Adrenaline Pro Shift +4 was formulated for the toughest applications in racing. The formula is based on 100% pure poly-α-olefin (PAO) Group IV synthetic oil that requires a very small amount of viscosity improvers to meet the weight specifications. The infusion of our patented FR3 Nano Technology and additive package provides unsurpassed levels of longevity and performance while keeping the fluid cleaner longer and providing better mileage and horsepower.

Adrenaline Pro Shift +4 also provides increased oxidation and thermal stability, deposit and sludge prevention, reduced breakdown, longer drain intervals and higher wear resistance than our competitors.
