Engine oil Mobil or AMSOIL

I just changed the oil in my car and I used Amsoil 5w40 European blend. No complaints so far.

i switched from castrol syntec 5w40 to mobil 1 0w40 when i went turbo and i noticed faster spool up and 9 degrees colder oil temps during hard drivin.....

I wouldn't use anything other than Amsoil I recently purchased some to change my R's oil soon.

Mobil 1 0W-40 can be had at your local walmart. It's quite a bit cheaper at walmart than the auto parts store.

technically you can use Mobil 1 Euro Formula 0w40 in the GTI and the Phaeton because it has the VW502.00 certification.

I was able to document that the oil was VW 502 certified Mobil 1 0W-40.

I do my changes @10k with UOA. 2nd change was with 4 laps on the Nurburgring and about 1500 miles @125 MPH. At 10k The report came back that everything was fine and the oil still had life in it. With my K04 it came back fine also. I drive the piss out of my car.

Yeah...same reason I switched. I love Amsoil...and so do my engines trannies and diffs. It just gets too expensive using the Amsoil engine oil with the oil change frequencies that I use ( Every 8,000KM ).

Rotella T6 here. I was a long time Amsoil guy, but it's just too fracking expensive, especially with the amount of miles I drive a week.

Yeap, running it in my 2.0 8v rright now. Will switch to M1 10w-30 or 10w-40 this summer, back to T6 in winter. Got 206K miles on the car.
