I am thinking of putting Redline oil into my GLI. I had good luck with this oil on my last GLX.
From their website:
Our 5W40 engine oil provides for quicker lubrication and easier start-up. Reduces turbo lag and provides more power and economy in a properly functioning engine, while providing 25% thicker oil films than a petroleum 5W40 or 10W40. Recommended for many late-model European vehicles and as a factory fill replacement in many newer VW, Porsche, and Mercedes Benz applications.
That sounds good to me. Any suggestions or thoughts?
I think I have decided to go back to the Castrol Syntec that my dealer uses since I am about to hit 5,000 miles and have care-free maintenance. I don't necessarily think one is better than the other anymore and I think I would rather have the piece of mind that my warranty won't be voided.
