Engine oil Mobil or VALVOLINE
No you aren't a guinea pig. I have been doing extended drain interval for several years now on a chipped 1.8T. I run M1 5W-30 and average 17-20k between oil changes and currently have 200k miles on my '02.
Interesting. I've been using Valvoline synpower 5w30 since 5k miles, currently almost 75K miles.
I've always used Mobil1 0W-40 and never had oil-related problems. In fact, my Dad used it exclusively in his 1988 Chevy S-10 pickup and only changed his oil once a year for the life of the truck. Today it's still running strong on the original engine with over 200k miles on it. And that's only changing the oil ONCE A YEAR!
use M1 0w-40 in my girls Beetle S. works like a charm. currently i'm using AMSOIL 5w-40. going to switch to M1 0w-40 after this.
im running 5-30 mobil 1 full syn. ive notice the car is QUIETER with less valve noise, its been 2000 miles so far on the syn oil, and its still clear, lookin got 8-10K outta it...
i use 5w30 in mine and it runs great. really quiet.
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.
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...
