Description

Bio-Rotary™ Racing Premix is a premium rotary engine premix oil engineered specifically for the needs of rotary enthusiasts, racers, and performance builders. Designed to solve the three biggest concerns in the rotary community—proper lubrication, carbon buildup, and fuel compatibility—it delivers dependable protection for both naturally aspirated and boosted engines.

Unlike conventional premix oils, Bio-Rotary™ combines exceptional lubricity with built-in fuel conditioning and corrosion protection. It helps lubricate apex seals, rotor housings, and internal components while reducing deposits, keeping spark plugs cleaner, and supporting longer trouble-free engine life.

Compatible with gasoline, ethanol blends, and methanol, this advanced premix is ideal for RX-7, RX-8, and custom rotary engine platforms. It burns clean to help lower emissions, improve fuel economy, and eliminate the harsh exhaust smell often associated with traditional premix oils.

Renewable Lubricants offers the only sustainable, carbon-negative premix designed for high-performance rotary engines. Its advanced biobased formula contains no petroleum while delivering serious lubrication performance for street, strip, and track use.
