Engine oil VALVOLINE or Shell

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 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.

Absolutely. Great oil for your car.

Anyway, when I had my Passat 1.8T and sludge issues were the big fad, my oil of choice was Valvoline Synpower 5w40. It met 502 and was not a synthetic blend but rather a real synthetic.

I have noticed my car is "running better" with the Rotella, and i have not had to top it off at all compared to running Motul 5w40 i had to add quite a bit over my OCI.

I've done 3 OCIs with this T6 Rotella; LOVE it!

For my 2004 VW Golf TDI(125,000 miles) I use Shell Rotella 5w-40 Full Synth.

I use valvoline because it's common and it does the job. My auto mechanics instructor also recommended it because he said most of the engines he'd taken apart that had run valvoline looked pretty crud free.

based on oil analysis done by some members I been using rotella synthetic 5-40 ever since I got the car 7 yrs ago.. while not a group 4 oil it does the job and I aint spending $8 a quart in oil for a regular car opcorn:

I'm using Rotella T6 5w40 in my car. For the money, it's one of the better buys for oil since it holds up so well. It's got good additives that don't shear down quickly, decent amounts of zinc and phosphorus, and it works in just about anything - cars, trucks, diesels, bikes with wet clutches, etc.
