Engine oil Mobil or Shell

I just did the 4th oil change (first non-dealer change) on our 40k mile Tiguan TSI and used Rotella T6. I use it in my stage 2 WRX and think it's fantastic, so why not in the TSI. Great oil overall.

I run the T6 in my 2.0T FSI.

Rotella T6 5w-40 is a great Diesel full synthetic.

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.

Another vote for the Shell Rotella 15w-40. I run it year round in my Rabbit.

I use Shell Rotella 15W40. It is C grade oil specifically for diesel engines.

This is a 2009 GTI, just over 27k miles on the car, and 10,000 miles on Rotella T6. Car is tuned APR stage 1 93 octane, and has a Carbonio intake. I had some concern that maybe I didn't oil the air filter enough, and it looks like that is verified with the high silicon.

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.

Just changed my oil @ 2k with Rotella T6. Sounds much quitters and feels a lot smoother. I've always used this and it's a damn good oil.
