premix question

Junior Member
I have been running premix in my series 2 for years now, removed the oil metering pump when I got the engine rebuilt.
I just use 2 stroke oil, not specific brand and use 100ml per 10 litres of fuel I put in my car. Usually pour it in before I put the petrol in so it gets stirred up.

if this helps my s5 fc3s has no OMP and i'm running 100:1 ratio for standard day driving. thats 1oz per 1 gallon. but if i'm racing i run 200:1 ratio. Or 8oz a full tank.
some brands i use
Klotz R50 ($70 a gallon)
Maxima Smokeless formula ( 40 a Half Gallon)
be expecting to be spending alot more money for fuel! make sure its what you really wanna do cuz it is a hassle but is also worth it in my opinion. also my motor isn't stock but from all the research i've seen its all about the 100:1 ratio. hope that helps!

Then luckily I got into contact with forum user RW7 who rebuilt and ported my engine. He was cool enough to let me hang around and help with what I could and so I learned alot from that. Now it's 12k miles strong.
Other stuff I had to fix:
thermostat (obviously)
replaced non replaceable u joints.
replaced oil cooler lines (actually rw7 helped me alot with that)
replaced fuel pump
replaced fuel injectors
not to mention alot of small stuff
It's a tough car to live with as a daily driver (expecially being a not very welled sealed convertible in the very rainy state of OR), but I love it.
It's really only left me stranded twice (t stat and oil cooler lines)
...Well technically I drove a 99 saturn sc2 first, but I didn't own that.

I still having my OMP, but I add a splash of 2 stroke as a precaution (about 3-4 oz). I run about 8oz too if I'm autocrossing though.
Why do people take off a working OMP? simplification? weight savings? I don't really get it.

You say you engine is not stock..so is the Ecu not stock too?

a main reason is the benefit from 100% synthetic oil in the crankcase.
for those of you not aware, MAZDA's RX7 owner's manuals instruct for the use of mineral oil only.

My S4 TII (~325 rwhp) now has ~400 mile since rebuilt.
Only the slightest trace of exhaust smoke under heavy load.
Working smog pump, no cats.
Spark plugs are perfect.

Many have been running full synthetic oil in the crank case with a working OMP for years with no issues. Dogs still chase cats, the sky didn't fall and Lindsay Lohan is still a drunk. There are good reasons to support either side, but MAZDA's recommendation isn't one of them.

More important than what brand or type of oil is using the proper viscosity for your climate, changing it regularly, and at closer intervals than what you might be used to with a piston engine. Most rotarys have fuel dilution to some degree. And the design of the engine just tends toward a higher rate of oil contamination.
Search in the 2nd Gen. section using terms like synthetic, oil type etc. and read opinions to decide for yourself.

I have been reading up on premix. I was looking at the Mazdatrix website for the popular recommendation Idemitsu Racing Rotary Fuel Lube.
There is a big Note! Do NOT use with ethanol or ethanol based fuels!
I usually have no choice except E10 gas. Any comments on that?
I have been considering using 4 oz per tank with a working OMP.. Reading that I am now wondering. I have never had any issues with just the OMP in my 30 years of RX-7 ownership.

From your profile you have an FD, so you'll first need a standalone ECU. You can't delete the OMP...at least not properly, with the stock or reflashed ECU. Doing so will put you into limp mode. If you're not having issues with it, why do you want to delete it?

Indemitsu is one of those "magical rotary oils". I'm not aware of any reliable data that supports a cost of over $6.00 per quart...plus shipping. Marketing hype and crazy IMO. Especially since as you said, it's really hard to escape fuels with at least some ethanol. Just get any ashless 2 cycle.

Bought my first RX7 new in 81. Unfortunately it hasn't been continuous ownership, there was a marriage, two houses and two kids in between that FB and my FD. But I'm still proud to be able to go back that far. Feel like a pioneer in a way, discovering these cars before they were widely understood or appreciated.

I currently have a Apexi Power FC. I don't have any problems with my lubrification system, yet. I wanted to do the premix modification for the safety of my engine. I want to keep it in a good shape for a long time.
Is it worth it or i'm just giving myself a bad time ?

.....SOME owners remove the OMP and simply pre-mix 2 cycle oil in with the gas. This works the same and has the advantage of injecting cleaner oil and oil (2 cycle) that's desgined to burn more completely than crankcase oil. BUT YOU STILL NEED OIL IN THE CRANKCASE for those other engine internals.
Other owners keep the OMP, some modify the OMP to source 2 cycle oil instead of oil from the crankcase and still others, like myself, retain the OMP in stock form AND premix at a reduced rate. Point is, there are different schools of thought on it. When you have a better understanding of the rotary, search and make your own decision on what's best.
