Engine oil PENNZOIL or AMSOIL

i change at the extended interval and use only 100% synthetic oil usually Amsoil. I plan on using the same in my TDI at the normal service interval unless vw makes a full syn diesel oil

The only oil I used in my Audi before Amsoil was Mobil 1, and this far surpasses it.

You will not get better, check the results yourself, I gained 9hp and 6 ft lbs of tourqe and increased my gas mileage per tank 35-50 miles.

But from my experience with it, it has made a difference in several of my vehicles (not only VW).

i have used Amsoil for going on 10 years with great success. I have never had a problem or failure with anything i have used it in.

I used to use mobile 1 fully synthetic 5w 30 with a quart of lucas synthetic oil treatment and it work pretty good and i could get about 5k out of it. I just got hooked up with an amsoil dealer so im now using amsoil's european 5w 30 and im going on 7k and its still pretty effin clear

Been using AMSOIL since day one of my first oil change. Damn good oil.

The oil comes out cleaner with Amsoil. I also notice much less oil loss/evaporation with Amsoil compared to Mobil 1 or anything I've used. With Amsoil the level does not go down at all.
