Engine oil Castrol or VALVOLINE

Generally, brand matters a lot. Amsoil, Mobil 1, and Castrol are all great.

I run Castrol in my older cars and Mobil 1 in newer cars that I care more about.

I usually change the oil every 7500 miles and tend to use Castrol synthetic 0-40.

I just use German made Castrol Edge 0w40 (502 certified) oil. Ive used this oil since the car had its first oil change and it does not burn a drop and car runs great, i now have 59k miles and shes drives new as ever.

I use 5W40, Castrol Edge, has the 502/505 certification, if it doesn't don's use it. You can use the 0W40 European Formula as found at Walmart; is also 502 certified.. This is a good all-year 'round oil.

Castrol EDGE 5w-40 is what I use.

Did another oil change today, and not a lot of consumption, still pulled 6.5 quarts out of the engine. Been using the Castrol Edge 5W40, and on the back has the 501, 502 and 505 certification.

I use Castrol syn in our VW because they call for Castrol syn. The only thing I've found is that our VW which called for Castrol Syn 0w20 always sounded clattery - until I switched to 5w30. I guess we are suffering a little MPG at the cost of a quiet engine but I won't use the 0w20 again.

As someone mentioned the Castrol Edge 5w-40 (black bottle) that Napa carries is probably very close to VW OEM dealer oil. If it is good enough for Porsche I am sure it is more than good enough for VW.

Just changed oil today (same oil as above) at 104,728 miles. Purrs like a kitten.

Valvoline Synpower 5W40 I've been running this (VW 502.00 approved) in our '07 Audi 2.0TSI for over 100K mlies, 10K oil changes, and no issues.
