Owner reviews for engine oil

i use 5-50 non mark (mobil 1) my egine dont sound and my car dont need that weekly oil refilling any more

Surveys on several VW forums have Castrol 20w50 a clear winner for quality, price and availability, but other good brands like Valvoline, BP, Shell etc get honourable mentions too.

If you run it HARD than a 20/50 oil is good. I run castrol non synthetic, but I'm thinking of switching to Royal Purple. Still want to get more opinions before I do the change over but I heard good things about that brand.

castrol 5-50 synthetic in my vr6 passat , 5-40 mobil-1 delvac in my TDI passat.

Due to the higher milage on my motor I run synthetic 15W-40 (Mobil 1) year round.

I use regular, dino, Mobil 10W-40. I got so many miles on my Passat(185,000), that I don't using synthetic Mobil 1 would help much.

you can buy Valvoline Synpower at any NAPA Auto Parts Store.

Go with the Shell Rotella 5W-40 available at Wal-Mart

Just go out and buy Valvoline SynPower 5W40...

I have decided to use Castrol GTX 5W-30.
