      *Scotty, i have a question.* I have a Cadillac cimarron with the two liter inline 4. It's got only 98k original miles. The previous owner couldn't tell what sort of oil the engine has been using. I changed the oil as soon as i got it and put in 15w40 semi-synthetic SN. Is it OK to run this engine on full synthetic or what is the explanation and logic behind this? THANK YOU!

    • @justacinnamonbun8658
      @justacinnamonbun8658 5 років тому

      Giovanni Laux Wow, you have a Cimarron?? Don't see those too often. I don't know about Scotty but I would use conventional or a blend, don't know if a full synthetic would do any good if you don't know the oil change history, this is an 80s car and as such, if it has the original seals which I'm assuming it does, they're probably brittle by now. Using a full synthetic might be a bad idea. I don't even know if I you can get 15W-40 in full synthetic. Never looked for it.

      I actually got one of these a few days ago on a used car I just bought. The used car dealer overfilled the engine oil big time and they used conventional. One night coming home I decided to floor the car and it went in to limp mode. I bought MAF cleaner but I was worried about the engine oil being so full so I got it changed + an engine clean at Valvoline. Car only has 40k miles but I want it to last 400k.

      Unless a hole is going to be made in the engine after a flush, what's the risk other than preparing to bear the cost to replace seals and gaskets? Replacing the engine? Even then, is that such a bad idea if you plan to keep the vehicle? Will the engine keep running with the build-up inside? Or the recommendation is to replace the engine or buy a newer car when it breaks down.

People aren't exactly truthful about what they've done to take care of thier vehicles especially when selling. I do it so I personally know what has been done and hasn't left me stranded yet.

I did the flush and changed oil brands, that was at about 190k miles and used the car in my work until I retired and had about 230k miles on it.

    If your engine is over 200000 miles, leave it alone and just change the oil and filter every 3/4k miles, Scotty's right about the seals.
    If your engine is below than 200000 miles and changing oil and filter regularly, you don't need a flush in the first place.
    Only flush your engine if it's below 150000 miles and has doubts that the previous owner didn't really care about changing oil regularly.

    Great video Scotty! I've been religious about changing the oil in my VW Passat, and now it's up to 102k miles and still hasn't burned a drop. One thing I've wondered about though, is, should I change the transmission fluid in it? It's a 5 speed manual, and still shifts fine, and the clutch doesn't slip. The dealer told me it was a "lifetime fill" and I said "Define lifetime." I keep cars until the chassis rusts out. Judging by how this car is built, I'm hoping to get at least 500k out of it. Averaging 33k a year and so far it's been great!

    • @saultube44

      Lifetime means: use it until you break it, then buy from me a new one, don't maintain it, because it inconvenience my business; I don't care about your economy, I care about my greedy bonuses.

    • @heidis8713
      @heidis8713 2 роки тому +6

      The transmission fluid lasts the lifetime of the transmission. The lifetime of the transmission will be greatly reduced if you don't change out worn / dirty fluid. So, really, any fluid could be "lifetime fluid". Pour some pancake batter in there, and a week later, when your transmission falls out the bottom of your car, it could be said that the batter lasted the lifetime of the transmission. What I'm trying to say is I don't believe them. Change your fluid regularly. Or at least drain a little out to check it.

    • @chiefdenis
      @chiefdenis 2 роки тому +4

      Most manufacturers advise you to change the mtf after 100k miles, 75w90 is cheaper than a gearbox.
      Also you probably think it shifts smooth because you've psychologically adapted to it.
      My shocks kept deteriorating but i kept putting it off because i thought they weren't too bad, when i got to put new shocks in, the ride quality was simply night and day, and i realized how I'd been tricking myself into thinking that it wasn't so bad.

    I bought a car with 100,000 miles on it and looking in the valve cover it looked very clean. After about an year the oil pressure would wave all over the place and sometimes would drop to zero with no engine clatter. I added about a pint of MMO and drove it a couple a thousend miles. For a while the oil pressure would wave around and then became steady. Changed the oil and no more oil pressure problems since and no leaks or smokes and does not use oil. I did not want to pull the pan to clean the pick up screen.

    Best way to clean engine internals if you are in doubt:
    Change the oil and the filter, drive around for 1000 km and do another oil change. This won't cost that much more than a bottle of flushing agent and won't harm your engine.
    Best way to keep your engine internals clean: do proper servicing with high quality oil and shorten the drain intervals just to be on the safe side.

    • @KingOath
      @KingOath 5 років тому +2

      Tristen Dragon Exactly, but even then, if it’s only going to be used for a thousand miles as a flushing oil, you don’t need to buy the good quality oil you’d normally use. Just wait until your auto store has a big sale on and buy a heap of the cheapest crap they have. It doesn’t really even need to be diesel oil.
      A trick my old man used to do was to keep the old used engine oil from his motorcycles for this purpose, if you have a modern sportbike or similar and you’re using high grade full syn and changing it regularly like you should in a high performance machine, the oil that comes out really isn’t anywhere near the end of it’s use by date on oil changes. On a newer bike engine it’s often barely dirty at all and perfectly fine to use as a flushing oil in your car or to re-use in your lawn mower 😁

By trial and error I found out, for myself, that an initial engine flush, right after purchase in adition to air intake clean not only improved the overall performance of those cars measurably, but in many cases also quitened the engine noise conciderably. Additionally changing ALL fluids in the car has lately becoming rather the norm for me. Sidenote: most cars I bought where between 6 and 12 years old diesel, regularly used with an average between 100k and 150 k miles.

    Sadly from personal experience, I can attest to this video. I ran seafoam through the oil and did the intake treatment on two of my older vehicles. My car started ticking in the engine and leaking oil from the valve covers on top of my spark plugs. The truck simply started leaking oil, which it had never done before. Yes, after initial treatment, the vehicle ran better, which is why I did the other, but within 6 months, I had issues with both. With higher mileage cars, leave well enough alone until there is an actual problem! Also, screw seafom except for gas treatment and specific purposes. I wish I had that minor gunk build up back now!

    Thanks for content you provide. I enjoy the videos very much. Questions for you to the topic for this video: 1) vvt is typical for non-American vehicles, so let’s preface that- but why would you want to avoid fixing a problem being hidden by the “sludge”? I eat right to be healthy, but I go to doctors to know that I’m healthy..cause I ain’t fooling myself thinking just cause eat good, then I must be healthy. If I have potential oil system issues, I would rather know and repair them to restore my engine power, lifespan, and ensure optimal performance. Unless I bought a piece of junk, why would I treat it with less care? 2) just because newer oils have detergents doesn’t mean oil build up cannot occur, regardless, due to the combustion process it is a naturally occurring problem that comes with territory. I’ve taken apart well maintained engines and found varnish or cooked on oil and coated oil pans still, so I believe that an addition of an additive once a while will do more good than harm. Plus, I would find my potential oil leaks before it turns into blown head gasket or something. 3) due to dirt entering the engine thru air inlets, completely unavoidable, and modern recirculating emissions, engines are very sensitive to contamination changes- maf, Inc, throttle bodies, maps, o2, etc- all these sensors can be impacted and cause deterioration in performance and mpg if additional care is not given, and can lead to premature failures that were probably avoidable.

      I get what he's saying my 150cc scooters performance has only gone up after not giving it for service.

    Hi @scotty. i appreciate the details. thank you. the oil in 3Year Old car should have been changed 30k km ago but was not. sludge can be seen when the oil cap is opened. i guess it would be difficult for you to tell without seeing but what is your gut feeling? should the oil and filter be changed or should the engine be flushed at first?

    Hey Scottie, great vids and info. Thank you. Have you or do you plan on doing a video concerning BG products? A freind turned me on to them and so far they seem to work great. Thanks again...

    Thanks for the advice. I just recently flushed my engine. If any engine of mine was functioning by the grace of sludge and crap not dislodging then I would rather know just after a service than in the middle of a holiday.

    I have flushed engines since the late 70's and never had a problem. But the more I watched your video here the more it makes sense as to what you say. I do remember rebuilding engines and changing valve cover gaskets on 1960's and 70's chevy 350 and 400 small blocks and yes tons of sludge. But then when i did the same in the 90's and later not much sludge and the detergent oils kept them clean as you say. Very good video you have done here

    Hi Scotty, you are amazing, thank you for sharing your knowledge on auto repair, I learned a lot following your videos and advice but in this matter I disagree of not flushing the engine. I have a 2011 Buick Lacrosse CXL 3.6 liter engine, I had 7 check engine codes pop up, went to auto zone the kind lady behind the counter said do yourself a favor get a new car because it will cost you an arm and a leg to do the repairs, went to the dealership I'm not sure if they quoted me $9,700 something or $11,700 something. Scotty I gave my cousin who is a mechanic a call and he recommended that I flush the engine before getting rid of the car or paying a shop the arm and a leg lol. Scotty I flushed the engine, changed the oil and started the car believe it or not the check engine light went away and went back to auto the zone and no codes whatsoever, it's been now over 6 months and thousands of miles driven, the car runs excellent when idle rpm is less than 600, please share any knowledge on how this flush saved my car, you are a hero in my book, God Bless You for all you do.

    Hey Scotty I blew a head gasket and I’m planning on fixing it today. What would you use to clean the oil/water mixture?
