Engine oil Mobil or Kendall

Over 50k big turbo miles on Mobil 1 10w 30 full synthetic. I love the oil, try some 10w 30 :thumbup:

I'm not really too sure about the weights, but I highly recommend using specially formulated euro blend oil. I believe that is 0W-40. I personally only use mobil 1 euro blend. It is expensive but your engine is not the place to get cheap.

I switched it to Mobile 1 high mileage, and no more smoke, and it now, I kid you not, burns less than 1qt/3-4k miles!

I have a 2010 VW Jetta 2.5 with 48,000 miles todate. The dealer used Castrol and on the last change Valvoline. Now I'm doing my own oil changes etc. Currently using Mobil 0w-40. Since I've had the car the oil level drops so little on 10,000 changes that I can't measure it. The last oil change included 4,700 miles of hot Interstate driving. After it was changed I had the oil tested and basicly it had a lot of life left. Looks like the 2.5 is very easy on oils.

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.
