super Lift no longer makes this particular product but they may have something else. I would be surprised if there isn't something out there to make your speedo accurate. On earlier transmissions a simple gear change on the speedo drive cable works. On later models an electronic device is needed to correct the speedo.
And using the manual tranny properly goes a long way towards fuel economy. No one, and I mean no one, including this jeep guy, will ever convince me that an automatic gets better fuel economy than a manual.
I drive the speed limit and I know it pisses people off. Even police have told me that it's okay to go five or ten over. However, that does not work. The people behind just want to go faster than you so they will pass me at any speed I drive. I sometimes drive on a highway where most are going 85 in 55 zone. I can't do that so I just drive the speed limit and don't waste fuel.
I’m an original owner of a 1997 spec-ordered TJ Sport. I bought it, with the return of the “round eyes”, when we transferred from Virginia Beach to Rhode Island….and I wanted a dependable 4wd vehicle, to travel throughout New England….and for those numerous Navy Reserve drill weekends! All my kids learned to drive “stick” in her, and while I’ve had some ridiculous offers, I don’t have the heart to part with her. I’m right at 146k(+or-) on the clock….and I typically get 20mpg, and once in a “blue moon”, very close to 21 mpg! I did upgrade my tires to 31s…but maintained all original running gear--so no real mods to speak of --and the other thing I’m religious about, aside from the regular service schedule, is belts, hoses, flushing the system, and while mostly running 87octane, once every 4-5 fill ups, I go to either Sunoco or Mobil, and fill up with 89 or 90. I keep a record of all my maintenance this includes gasoline) and perhaps it’s the cleansers in those name-brands….perhaps it’s my imagination. But when, just every so often, I get over 20 mpg (even just so slightly), it’s worth a few fingers of a quality bourbon that evening! I may have to try that SeaFoam idea. Great video…a lot of it is common sense….but it’s worth reminding all of us to “pay attention” to the details!!! Bravo-Zulu, sir…..well done!
Thanks for taking the time to leave this comment! What an awesome story! I’m sure your Jeep is part of the family. That’s so cool to hear that you take such good care of it and that your kids learned stick on it. Appreciate the kind words as well and thanks for watching!
I found going to an electric radiator fan with a thermostat to be the best engine mod for fuel economy. Next, I found not going over 235 75R15 tires to be the biggest chassis help.
Dropping some excess weight should help. Taking off that big, heavy spare, and back seats, if not using them, will help, and increase performance. Honorable mention would be getting a lighter hood, and installing a steering stabilizer, to stop the wandering at highway speeds.
Best way to get great gas mileage from your TJ is SELL IT 😂 97 TJ 115k miles Auto AC Hard Top 4.0 33’s Long arm kit And a lot more 10mpg around town 14-15 highway I don’t care about mileage, it always puts a smile on my face when I drive it… haven’t ever had a payment on it, owned it for 19 years 😁
Driving my 3rd Jeep Wrangler now, the 2022 Old Willy's style.. All great tips especially about keeping up with the correct air pressure in the tires. I only have 2200 miles on it so far, so probably not going to try the gas additive, but maybe down the road. For me, I've learned over time to coast as often as possible.. It almost feels like it's more work for me on and off the accelerator as often as I do, BUT over the years I've been able to realize as much as 60+ extra miles on a tankful when I am committed to it. Thanks for your video!
Second owner of a 1993 Cherokee XJ Sport. 4.0L, 5-speed. 225/75R15s. No air. Crank windows. Original radio and speakers. Added new leaf springs to rear since factory ones were flat. Leveled front. Roughly a 2.5" lift. Still gets 20-22 mpg. I ignore the shift light and shift around 3000-3500 rpms.
I did a ''flow'' test on my hood to see where air moves with hood vents and a cold air intake and found there is no air movement around the windshield base so don't worry about a Highlift being there...it won't be a drag on the Jeep.
I have an '06 LJ that is mostly stock fitted. I did install ARB Bull Bumpers coz I mainly use my Jeep for rescue work in the North Carolina countryside. I removed the spare tire AND the backseat which improved my mileage to 18 mpg. Sometimes I think about upgrading to a newer Jeep but I really do need that 4.0, 6 Inline engine. I've amazed people with what I can "pull" out of hazardous situations with my Jeep.
The 4 whole fuel injectors sold on Amazon gained me around 32 miles extra per fill up. They also increase pedal response time. My 02 tj has immediate response when I hit the gas pedal. So then I started researching fuel economy an found , throttle body spacers. The spacers I installed was a nice chrome piece. Cosmeticly appealing, an added yet another 8 to 12 miles per tank and again increased response time with a bit more horse power . Nothing drastic, but noticeable! Then I replaced the 55mm throttle body, with an 300$ after market 62mm throttle body. I lost all the fuel economy an gained a whistle that was irritating as hell. So I took the 62mm throttle body off an went Back to stock throttle body. All the lost fuel economy came write back. Jeep are not made for drag racing ,lol. So food for thought. 86 $4 whole fuel injectors, and a nice 20$ chrome throttle body spacer is all I needed. Over 500$ a year in my pocket from gas savings !!
On my '97 TJ 2.5L with 31" tires I need 15L/100km (18mpg). Because of bad fuel economy AND bad performance as well, I was advised to go to gear ratio 4.88 (others say 4.11), imho default it as 3.73 Such a package is about €3.000 - and still a major improvement cannot be guaranteed...
I drive like an old man (because I am) never go over 65… use cruise control if I go over 30. 11.5 mpg best I can do… If you want excellent mileage, install a Cummins R2.8.
Two things: You can use Shell, Mobil, Costco (there are 2 or 3 others) gasoline which has very good detergents, and avoid having to buy fuel injector cleaners. Those options are pricier, but they help efficiency. I have learned to just shut down my manual TJ even before I hit a red light, and coast to a stop, then turn it back over when the light turns green. I learned from all the fancy new cars that do this by design. I just do it manually on my 5-speed manual. It takes some practice, but it's called hypermiling. Good luck Jeepsters! ✌
Hey Alexander, thanks for this comment! I would have never thought to try this, I didn’t realize that was a more efficient way to stop at a light in these older vehicles. Thanks for watching!
@@Montanaoffroad1Be very aware that the power brakes will lose pressure after you pump the brakes once and let go while the vehicle is off, so make sure you can stop in one pump of the brakes. After one pump the brakes will be much harder to pump and the Jeep much heavier to stop. Like I said, it takes practice. Good luck...
Yes the built like a brick aspect. I owned the FJ 40's in the 1970's. Three of them. One day while headed due north toward Judith Gap into a stout north wind, the brick could only make 44 mph. The fiberglass roof took the strain badly. At least Jeeps have a slightly raked windshield. I am happy with my old XJ at the moment.
Helpful info, however here in San Diego, CA regular gas is up $6.30 per gallon and currently I run 33's on my Jeep jk. Golden state current gas prices and Jeep owners don't get along 😢.
I use marvel mystery oil, 4 - 6 oz. in the tank after fill up and 5 oz. in the crankcase 500 miles before an oil change. I have 32" ko2's with 3.73 gears. I just can't justify the expense of moving up to 4.11's. Gas prices are brutal and I'm a doors and window garage storer from late April - late Oct. I like that open air experience and not letting the 260 miles I'm currently getting to a tank stop that. I don't jack rabbit off the line and keep my speed low and on cruise control to conserve fuel. My wife and I and our two sons favorite off roading is beach and dune wheelin'. Especially beach camping and surf fishing in the Outer Banks, NC. And with lowering the psi to 22 and in 4Hi, the gas mileage is worse. But the pros far outweigh the cons in the ole '05 TJ Rocky Mtn! Cool video and I'm looking to see if seafoam is better than MMO. 🤔🏖😎
Thank you for your detailed comment! 260 miles on a tank is really solid! One thing we don’t get in Montana is beach wheelin’ and camping which is something I would love to do someday! Thanks for watching!
For real I saw a slight improvement in my MPG on my Gladiator when I got my tonneau cover. It's only noticeable on extended drives on the interstate but it is noticeable.
MOA is an oil additive, makes your oil more slippery and lasts longer. EPR is a valve cleaner basically, removes carbon from inside the engine. Both BG products.
Yes, maintenance is important. If your check engine light is on the computer may be causing a rich fuel situation to protect itself. Tire pressure is more important. Big tires rolling at 30 PSI are going to use more fuel. Having a second set of wheels and tired that are for your daily driving can save enough fuel to pay for themselves. A change to the gear ratio is also going to require more spin of the engine to get the same spin of the tires. SeaFoam isn't a one and done solution, it is part of the ongoing maintenance.
7/16/2023 Tire size makes a big difference in fuel mileage. When I bought my '06 wrangler X a few weeks back [a true "hanger find". (28,000 miles on the clock)], it had 285/70R17s mounted and got 11.9 MPG. Replaced those tires with 265/70R17s and now the MPG is at 16.5. Note: there is a Super Lift speedometer/odometer calibrator mounted on the Jeep so speedo and odo are accurate with in 1%. My understanding is this product is no longer available. Am looking down the road and probably going to install 4.10s instead of the stock 3.73s. Lunchbox lockers are also a later install. Reason for the lunchbox's instead of a "Trutrak" is price including installation. I can live with the ratcheting of the lockers. See my videos on first impressions and first addons I made. At the end of one is how I checked for an open differential.
It's only like 150 lbs. It more than makes up for the weight difference with more consistent aerodynamics and a more comfortable ride. Besides, here in the U.S., 69% of adults are overweight or obese. Most people should focus on personal weight reduction to achieve the best savings. The medical bills for being obese are way more expensive than using the difference in gas between +/- 150 lbs.
Watching my speed and timing traffic lights so that I don't have to come to a stop. I cheat with the 6 speed as much as possible, shift at @ 2,000 rpm on level ground or going downhill. Not getting in a big hurry is a tremendous help for better mileage.
I have a '19 Sport S JL. Running it here in SW Montana on the freeway I average 27mpg in town 19 mpg. Mine has the 3.6L with the 8 speed tranny. I reduce weight as much as possible, meaning I don't carry anything in it unless I'm going off road.
That’s some good mileage for a Jeep! Certainly a lot better then older Jeep’s but I’m okay with that because my Jeep holds a special place in my heart lol. Thanks for watching!
With my stock 1998 TJ 4.0 5 speed with 30" tires and driving the speed limit I get 20mpg with 91 octane (no ethanol) and about 17mpg with 87 octane (10% ethanol.)
I have a 2006 Sport, 4.0L, 6 speed, 3.73s with 30 inch tires (factory optional size). I’ve learned that just keeping things as stock as possible gives you a good running, efficient vehicle. My only mods are some pod lights on a light bar in front of the grille and 30” AT tires. Shifting around 2k, not bogging it / having your foot in it, running a soft top and (dare I say) highway tires does help a whole lot. In the past on the highway I’ll get between 17.5-19.5 mpg at 65-70mph in New York (with hills) and on flat ground, country roads, long distances, at around 50 mph, it’ll make its way to 21.5 mpg. These high ratings only really happened in the spring / fall. Like stated in the video, consistent maintenance helps. Oil changes every 3k and keeping the tire pressures at manufacture specs goes a long way. I know that changing out the diff fluid on both axles, your transmission fluid and transfer case fluid (as per the owners manual) will help the cause.
I totally believe you! We do this to ourselves adding all of these aftermarket modifications but for most of us it’s worth it! Thanks for your comment Tom and thanks for watching!
Lucky us...in Europe we have the 2.8 CRD diesel, which is a modern common rail diesel developed in Italy......keep it in 'the green' and it is a really economical engine.....also has somewhere in the region of 180bhp.......If your Jeep is a 'keeper', why not consider the cummins 2.8 'crate' diesel that is designed to fit your Jeep....expensive yes but.....should you move to a different/newer Jeep?? take your engine with you.
@@Montanaoffroad1 I know, I know, (I'm a bit of a cummins fan) I'm a bit biased, and when I got my first Wrangler JK CRD, this engine was a bit new and untested in common rail guise (although it has been around decades in its old form (was even used in the Range Rover for a while). So I made plans should the engine go bad on me....6 years on and 100,000 kilometres and the engine gets better and better, so I don't have to think about going Cummins either. The new JL CRD for Europe has a 2.2 Alfa Romeo engine. (200bhp)..should rev a little then :)
On over the road and in general , I run the highest tire pressure to diminish rolling resistance. I run my Rubicon Unlimited 3.7 with 42psi and get 17 mpg with no center of tire wear , plus I rotate my spare into every tire rotation and get 50k + miles on my 30” tires. My off road is on muddy and rough job sites or on the normal South Dakota roads, which are often mud or gravel and not plowed often in the winter.
For a vehicle that historically goes off the beaten path, I’ve never understood why it has such a small tank capacity. Many extended range tanks fill the voids underneath for those who wish to purchase them. The question becomes , why doesn’t Jeep just put a 30-36gal as standard capacity. I have a friend with a Lexus suv with 16 gal tank, that is ridiculously low capacity and 21 gal for Jeep is absolutely crazy low capacity.
36 gallon?! Lol that's absolutely preposterous. Most full size pickup trucks don't hold that much. My Ram 1500 Laramie SLT with a 5.9L 360ci Magnum V8 has a 24 gallon fuel tank, and the truck is 52" longer, 12" wider, and weighs anywhere from 500-1000 lbs more. Where would all this extra fuel go exactly? You'd have to give up even more of the precious little interior/cargo space. 36 galls is madness.
Btw "filling the voids underneath" more than it already does would leave no room for the rear track bar and would make minor repairs and maintenance for the rear suspension an absolute nightmare.
I like to run a quarter tank or so with the seafoam in it and then some premium, seems to get the job done without the need for the whole bottle each time. Nuke it if its really bad tho, it generally won't hurt to run more than ya need but idk if you want to concentrate it too much. Suck some down a vacuum line let it sit and you really are in for a smoke show as it blows out the goodness. I did kill a carburetor with deep creep by over doing it instead of rebuilding it so all good things in moderation.
If you are driving locally you don’t need spare tire. Just like tesla they don’t carry. Spare tire. And this is going to make big big difference and also i thing soft top is better than hard top.
Love your vids. I laughed out loud in the beginning. Sorry if I missed it in the comments, but what do you average for MPG. Looking to buy TJ and your setup is very similar to how I’d like to run one once I get it. Great looking Jeep by the way. Thanks for your content.
With the lift and 37 inch tires i am still getting 15 to 16 miles to gallon but with the 4.88 gear upgrade i am now getting better in town miles than highway miles
I would've though lightening the load would be chief. Take off all doors, the top, put the windshield down to receive free bug dinner, riding on the stock tires (you guys did keep those before you lifted it, right?) Also was wondering about those more rare jeeps that had diesel engines, what their mpg is. Anybody out there know?
@@Montanaoffroad1 I keep forgetting traffic doesn't exist in Montana. We have highways in Indiana, but things are a lot closer to each other here than out in bug sky country.
I'd just love to be able to buy a new stock gas tank so I can fill the damn thing over a half tank without it sloshing out!!! The damn plunger hack (sanding it down) (its because of ethanol gas) didnt go as planned.. I broke the plastic cage off that houses it. 97' TJ sport.
Sorry to hear that Richard! Half a tank doesn’t get you far in a TJ! I’m sure you’ll be able to snag a new tank for it sooner or later! Thanks for watching!
It’s coming! My main takeaway is that my Jeep seems to idle smoother and but it didn’t appear to play much of a factor mileage wise. Thanks for the reminder Dan!
Hi, my best tip is you speed, on my new 2024 Jl automatic when you have in manual mode and find the setting on the dash for mileage, at different speeds the computer tells you what YOUR MPG is. My best is 90 km. Check it out. Doug 🇨🇦
Highway when I’m babying it I get about 15.5 and in town 14. Nothing crazy but like I said, no one buys a Jeep for the mileage! I still am yet to regear because I want new axles with the gears already in them. Thanks for watching!
@@DonaldChapman Hey Donald, while I feel seafoam is a good product for your vehicle I didn’t not notice a notable difference in my fuel economy. Thanks for watching!
There are quite a few cool places you can visit! Check these out, Blue mountain Jeep Trail, Leadville Jeep Trail, Thompson Lake 4x4 trail and then also join the Facebook group Montana Overland and 4x4 Adventures because there are a lot of schedules trail rides and such that you can take part in. Hope this helps!
Regarding the sea foam product. I don’t use it, but I wonder if you took the cost of the can into consideration? For example if a can goes for 32 bucks and your tank holds 15 gallons you’ve just increased the price of that tank by $2.00 a gallon. Is it worth it?
Its around 10$ not 32 for reference and you don't use a whole bottle per fill up just for a big clean out its like 1 or 2 oz per gallon if you're looking keep up on it. I usually run a quarter tank with this in it and then a full tank of premium and it does the trick. It helps now and again especially on something that's been sitting or is just old.
No way is it the outside parts. It's definitely the motor and fuel system. No way that the terrible gas mileage is caused by the tires or accessories. It's a dodge. I have a 2014 jk lifted with 35s.
Thanks for watching!

Transmission choice effect depends on the driver. Manuals still let you cheat a little bit into getting more mpg if you know what you’re doing.

Do you have the link for the injectors
On my '97 TJ 2.5L with 31" tires I need 15L/100km (18mpg).
Because of bad fuel economy AND bad performance as well, I was advised to go to gear ratio 4.88 (others say 4.11), imho default it as 3.73
Such a package is about €3.000 - and still a major improvement cannot be guaranteed...
18 mpg ain’t bad at all with your setup! Thanks for watching!
Did you have a 10 gallon tank and do a 19 gallon filler mod?
I drive like an old man (because I am) never go over 65… use cruise control if I go over 30. 11.5 mpg best I can do…
If you want excellent mileage, install a Cummins R2.8.
I've got an 04 4.0 auto, 4.56 gears, 35s w/ 4" lift. Tires at 28 psi. It's my daily at the moment due to lifters in truck. Averaging 17 mpg
Two things:
You can use Shell, Mobil, Costco (there are 2 or 3 others) gasoline which has very good detergents, and avoid having to buy fuel injector cleaners. Those options are pricier, but they help efficiency.
I have learned to just shut down my manual TJ even before I hit a red light, and coast to a stop, then turn it back over when the light turns green.

Golden state current gas prices and Jeep owners don't get along 😢.
🤢🤮 that’s awful man! I appreciated you watching though!
I may or may not have snorted in the intro - I’m watching the fuel gauge drain in real time is so relatable 🤣
Glad you enjoyed it! 😂 Thanks for watching Sam!
I use marvel mystery oil, 4 - 6 oz. in the tank after fill up and 5 oz. in the crankcase 500 miles before an oil change. I have 32" ko2's with 3.73 gears. I just can't justify the expense of moving up to 4.11's. Gas prices are brutal and I'm a doors and window garage storer from late April - late Oct. I like that open air experience and not letting the 260 miles I'm currently getting to a tank stop that. I don't jack rabbit off the line and keep my speed low and on cruise control to conserve fuel. My wife and I and our two sons favorite off roading is beach and dune wheelin'. Especially beach camping and surf fishing in the Outer Banks, NC. And with lowering the psi to 22 and in 4Hi, the gas mileage is worse. But the pros far outweigh the cons in the ole '05 TJ Rocky Mtn! Cool video and I'm looking to see if seafoam is better than MMO.
🤔🏖😎
Thank you for your detailed comment! 260 miles on a tank is really solid! One thing we don’t get in Montana is beach wheelin’ and camping which is something I would love to do someday! Thanks for watching!
It's all about SMILES / gallon.
Enjoy the brick on logs and if you want mileage get a black and decker cordless!
Seafoam was made for marine engines btw and not fuel injection variable valve timing etc etc.
Hey Elm, Seafoam is made for cars, trucks, boats, tractors, etc. says right on the front on the bottle 😂
Change your front wheel hubs to manual locking hubs an see how much more fuel you save
Thanks Tom, and thanks for watching!
For real I saw a slight improvement in my MPG on my Gladiator when I got my tonneau cover. It's only noticeable on extended drives on the interstate but it is noticeable.
BG EPR and MOA in the engine is also one of the best things you can do.
I’ll look into that!! Thanks for watching!
Add MOA to your oil changes and you will get nice bump in mpg. EPR cleans everything very well. Just did both of these to my TJ this morning actually.
I’ll try it out, thanks for the tip!
What's moa and epr?🤔
MOA is an oil additive, makes your oil more slippery and lasts longer. EPR is a valve cleaner basically, removes carbon from inside the engine. Both BG products.
You can also put it in your intake to when the motor is running to clean the motor more and you can put it in your oil it is one once per quart of oil
Yes, maintenance is important. If your check engine light is on the computer may be causing a rich fuel situation to protect itself. Tire pressure is more important. Big tires rolling at 30 PSI are going to use more fuel. Having a second set of wheels and tired that are for your daily driving can save enough fuel to pay for themselves. A change to the gear ratio is also going to require more spin of the engine to get the same spin of the tires. SeaFoam isn't a one and done solution, it is part of the ongoing maintenance.
Absolutely man! Thanks for for watching!

Tire size makes a big difference in fuel mileage. When I bought my '06 wrangler X a few weeks back [a true "hanger find". (28,000 miles on the clock)], it had 285/70R17s mounted and got 11.9 MPG. Replaced those tires with 265/70R17s and now the MPG is at 16.5.
Note: there is a Super Lift speedometer/odometer calibrator mounted on the Jeep so speedo and odo are accurate with in 1%. My understanding is this product is no longer available.
Am looking down the road and probably going to install 4.10s instead of the stock 3.73s. Lunchbox lockers are also a later install. Reason for the lunchbox's instead of a "Trutrak" is price including installation. I can live with the ratcheting of the lockers.
See my videos on first impressions and first addons I made. At the end of one is how I checked for an open differential.
Another thing to reduce gas consumption is to change the hard top for a soft top; the hard top is very heavy!!!
That’s a very good one! Thanks for watching!
It's only like 150 lbs. It more than makes up for the weight difference with more consistent aerodynamics and a more comfortable ride. Besides, here in the U.S., 69% of adults are overweight or obese. Most people should focus on personal weight reduction to achieve the best savings. The medical bills for being obese are way more expensive than using the difference in gas between +/- 150 lbs.
Watching my speed and timing traffic lights so that I don't have to come to a stop. I cheat with the 6 speed as much as possible, shift at @ 2,000 rpm on level ground or going downhill. Not getting in a big hurry is a tremendous help for better mileage.
I've got a 99 TJ, lifted, 35" tires and armor. Even at best, 16 mpg is about tops for me.
Hey Lindel, yeah I hear you, Jeep’s are never going to be the most economical vehicle but they sure are a lot of fun! Thanks for watching!
I have a '19 Sport S JL. Running it here in SW Montana on the freeway I average 27mpg in town 19 mpg. Mine has the 3.6L with the 8 speed tranny. I reduce weight as much as possible, meaning I don't carry anything in it unless I'm going off road.
That’s some good mileage for a Jeep! Certainly a lot better then older Jeep’s but I’m okay with that because my Jeep holds a special place in my heart lol. Thanks for watching!
@@Montanaoffroad1 I agree, they do hold a special place with the owners.
With my stock 1998 TJ 4.0 5 speed with 30" tires and driving the speed limit I get 20mpg with 91 octane (no ethanol) and about 17mpg with 87 octane (10% ethanol.)
That’s good mileage! The big tires really take a toll for sure. Thanks for watching!
I have a 2006 Sport, 4.0L, 6 speed, 3.73s with 30 inch tires (factory optional size). I’ve learned that just keeping things as stock as possible gives you a good running, efficient vehicle. My only mods are some pod lights on a light bar in front of the grille and 30” AT tires.
Shifting around 2k, not bogging it / having your foot in it, running a soft top and (dare I say) highway tires does help a whole lot. In the past on the highway I’ll get between 17.5-19.5 mpg at 65-70mph in New York (with hills) and on flat ground, country roads, long distances, at around 50 mph, it’ll make its way to 21.5 mpg. These high ratings only really happened in the spring / fall.
Like stated in the video, consistent maintenance helps. Oil changes every 3k and keeping the tire pressures at manufacture specs goes a long way. I know that changing out the diff fluid on both axles, your transmission fluid and transfer case fluid (as per the owners manual) will help the cause.
I totally believe you! We do this to ourselves adding all of these aftermarket modifications but for most of us it’s worth it! Thanks for your comment Tom and thanks for watching!
Great information!
Thanks, and thanks for watching!
I bought my TJ in 2016 gas was $1.79 . Ahh good times now gas is at 4.54 where I’m at . Kinda regret the 35s at this point .
Who could have known it would have gotten this crazy 🤷♂️ thanks for watching watching!
Lucky us...in Europe we have the 2.8 CRD diesel, which is a modern common rail diesel developed in Italy......keep it in 'the green' and it is a really economical engine.....also has somewhere in the region of 180bhp.......If your Jeep is a 'keeper', why not consider the cummins 2.8 'crate' diesel that is designed to fit your Jeep....expensive yes but.....should you move to a different/newer Jeep?? take your engine with you.
That’s a little out of my wheelhouse to be honest! I’ll run this motor till it dies and then worry about it! Thanks for watching!
@@Montanaoffroad1 I know, I know, (I'm a bit of a cummins fan) I'm a bit biased, and when I got my first Wrangler JK CRD, this engine was a bit new and untested in common rail guise (although it has been around decades in its old form (was even used in the Range Rover for a while). So I made plans should the engine go bad on me....6 years on and 100,000 kilometres and the engine gets better and better, so I don't have to think about going Cummins either. The new JL CRD for Europe has a 2.2 Alfa Romeo engine. (200bhp)..should rev a little then :)
I have used sea foam for years, especially in my small engines!!
On over the road and in general , I run the highest tire pressure to diminish rolling resistance. I run my Rubicon Unlimited 3.7 with 42psi and get 17 mpg with no center of tire wear , plus I rotate my spare into every tire rotation and get 50k + miles on my 30” tires. My off road is on muddy and rough job sites or on the normal South Dakota roads, which are often mud or gravel and not plowed often in the winter.
For a vehicle that historically goes off the beaten path, I’ve never understood why it has such a small tank capacity. Many extended range tanks fill the voids underneath for those who wish to purchase them. The question becomes , why doesn’t Jeep just put a 30-36gal as standard capacity. I have a friend with a Lexus suv with 16 gal tank, that is ridiculously low capacity and 21 gal for Jeep is absolutely crazy low capacity.
My TJ is rocking a 16 Gallon tank lol. I agree with you there! Thanks for watching!
Good point
36 gallon?! Lol that's absolutely preposterous. Most full size pickup trucks don't hold that much. My Ram 1500 Laramie SLT with a 5.9L 360ci Magnum V8 has a 24 gallon fuel tank, and the truck is 52" longer, 12" wider, and weighs anywhere from 500-1000 lbs more.
Where would all this extra fuel go exactly? You'd have to give up even more of the precious little interior/cargo space. 36 galls is madness.
Btw "filling the voids underneath" more than it already does would leave no room for the rear track bar and would make minor repairs and maintenance for the rear suspension an absolute nightmare.
I like to run a quarter tank or so with the seafoam in it and then some premium, seems to get the job done without the need for the whole bottle each time. Nuke it if its really bad tho, it generally won't hurt to run more than ya need but idk if you want to concentrate it too much. Suck some down a vacuum line let it sit and you really are in for a smoke show as it blows out the goodness. I did kill a carburetor with deep creep by over doing it instead of rebuilding it so all good things in moderation.
Bigger tires for high speed on the expressways
Yes this is true if you spend a lot of time highway driving. Thanks for watching!
If you are driving locally you don’t need spare tire. Just like tesla they don’t carry. Spare tire. And this is going to make big big difference and also i thing soft top is better than hard top.
Love your vids. I laughed out loud in the beginning. Sorry if I missed it in the comments, but what do you average for MPG. Looking to buy TJ and your setup is very similar to how I’d like to run one once I get it. Great looking Jeep by the way. Thanks for your content.
I have a 2006 jeep commander limited, 5.7 hemi 3” lift. I’m lucky if I get anything over 10.
And I’m sure it’s still worth it! Thanks for watching!
With the lift and 37 inch tires i am still getting 15 to 16 miles to gallon but with the 4.88 gear upgrade i am now getting better in town miles than highway miles
I did 4:88 and 35 inch and mileage stayed the same with a 4,0.
I have 35’s and just reheated to 4.88. Mpg went from 13.5 mpg to 14.5 mpg with the regear. 97 Sahara I6, 35’s, 4” lift.
Great content!!!!
I would've though lightening the load would be chief. Take off all doors, the top, put the windshield down to receive free bug dinner, riding on the stock tires (you guys did keep those before you lifted it, right?) Also was wondering about those more rare jeeps that had diesel engines, what their mpg is. Anybody out there know?
Lol not quite, especially not of the highway. I know those newer Diesels do better on gas. Thanks for watching!
@@Montanaoffroad1 I keep forgetting traffic doesn't exist in Montana. We have highways in Indiana, but things are a lot closer to each other here than out in bug sky country.
Haha! Very true, lots of open road and very little traffic.
I'd just love to be able to buy a new stock gas tank so I can fill the damn thing over a half tank without it sloshing out!!! The damn plunger hack (sanding it down) (its because of ethanol gas) didnt go as planned.. I broke the plastic cage off that houses it. 97' TJ sport.
Sorry to hear that Richard! Half a tank doesn’t get you far in a TJ! I’m sure you’ll be able to snag a new tank for it sooner or later! Thanks for watching!
Fun fact: Sea Foam was originally intended to be put in the crank about 20 to 50 miles before the oil change.
Synthetic oil in my BMW. It’s hard to even get the engine hot. It is so friction free.
People add steel bumpers, winches, tire carriers, 35" tires. That's a lot of extra weight.
Very true
When are we getting that review of the fuel additive?
It’s coming! My main takeaway is that my Jeep seems to idle smoother and but it didn’t appear to play much of a factor mileage wise. Thanks for the reminder Dan!
Lol, God can I relate to this. I was so shocked when I first got my jeep. I thought maybe something was wrong. But nope wrangler guzzles
They are quite the thirsty rigs haha, thanks for watching!
Hi, my best tip is you speed, on my new 2024 Jl automatic when you have in manual mode and find the setting on the dash for mileage, at different speeds the computer tells you what YOUR MPG is. My best is 90 km. Check it out. Doug 🇨🇦
I AM CURRENTLY GETTING ANYHERE FROM 16.7-17.0 MPG WITH MY 2011
JEEP WRANGLER JK. STANDARD RIDE HEIGHT WITH NO BODY MODS
Quality intro 😃😉
Thanks! 🙏
Just add an angry grill, air will flow better over the windshield...
Yeah there’s an extra 10 mpg minimum 🤣 thanks for watching!
Its about the smiles per gallon, not miles per gallon.
I save money on gas with my 05 LJ by driving my Tacoma :). I drive the LJ for smiles per gallon.
Fair enough! Sounds like a good way to save a few bucks 🙂 thanks for watching!
Paint the roof white. Cooling 2 square yards of black plastic by burning more gasoline is just stupid. My AC freezes me out on the first notch now!
Smaller side mirrors help .👍🏻💯🇦🇺
What size gas tank do you have in your jeep wangler TJ? I have a YJ wangler and going to put in a bigger gas tank so I can definitely go further.
16 Gallon tank. It ain’t much but I don’t have many fuel issues. Thanks for watching
I got a 15 gallon on my Jeep Wrangler YJ. When i have the money I'm definitely getting a bigger gas tank for my Jeep.
I get extra miles in my Jl with a jerry can
😂 that’ll do. Thanks for watching
I drive a '72 CJ5 with 304-V8 ... gas mileage? I give her gasoline & she goes for little while ;)
Haha I’m sure you get plenty of smile per gallon! 😁 thanks for watching!
@@Montanaoffroad1 spot on :)
Street tires and road tires if it's a daily driver
Hey Kimberlynn, this is very true if you don’t use your vehicle for off-roading or if you do it’s very mild. Thanks for watching!
Depending on the year, moving your IAT sensor off the lower portion of the intake that’s close to the engine can help.
Can i use seafoam in a manual transmission?
never use synthetic oil it is too thin and will leak all seal gaskets use what's called for. I have 2 4.0
Minute 0:38very accurate . . . 😂😂
We all know the feeling 😂
What is your MPG? I'm getting about 13.5MPG on 2003 TJ. I have a winch, hard top, 3 in lift, 33 in tires, and 4.10 gears...considering going to 4.56.
Highway when I’m babying it I get about 15.5 and in town 14. Nothing crazy but like I said, no one buys a Jeep for the mileage! I still am yet to regear because I want new axles with the gears already in them. Thanks for watching!
@@Montanaoffroad1 Do you have an update on the Sea Foam product yet? Thanks!
@@DonaldChapman Hey Donald, while I feel seafoam is a good product for your vehicle I didn’t not notice a notable difference in my fuel economy. Thanks for watching!
To increase mpg on a jeep do what i did get rid of it 😊
I get 11 mpg with my 2.5l 1998 with 25575r15 😂😭
I’m sure you get a lot of “Smiles per Gallon” at least! Thanks for watching!
What are your favorite trails/ places to take your jeep? I'm newish to the community and don't have many go-to places.
Hey Masen, which approximate area in Montana are you located?
Northwest Montana/ Kalispell area. Aren't new to the flathead, just to the jeep community.
There are quite a few cool places you can visit! Check these out, Blue mountain Jeep Trail, Leadville Jeep Trail, Thompson Lake 4x4 trail and then also join the Facebook group Montana Overland and 4x4 Adventures because there are a lot of schedules trail rides and such that you can take part in. Hope this helps!
@@Montanaoffroad1 Sweet, Thanks a bunch
You bet! Thanks for watching!
I traded my 2017 JKU Rubicon Recon and got a 2021 JLU 3.0 EcoDiesel. Problem solved.🤣👍🏻😉
Hey Rick, I’m sure that did the trick! Good for you! Thanks for watching!
Regarding the sea foam product. I don’t use it, but I wonder if you took the cost of the can into consideration? For example if a can goes for 32 bucks and your tank holds 15 gallons you’ve just increased the price of that tank by $2.00 a gallon. Is it worth it?
Its around 10$ not 32 for reference and you don't use a whole bottle per fill up just for a big clean out its like 1 or 2 oz per gallon if you're looking keep up on it. I usually run a quarter tank with this in it and then a full tank of premium and it does the trick. It helps now and again especially on something that's been sitting or is just old.
Meanwhile Hawaii is at $7.50 a gallon 😂
Yikes! Lol thanks for watching!
Larger wheels/ tires reduces the revolutions of the drive train. It's why 15" tires are disappearing.
just turbo it bang there’s an extra 4mpg 😂
😂 right! Thanks for watching!
Wow did this guy go to mit to learn this,no kidding it’s a square box ,if you want good mileage buy a Nissan Leaf
Good one. Thanks for watching!
Using the Bruce Lee philosophy....lol
No way is it the outside parts. It's definitely the motor and fuel system. No way that the terrible gas mileage is caused by the tires or accessories. It's a dodge. I have a 2014 jk lifted with 35s.
