Engine oil Mobil or VALVOLINE

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.

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.

When I dumped my dealer Syntec 5w-40 for M1 0w-30 in Dec, it was night-and-day. Way lighter and better.

Just changed my oil in my '02 Camaro. It has the LS1 and just rolled over 150,000 miles. I use Mobil 1: 5w-30. It hasn't seen anything other than Mobil 1 so that's what I use haha.

Mobil 1 extended performance 5w-30. I don't drive many miles and I want the extra life of the oil in months. Plus Mobil 1 is factory fill on my LS2.

I ran Mobil 1 or German Castrol synth in my BMW (inline 6), and run Castrol GTX in my v8 truck.

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.

I :heart: M1 0w-40

I love the Mobil 1 ESP 5w30 for normal duty. It meets the latest 504.00/507.00 VW standards (newer than 502/505), and is specifically designed for diesel motors. Turbos are tough on oil, and diesel oils take prolonged periods of high heat much better.
