Engine oil VALVOLINE or OEM Volkswagen

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.

Strictly anecdotal, but at 56,000 I switched from the usual suspect Castrol to Valvoline Synpower. Engine starts more smoothly and observed mileage on highway has gone from approx 30 to approx 34 mpg.

Given that it's almost guaranteed that this was not a turbo engine originally (the lack of factory air filter is another clue) she'll run hotter than usual and so a quality oil is a good investment.

I use 20/50 Valvoline year round....

i run 0w30 in my jetta 2.0. fully synth. have for 33,000 miles, no problems, other then better gas mileage

I was recently obsessed with oil in my 01 1.8T. I was at http://www.bobistheoilguy.com alot and determined that Valvoline Synpower 5w40 was the way to go based on oil analysis and availability. Castrol Syntec 5w40 appeared to degrade faster and the viscosity wasn't near as good as the Sypower after only 3k miles on it. IMHO Synpower outperforms Syntec in our motors based on actual facts and numbers from the oil analysis.

I use only valvoline 10w60 in all turbo motors

Valvoline Synpower 5w 30 is on the approved list for VW usage, doesnt make it THE choice but whatever floats your boats I guess and in this case it looks like R P floats you the best

Valvoline SynPower full synthetic ) 5-40 (P/N VV966) is not on the VW approved oil list. But it certainly is approved, just read the label on the bottle:\"VW 502/505/505.01\"

A lot of the guys I know ended up running valvoline VR1 20W-50 (A Dino oil, fwiw) because that was the only thing that keeps their rod bearings alive for more then a couple of weekends. Switching from thinner oil to that made the difference between changing bearings every couple of weekends to once a year.
