So I'm just about ready to get my 1987 Turbo II back on the road with a clean rebuilt motor, i decided to remove and OMP after reading https://www.rx7club.com/2nd-generation-specific-1986-1992-17/premix-compressor-822161/ and seeing the advantages and disadvantages of this set up. I hear the reccomended ratios are 1:100 when using premix however I came across this premix while looking for parts to finish the project up.

"Idemitsu Racing Rotary Fuel Lube (Premix) - Synthetic Blend
Inherently with many rotary engines, the entirety of the rotor and housing are not being sufficiently lubricated, resulting in premature wear or damage. In order to increase lubrication within the engine, Idemitsu developed Idemitsu Rotary Premix. At 1/2 oz per gallon of fuel, it is a cost effective way lubricate more of your engine and prevent premature catastrophic damage.

A special blend of base oils reduces deposits and subsequent exhaust port clogging. As a result, your rotary will maintain the power at which it was designed. Special detergent/dispersant additives keep your fuel injectors clean to reduce maintenance. Provides additional lubrication for apex and side seals to increase seal life and increase efficiency of engine. Special additives allow for better sealing of the chamber, creating greater efficiency and more power."

It specifies "1/2 oz per gallon of fuel" for use

1 US gallon = 128 US fluid ounces

so it would be 1:256 ratios is what it reccomends

What im getting at is if i used this product at 1:100 ratios would it be a suffecent lubricant for my engine? if not what brands have you used in your cars that have no OMP and use premix?

Thank you for your time in reading this and advice.

 

Mazdatrix recommends using the 128:1 ratio with the Idemitsu that most people without OMP's are using.

IMHO, 256:1 is too rich if the OMP is active.

 

yeah, pretty sure the recommendation of 1/2 oz per gallon is assuming your omp is still functional. go with the 100:1/128:1
