Royal Purple
Max-Gear Lube 75W90

Royal Purple Max-Gear Lube reduces frictional wear and subsequent heat using an impact absorbing, non-shearing molecular structure suitable for both high performance and OEM applications. Max Gear will withstand the high temperatures experienced in race and cross country driving environments. Viscosity is comparable to 75W90.

Racing Beat has been recommending the use of synthetic oils in rotary applications for several years. Our research has found that synthetic oils provide superior friction reducing between sliding surfaces, reduced foaming, and lower oil temperatures. We have tested several different synthetic oils and have found that while most offered improved wear and lower oil temperatures, none offered any horsepower gains... except for Royal Purple!

Our in-house testing has yielded up to a 2% performance increase after changing from mineral-based oil to Royal Purple Synthetic Motor Oil. How could this be? Jim Mederer, co-founder and chief engineer at Racing Beat, was truly puzzled. With over 35 years of professional racing experience under his belt, he has seen and tried just about every "new" lubricant that hits the market. All offered better wear and lower oil temperatures but none offered any horsepower improvement. After spending time consulting with the engineers at Royal Purple to better understand the reason for the horsepower gain, it was explained that the secret was the proprietary ingredient "Synerlec". This Synerlec ingredient provides an ultra-slick film on internal engine components to significantly reduce power-robbing friction. Less friction equals more power!

Other professional engine builders have confirmed that Royal Purple Synthetic Racing Oil delivers measurable horsepower gains. Independent dyno tests show increases up to 5% (on smaller displacement engines) with nothing more than an oil change.

Give Royal Purple a try with your next oil change!
