Someone had told me that I should run the green stuff because that's what came in my engine from the factory!? Is that true? Does anyone know?
My owner's manual (2004 model) says the car came with 0W-30 and that is also what it recommends once the factory fill is replaced. I don't know about other VAG models or model years.quote:

John.
I've done the internal mental debate you are going through.quote:

I know when i bought my 00' golf (one fo the few german made golfs) 1.8T in the summer of 03', i pulled the dipstick on a golf 337 and found a beautiful GREEN coloured oil on the stick! i doubt it was in fact, GC (SLX) that we know and love, but im sure that its actually like a green coloured 5w-40 or the low HTHS vis. SLX (maybe?)?
Im about to drain my GC in my 1.8t after 6K miles (may be 7K i didnt write down the exact mileage at the last change-DOH!!) and send off for analysis. The past two i was told to go at least 7K. But, that was on stock boost levels (150hp 5-8.37psi). But, now im running 10-11psi peak and about 8 average via a $30 Manual Boost Cont. Anyways, we will see just how well this oil protects the VAG AWD engine when the boost is turned up. Im sure itll do just fine though as the 225hp TT engine specs this oil-right? (503.01 spec?)
Lastly, almost went with BC 5w-40 instead and i prolly will if this GC sample doent come back as good as before-summer heat is comming and my turbo gets hot! I still think that the BC is a real syn oil but im in the minority. The back of the bottle does worry me that its a syn blend however as it says-"Offers Full synthetic performance...." May be a clue.
have a good day!
