Engine oil AMSOIL or OEM Volkswagen

i run 5-40 amsoil in my VRT as well

It's a little more pricey but extends change intervals and has worked for me. Keeps engine temps a bit cooler as well.

Now i am referring to amsoil, Delo 400, mobil one turbo deisel truck oil.

in my Diesels i use amsoil or chevrons delco synthetic for heavy duty diesel engines.

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

Given that it's almost guaranteed that this was not a turbo engine originally (the lack of factory air filter is another clue) she'll run hotter than usual and so a quality oil is a good investment.

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.
