    What do you use on your car? I always use Walmart's SuperTech Fully Synthetic motor oil and I use Bosch's DistancePlus filters the majority of the time.

    I have always felt that if you buy a new vehicle that you don't intend to keep for the rest of its life, synthetic oil just benefits the next owner.

    I use a synthetic blend.

    Works great, and saves me cheddar on the full synthetic.

    in a pinch I'll use royal purple, last resort some of the high end Mobil 1 or Castrol.

    Full synthetic. Regular just doesn't last long with the towing and hauling I do.

    I have a Mustang Cobra and a Toyota 4Runner and both get Pennzoil Ultra Platinum 5W-30 and a Napa Platinum filter (if on sale) or factory spec filter.

    Synthetic is a waste if you change the oil at 3000 miles but I have no problem going 7-8000 with synthetic oil and a quality filter.

    I also expect the best out of my 2 vehicles as the Mustang is supercharged and driven fairly hard and the 4Runner is used for towing somewhat regularly. If I had a vehicle that was driven normally, I'd probably just use a quality regular or semi-synthetic oil.

    SuperTech full synthetic at Walmart costs $17 for a 5 qt. jug.

    Never a good idea financially to buy a brand new vehicle, unless you're a millionaire.

    I change my oil every 5k miles or 6 months, whichever comes first.

    Fancy.

    I used to use motul in my STi with a big turbo and built motor because it was recommended by my engine builder. Oil analysis always confirmed it was doing it's job.

    Right up until I wrecked it, that is.

    Whoops.

    Just go with the manufactures recommendation.

    Synthetic is a little thinner than regular oil so if you have leaks, they will seem worse if you switch over.

    Semi-synthetic. Full synthetic seems to cause some clutch slip.

    Regular old dino stuff. Valvoline. Change oil every 3k or so. Maybe unnecessary but it gets me out doing something and poking around the car looking for other stuff that needs to be done.

    I fail to see the point of using blended. Mobil 1 is pretty cheap in the jug at Walmart. Good enough for Porsche is good enough for me.

    So synthetic is better for oil changes every 6-8000 miles?
    What about synthetic oil for new vehicles?

    Every 5,000 miles or 6 months for me.

    Newer cars are actually recommended by their manufacturers to go 7,500-10,000 miles between each synthetic oil change.

    That "every 3,000 miles" myth perpetuated by Jiffy Lube really needs to die. Millions upon millions of gallons of engine oil are wasted each year needlessly because people wouldn't read their damn car manual.

    synthetic lasts 2-3 times longer than regular, so you don't have to do an oil change as often. I know a few people who use full synthetic and don't do oil changes after 10k miles without any problems.

    It's good to use synthetic from the start on new vehicles.

    Must be a bike thing

    For oil its Schaeffers filters are fleetguard

    Do not trust AMS to 25k. It looks horrible at 25k

    FYI.

    Mobil 1 "full synthetic" is not a 100% synthetic oil. It's refined dino oil with some blends of synthetic additives, essentially a synthetic "blend". The only true 100% laboratory synthesized oil is Royal Purple and Amsoil.

    The consensus among mechanics is pick an oil type and stick with it. Never swap back and forth. Synthetic oil tends to reach deeper into crevices than mineral oil. So if you used mineral oil, there could sections in your engine that never got good oil flow. Gaskets in those sections are essentially held in place by old oil gunk. That gunk could last the life of the car, so it's not all that bad. However, if you put synthetic oil in there, it could flow into those sections and knock the gunk off, creating an oil leak.

    Rule of thumb. If your car came with synthetic oil, then use synthetic oil. If your car never saw synthetic oil, you're risking a leak by switching.
