- Опубліковано 28 тра 2019
- This test needed to be done to get raw pure scientific results. Some got MPG gains after upgrading the spring, so I get to test it, the MPGs 10-60 30-60 50-70 etc, let me tell you these tests suck!!!!! Not being able to drive the truck how I want to and have fun is no fun!!! All this for science!! Lol

I replaced the spring in mine for a stiffer one, took out the screens in the fuel tank, added an additional fuel filter and it definitely has helped.
The biggest thing the stiffer spring did for my 7.3 was on extreme cold start ups . Definite improvement
THE DISAPPOINTMENT in his voice when he saw mpg decrease lol😂😂😂😂
I just bought a 7.3 I just did a 42 miles trip it went down from 1/2 tank to 1/4 it has a superchips the old version the video is very informative thanks
Great video nick and always
Thanks
Lol the changing your feet while walking with the music was funny
Lol thanks gotta have fun
Great editing
Do you live in Ca? In other words, do you have to get emission tests? I am wondering if that air filter will pass.
I have an Excursion with the 7.3l, and that filter is the first thing I did. Every now and then the engine would lope oddly, I did not like it.
Installed the OEM motorcraft filter, loping never came back and I did not feel any power decrease, other than a little quieter....
If your tank is harpooned and its already maxed out your fuel level sensor in the tank, it wont' start to show movement until the level drops enough to move the sensor. In that case you have to calculate it like you did. The LieOmeter will lie to you in the short trips but on the long trips, if your tank isn't harpooned will be fairly accurate. Thanks for the video Nick I purchased the RiffRaff and should be installing it in a few days. Thanks for the tips on the getting the spring in without needing a new line seal! Thumbs up! Best Wishes & Blessings. Keith Noneya
@ 21 :51 what app are You using? Want to do this, BUT IF O ring leaks what is Ford part # to replace it ? Not sure what you call it,What camera are You using at 14:02 ?
What is the name of the app you use for the mpg calculator?
Just recently found your videos and enjoy watching them , good info , and fun to watch. Now something to consider is the quality of the fuel . Im sure that most people who drive diesels have run across this from time to time and it does makes a huge difference.I switched jobs a few years ago and started getting fuel up in that area and was like WTF. I went from 400-425 miles per tank to 540-550 per tank with out doing anything , I got fuel in my home area again and went back to old mileage then filled back up in new area and right back to 540ish again obviously the only variable was the fuel so needless to say I continued to get fuel at that gas station the remainder of that summer till the winter blend came in and then it completely tanked out to shit winter mileage . So I’m a firm believer in good diesel vs the shit that they normally sell to us on the daily makes all the difference also . All my truck mods are is a edge tuner, muffler delete, and a k&n filter sitting in the factory lower filter box in a 02 super cab 0n 35’s w/ 373 gears 29 gal tank and 250k on the clock ,since then I’ve stayed stead at the 350-400 miles for the last couple years now w/300k on it
Great video. I just ordered an upgraded spring from riffraff diesel. I was really hoping for a little better mpg but I will take the running smoother and other benefits over that. I do get between 19-20mpg on the highway in my 2002 f250 2 wheel drive auto. I use cruise control set to 1900 rpms. I read on a forum somewhere to keep it there to stay out of boost pressure. It does keep it very low boost 3psi or less unless on a grade. I use the torque pro app to monitor boost through the map sensor along with rpms. The only thing I have done is removed the aih and cut it off and screwed it back in along with a 6637 filter. This is unloaded with 265/75r16 tires. I run 65psi in the rear and cant remember now what I run up front. It is within 3psi of the rear if I recall correctly. I don’t keep track of in town driving but I think it’s around 14-15mpg maybe. I also just replaced the eot sensor. I was having really rough idle until warm and that made a huge difference in the starting before it was up to running temp. Once warm it ran fine.
I just currently got 17mpg not really trying, last time I tried to get best MPGs I had 16.1
@@FixItNick that's not bad. Your truck is bigger than mine also.
If your truck is 4x4, then that is the one I've wanted, crew cab dually zf6 4 wheel drive, don't get me wrong I love my 94 but I like the sd 7.3 as well.
what are u using on Ur phone for comparison?
Part of the reason your mileage was lower on second run was the speed tests were in the second tank of fuel thus affecting the mpg.
What do you mean by 86d spring
I dont know if you realize this or not but you are slowing yourself down by revving the engine so high. The 7.3 was originally designed to make power at 3,000 rpm which for that year factor would be 275hp and about double the torque at 2,000 rpm. If you redo you speed test shifting right on 3,000 rpm you should actually see a slightly faster times. It's not going to be a massive difference but it is worth noting.
I just need tunes
On a complete fill up on my 29 gallon 2001 f250 7.3 tank it will stay full for around 80 to 90 miles then go down, but with the hydra chip turned up it goes down quicker due to it going out the tailpipe, aka smoke haha
Haha after I install exhaust I’ll prob never drive normal again lol
Anyone changing that spring without a pressure gauge hooked up w a hand one the key is rolling the dice on blowing seals. The blue one on Amazon hits 115psi. Not good
Awesome HAI kit (hot air intake kit)
Anyone driving Excursion and having MPG issues. I have a 2001 and really can't better than 9-10 mpg. Lots of city driving and maybe a little heavy on the throttle. Lots of mods, turbo rebuilt, fuel bowl, 4" exhaust, oil crossover, up pipes replaced, EBPS sensor and tube replaced, boost is good....been running seafoam and know lot of these mods not for MPG, but she running like a champ and MPG still really low. It is lifted with 35's with 220,000 on it.... any ideas would help.
With what you described that’s about right. Hydra tuner would help with MPGs tho on economy tune
Thanks Nick, hope to see some videos soon, yours greatly helped me in my 7.3 mods.
@@scottd.6581 is the speedometer correct? if it's not tye mileage will not be correct. the 35s are probably throwing the speedometer off.
Maybe ICP?
u work for ups and r u in feeders or package delivery? Btw I love your videos on your truck
Yes feeders, thanks man
@@FixItNick that's cool I work for the railroad but my dad has been with ups since 1990 and now in feeders for the past 4 years. sorry anyway I can't wait for your next video on your truck
I recently bought a spring as well and I seen my MPG’s go down .. i’m going to put back to stock spring... what a waste of money..
Same spring? Recently? I thought maybe it’s just me, so that’s weird, I’m a little upset, but it does run faster 30-70 and 50-70 pulls, but I prefer the better MPG tho honestly.
Same thing here need them MPG‘s
Andrei.B I’ll be doing couple more cheaper mods to hopefully help with MPG
Never got more than 15 empty and 13 towing under 10k and ten hauling 15-17k.
The purpose of the spring mod is to run richer. It did work. I would have reboot the computer each time it was switched.
Why reboot? that won’t do anything, but driving it should let it learn more I think
the fuel pressure has nothing to do with the computer it's all 100% mechanical
There is a diesel mod out there that will improve the mpg it is a program that was tested by Ford..I will check into it. 20mpg
Let me know what it is, I have a thing coming lol
What the mod? I am tired of getting 12 or 13 miles per gallon. Would love the bump in mileage.
Did you ever find the mod?
Something that will give you 3 mpg increase is switching engine oil, rear differential lube , Tcase and transmission oil to Amsoil synthetic oils, they are a Tier 5 oil, most of the other ones are tier 4 basically warmed over petroleum oils.
As a fleet mechanic every vehicle we switched to Amsoil synthetic saw no less than 3 mpg improvement or more.
Amsoil full synthetic oil is not oil with an additive package but designed creating sphere shaped molicules unlike petroleum oils that look like goathead shaped molicules that create internal friction where Amsoil molicules are round and glide over each other.
The film strength is more than 10 times greater than petroleum oils.
I sold the motorpool manager on switching the fleet, almost 200 pieces of equipment to Amsoil
By switching all the lube on a 95 FL60 to Amsoil synthetic, wet front hubs, engine 8.3L power steering fluid, transmission, Allison 3000 series 6 speed auto rear differential and greased the
U joints.
The truck had 95,000 miles on it at the time. Was bought new and the fuel use data showed 6.3 mpg.
After 500 miles I started tracking fuel use, 12.6 it eventually leveled out and stayed at 14.2
After that he went to accounting and budget manager for approval to do the entire fleet, which was done over the next 2 years.
Every vehicle, car, suv, pickup truck to class 8 saw the same increase.
I've used the products and switch other customers to Amsoil synthetic with the same results over 40 years now.
It is money in the bank to use it.
Question. Anyone ever put a bb in one of 2000+ 7.3? I’ve heard it done in the old 7.3. Curious if it’s ever been to the newer ones.
What's a bb?
that's older obs trucks with mechanical fuel pumps these trucks run strictly off of a lift pump on the frame
I believe you can still use the bb on the 7.3 99-03 it just sits in the spring housing under the spring
@@rickfowler5342It’s what you shoot out of a BB gun. Did you not ever own one?
What gearing is in your truck, my 2000 with a zf6 sits at 2500 rpm’s roughly at 75 mph
Same as mine, you have 4.88's I presume?
@@tibrin7696 found out zf6 7.3 4x4 came with 4.10 and my truck is on 35 inch tires
@@brianowens6132 Ah....ok...I'm on skinny winter tires atm... I did loose some mph cause I dropped sidewall height... With normal 235/85R16 tires, the rpm at 70mph is adequate...but I'd take a 7th gear any day lol.
When you filled up, did you let it click off and stop once or did you keep filling it until it was in the neck and if you did fill it into the neck, did you do it the same both/each time(s)? If not then your numbers will be scuwd
absolutely, once mine clicks off by itself and the foam settles I can get 3 to 4 more gallons in my tank. always pump till I can see fuel in the neck. that's how to get accurate numbers for mpg.
@@PowersPlays97 👍just wanted to make sure you are working with the same numbers
Sorry Nik but nobody has ever shown the proper placement of popped seat.lol I had mine in backwards, the seat has to have the 45 angle towards the fuel bowl.
the ONLY way you will get 25 MPG in that truck is behind a Tow truck and the engine running at idle
A ram tow truck is what they really like to ride on.
Clean injectors help I run 5 gallons of transmision fluid and top off with diesel every 4 -5 months I pull a 27ft fifth wheel I’m running 35” tires and on the freeway I can average 14-15miles per gallon not pulling I average 18 miles per gallon stock 7.3 clean fluids and clean injectors help
What’s your truck specs?
FixItNick what specs are you referring to gears ? I have 373 gears.
Taco like 4x4, dually, loft, stock tires, tune etc
FixItNick 4x4 35” tires single rear wheel leveling kit no programmer I have cold air intake straight pipe exhaust 4” turbo back 3:73 gears 235k miles stock turbo stock injectors
IMHO you need to stay at 70mph for how ever long you want, this will give you highway mph. I personally think a stick shift truck you can't stay consistent enough to get a accurate mpg driving around. I personally love the 86 spring, my dually has a smoother idle, and better throttle response which I will take over any loss of mpg, if you want too make a donation my other 7.3L (F-250) needs a 86 spring also.
Haha DM me on instagram, but my driving characteristics were identical I made sure of it :))
@@FixItNick I don't have instagram :-( and what does DM mean??
What is with the melancholy music? Weird choice for this kind of video.
Lol love it or hate it, I’ll try to improve
power and MPG are pretty much always a trade off.
Sadly
Not really with a 7.3 because most people above the 400hp range are getting better fuel economy with proper tunes.
Nope. That's impossible. An economy tune may help for mpg but a power tune will never get better fuel mileage if figured using actual math.
👍✌️
Thx
I still want to Buy the Truck... 3
Actions speak louder than words lol
Hello
Yo
Priuses don't get good mpg vw tdi do 60 mpg get a VW
HERE IS WHAT YOU DID WRONG. GO TO SAME STATION FOR 4 TO 5 TANK FULLS. WRITE YOUR MILAGE DOWN OR SET YOUR TRIP ODO. THAT WILL BE YOUR MILAGE.
Nah lol I can’t drive normal for 5 tanks I’ll go nuts
