Engine oil VALVOLINE or Shell

5w-40 valvoline synpower is the only synthetic (besides VW Dealer supplied oil) that has VW approval...says so on the bottle if you have a NAPA they can get it for you....i use it year round......

I recently put in Shell Rotella t, 15w 40 and it seems to work a lot better than the castrol 15w 40

Valvoline SynPower 5w40 is perfectly fine for 10,000 change intervals. As long as it meats CI-4 or VW505.00 or ACEA B3, it's a perfectly ok oil.

I too have used the SynPower since 16,000 miles. The tested sample had 8100 miles on it and had very good readings. I also had the Total Base Number tested which is the additive package. It was 2.0 which is low. They suggested I go no longer than 8100 miles on this oil in my engine due to the additives being low.

I ran this fill from mid Fall through the winter until 4/14/03. I filled up with about .25 of a qt 3000 miles into the interval. Analysis done by Blackstone Laboratories. Total miles on oil: 4,886 DAVID: Although we expect an engine’s break-in period to be past by about 10,000 miles, we suspect that the 5 ppm lead we found in this sample is from lingering wear-in. Upper-end wear (see aluminum, chrome, and iron) looks great. Lead should decrease in the next sample, as should silicon, which is leftover sealers used at the factory. Insolubles were good at 0.4%, showing your oil filtration system is getting the job done.

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 am the person who posted those Valvoline 5w-40 vs. Mobil 1 10w-30 results long ago and started spreading the word about this oil and where to find it. The results show that the Vavloline 5w-40 is a very good choice for this motor. The last sample had nearly 9,000 miles on it, and the oil was well within viscosity and oxydation tolerances for 5w-40, and labeled suitable for continued use. Further, after 9,000 miles, wear metals were very low.

I'm going to buy Shell Rotella T 5W-40 synthetic, available at Wal-Mart, for the first oil change I have to do myself.
