- VS11 Statesman
I have both a VRII comm. & a VSII Statesman with the ecotec engine.
So many oils on the market now. I thought as a general rule that older cars say pre 1990 needed 20/50 grades whereas newer cars needed something closer to 15/40- but the VS manual says to use a 20/50 oil.
Any thoughts? not looking for an expensive high performance oil just an everyday good qlty one say GTX2 (20/50) or GTX 3 (15/40).
which is the best grade for the VR & VS models?
