Engine oil Mobil or AMSOIL

I use Amsoil Heavy Duty Diesel marine and truck oil.. it's preety good.. should be TDI friendly.

I have seen NO reason not to use Mobil 1 5w40 in a NON PD TDI motor. I know many that use it and no problems RELATED to oil. They do not coke up and the wear isn't there. I have used 5w30, not even 5w40 Mobil 1 in my VW/Audi 2.4L engine in my Volvos for years and have seen the best results

I have used both 0w40 and 5w40 Mobil 1 in a 02 Jetta for a long time with great results.

I have used Mobil 1 for years in Volvo diesel cars, and they are known for cylinder wall wear, of course its a VW Audi engine. With using Mobil 1 5w30 over several hundred thousand miles, I have seen zero wear and have not needed to adjust the valves once, in several engines. I am convinced it works well.

AMSOIL was my race sponser, and I've used their products in all of my racers including the SC'd 2000 4Motion. That being said, I wouldn't recommend running any engine oil ; including high-grade synthetics, over 7000 miles.

I used mobil 1 5w30 when I did the 10K oil change as well.

i use amsoil 5w30 love it

my v6 consumed almost a quart during the first 3,000 miles then it stopped (zero oil consumption!).

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.

I ran my 2K beetle for 21K miles on Amsoil 5-3o/5w-40 and milage went up 7% and started awsome when it was 0 degrees out . Now I have a 2005 Jetta and its next for the 5w-40 @ 5K oil change .
