Our 15W-40 Black Label Semi-Synthetic, Purpose Tuned Racing Oil (PTRO), is designed for engines running on methanol, ethanol and race gas.
Why is that important? Because the oil will protect against corrosion and pitting common with Methanol and Ethanol fuels. It also has capabilities of suspending fuels in an emulsion if fuel over flows into the crankcase.
As a bonus, this oil has the ultimate additive package to include a Tri-Zinc combination and our proven XL-1 Engine Treatment already built in. Just open and pour in, no measuring... it's just that easy. You will prevent valve train and bearing wear, get that extra horsepower and torque from your motor.
