Alfa GT 2.0 JTS engine oil
I have just bought a Alfa GT 2.0 JTS and I live in Sweden!
I love my new ride!!!
Before I had a Alfa 147 1.6 TS and had problems with the engine sounded like an diesel on low rpm´s, maybe caused by to thin oil in the engine (used 10-40W then).
My GT now has Mobil 1 10-40W semi-synthetic oil, at some website I see recomendations of 10-60W fully-synthetic. Some say 5-50W.
What is the difference What is best for my car, some help is appreciated please! I drive normal, no street racing!
