Engine oil Mobil or Shell

I will also use a zero weight synthetic like mobil one.

I just switched to Mobil 1 for the last interval and the engine ran much better on it.

I used 5w40 Mobil 1 Full Synthetic in my 08 Passat. Had such great results, I carried it over to my 12 R Line.

Speaking of Rotella, Here's a personal observation of mine. My beater Saturn 1.9 has a lifter tick (not fixing it, don't care), so I just put in Rotella T, and it quiets it up a bunch!

ROTELLA T6 - Instantly i noticed a very nice purr from the motor. Its a heavy oil and with stabilizer (in this case thinner than the oil) It warmed up slower, meaning that it was absorbing more heat. No extra start up noise at all. The biggest gain from the Rotella was hot weather stability. It seemed to perform the best when you drove the car hard! Hot weather didnt affect the engines power anymore, and that made me really happy. Turbo lag was increased slightly, and the engine revved slightly slower, but remained perfectly stable. I loved this oil for protection, its really good for hot weather!

I'm running T6 in my car as well It's been great the last few changes, best oil I've used for my 1.8T and I have over 190k on my engine.

I did my 1.8T AWP valve cover gasket two weeks ago and I can highly recommend Mobil1 0/40. Used it since 3/2002.

Jumpers, disc golf bag, sleeping bag, old winter jacket w/ wool socks, OEM jack w/breaker bar, 4 qt Rotella T6.

Mobil 1 10w30 with a bosch filter up here in Canada. Haven't had a tick since I started using it, at 110k km my engine is in good shape to begin with though.

the Mobil 1 is the 0w40 Euro Formula, and has the VW502.00 approval that being said, Mobil 1 5w40 Turbo Diesel Truck is also a good choice, but no VW approval.
