1/2 qt/tank is about 1 oz/gal or 1:128 which is honestly what most people run. Some say way more, some say less.

Personally I run Idemitsu premix at a ratio of about 1/3oz/gallon in the tank and I also have it injecting it through the OMP. That works out to 384:1 in the tank and whatever the OMP injects. I really should start to measure it.

I've done this before and I'll do it again...... lets look at the factory system

Think about how much sump oil that a rotary burns. These are pretty crude numbers but hear me out. A quart every 3000 miles is "normal," so lets just say that you're burning a qt every 1,000 miles becuase you drive around pretty heavy footed. Ok, so you're using 32 oz of oil every 1000 miles. How much gas are you using? How about 15mpg? Ok, so in 1000 miles you're burning 66.67 gallons of gas. 66.67 gals = 8533 ozs. So that equates to 266:1 of SUMP oil on the high side. Being a qt low after 3,000 miles is roughly 1:800...... think about that for a minute. The factory system will inject sump oil at a rate of 800:1 and some people are saying to mix 4oz/gal or 25x the amount that the factory saw necessary.

Now, some people will say that the stock OMP will burn a qt in 500 miles of heavy driving. Ok, so lets think about heavy driving...... how does 5mpg sound At 5mpg and a qt every 500 miles the stock system is injecting it at a rate of 400:1. Keep in mind this is still sump oil, not really fancy designed for the task at hand 2-stroke oil.

Run Idemitsu, follow thier rec's and enjoy. They rec 1/2 oz/ gal or 256:1
