Castrol Euro 5w40 held up longer than m1 0w40 in the Audi 3.0t sc. The 1.4tsi took 5w40 as well. The 2.0t looks to fit right in the middle of the VW line up lol, you see a pattern here? The 5w40 will do well to absorb the turbo heat, viscosity is king, just change it every 4-5k. Oil pressure should be better too.
Also, I could have swore there was an article about how vw504 oil, which is very good oil, does not do well with ethanol. With Europe not mixing ethanol in their gasoline/petrol like we do. Anyone else confirm or deny? But right now the jetta has valvoline xl-iii euro 5w30 in the 1.4tsi, it's vw504 and came with 2 car washes at the express lube. Will have an oil analysis in a few months, 250,000km coming up.
