Engine oil Mobil or VALVOLINE

i've gone M1 0w-40 and love it but i might experiment this summer

I run M1 0w-40 and do that at about every 7k and it could prob go longer.

I'm going on 5 years 1 month using M1 0-40...I did try Castrol 5-50 once just to try it out, and the engine behaved itself...both synthetics and about $6-7/qt...

I'm sticking with Mobil 1 0w40; it's always been an excellent engine oil for my cars.

my gti loves mobil 1 10w-30. beenn using it for 170k with no issues

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 run mobil 1 synthetic 0w40 all year round, with no problems. Best of both worlds

The car itself is outstanding for the price, excellent quality build in my opinion. However the FSI engine has given a few of us some headaches. Mine performs great, except for burning excessive oil.

I use only valvoline 10w60 in all turbo motors

I've moved up to Mobil 1 5W-50 from Syntec 5W-40. So far I really like it. No noise on startup at all with it. I also use the monster oil filter.
