Lucas Oil 10W40 Semi-Synthetic Racing Oil

Semi-Synthetic SAE 10W-40 Racing Only Motor Oil

As oil temperature increases, viscosity decreases. The best way to combat this problem is a higher viscosity, thermally stable engine oil that can perform consistently at the elevated temperatures required when racing.
