Engine oil VALVOLINE or AMSOIL
The oil comes out cleaner with Amsoil. I also notice much less oil loss/evaporation with Amsoil compared to Mobil 1 or anything I've used. With Amsoil the level does not go down at all.

Here is an amoil oil test in Acura TSX. The 43150 mile test is amsoil series 2000, the 34000 mile test is mobil syn blend. At 5700 miles amsoil contained the same 7 parts of iron, that mobil syn blend contained at 3000 miles in the previous test. Thus about 1/2 the wear vs mobil syn blend. Damn good oil.
I've used AMSOIL since 1977....in everything from to name a few, my 83 GTi, 88 Scirocco, 04 R32 and now the wife's 06 Passat 3.6L as well as my 04 Volvo S60R and have never had an issue. I use the 5w40 in the Passat and 0w30 in my Volvo.
I have used Amsoil's 5w-50 on my mk4 GTI 1.8T and my Passat from their first oil changes until now. I love the oil and use it exclusively.
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.
When I tried Amsoil in my 16v for the first time, oil temps were 10 degrees cooler on my MFA. I have Mobil 1 in now and my oil temps are back up 10 degrees higher.
same as most any other top quality synthetic, but a little better i blew 3qts out of my rabbit on its maiden voyage an drove for a few min with probably almost no oil pressure. no damaged bearings, no damaged lifters, engine still runs like a champ an that was almost two years an several thousand miles ago.
FYI, I was running Castrol 5w-40 previously, but the last two changes have been with Amsoil 5w-40. I could understand 5k intervals, especially for guys w/FI, or those who admittedly beat the hell outta their 24v, but dang... A lot of $$$ going down the drain here.
