Racing Rotary Premix

Pre-mixing is recommended for all rotary vehicles — including those with a functioning oil metering pump. The OMP is a single point of failure, and the apex and side seals benefit from the additional direct lubrication that premix provides.

Idemitsu Racing Rotary Premix is formulated specifically for rotary fuel lubrication. Not for use with alcohol-based fuels such as E85.

Recommended Premix Ratios

• With OMP: 0.5oz per gallon
• Without OMP: 1–2oz per gallon

Formula

• Special base oil blend reduces deposits and exhaust port clogging
• Detergent/dispersant additives keep fuel injectors clean
• Additional lubrication for apex and side seals — increases seal life and combustion efficiency
• Special additives for better chamber sealing

Idemitsu recommends the Ratio Rite measuring cup for accurate premix ratios. Not compatible with E85 or other alcohol-based fuels.
