hi, can get "valvoline vr1 racing oil" cheaply. (30 bucks from repco atm) is this suited for a vs commodore ecotec? cheers
What's the viscosity of the oil and how many k's has the engine done? Edit: Saw the rating from the online catalogue, its a bit thinner (10W40) then what the owners book says (20W50), so you might get some leakage/seeping in some areas.
