Owner reviews for engine oil

i use 0w-40 on my vr6 with 80K miles. runs fine

on both my current 1.8T VW'S i use Valvoline Synpower 5w-40 Full synthetic- it's an oil that is approved by VW...and has all the right cleaners/additives in it.

Put in 4.0 US Qts. of 0W-40 Mobil 1 (extra due to larger filter). Started the car briefly to check for leaks. Based on my measurement, with the new larger filter, 4.0 quarts will bring you to about 60% up the crosshatching on the dipstick. So, I added another 1/4 quart (8 oz) and that seemed to bring it right to the top. So, 4.25 quarts is what I will be going with in the future.

I've used the Marvel oil in my car...it does wonders on keeping those lifters lubed better...I used in my Corvair... I mixed it w/ my oil..

It's best used to quiet down noisy lifters, and it works well for that. It will also clean up the inside of the engine a bit, but you can use ATF for that(which is cheaper).

To bad Walmart stopped stocking Mobil Delvac1. $32 + tax for 4L of full synthetic. Probably one of the best, if not the best oil for Pre PD TDI's...

The oil used by VW is made by Castrol. Of course, you can't buy it in any store.

AMSOIL is definately the best oil to buy, but its expensive and hard to find (unless you order it - amsoil.com).

i just did my first oil change with amsoil 5-40 European blend. i heard stories about mobil1 burning oil more than other synthetics.

AMSOIL oil and filter. I swear the butt-dyno gave me a few ponies after switching from Mobil.
