Engine oil Mobil or Motorcraft

When we tested Mobil 1 on the racecars on the dyno Mobil 1 freed up 6-9 hp over other oils using the same Ford viscosity - 0w/20W.

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.....

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.

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.

ive always used motorcraft diesel oil. 10w30 in the winter and 15w40 in the summer.

Just stick with Mobil 1 0w-40. It's VW-approved and covers just about all operating conditions. There's a reason it's factory-fill on Porsches and Mercedes AMG vehicles

My last Oil change was using 5w-30 conventional oil. Which is much different than the 5w-20 Syn that VW uses.
