I also have a 2.0 and run the valvoline synthetic. I started after 2500m and am currently at 29k. No scientific results here other than keeping track of mileage in a little notebook and looking back at the first month compared to the most recent - I'm averaging about 7mpg more.
All these problems are not present in the Valvoline SuperSynth 5W-40 sample. Furthermore, the results from this Valvoline are well below the Universal averages for this engine. This suggests that I should be able to run this oil for at least another 1000-2000 miles and still get an excellent report out of it! With it, my engine runs bit smoother and quieter especially at idle. At high engine speeds the engine feels more responsive and more lively. Another difference is that with Valvoline, I am observing improved efficiency. My 2.0 broke its own record of fuel efficiency: 34.3 miles to the gallon on high way. The improvement is 3.3-3.9 miles per gallon compared to Mobil1.
Interesting. I've been using Valvoline synpower 5w30 since 5k miles, currently almost 75K miles.
on both my current 1.8T VW'S i use Valvoline Synpower 5w-40 Full synthetic- it's an oil that is approved by VW...and has all the right cleaners/additives in it.
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......
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.
Just go out and buy Valvoline SynPower 5W40...
