I switched over to Amsoil full synthetic 10W40 at approx 7000km and it's been great. The engine temp runs a few degrees lower than before and the trannie is alot smoother. :thumb:Hellfire666 said:Should I be running synthetic oil in my 954? It's broken in now(7000 KM), what kind of difference is there between synthetic an normal being used?
Any special types of good synthetic?
