why no synthetic oil??
i've heard that you should never use synthetic oil in a rotory. Why, why, why? i was a quart low today and mobile 1 high mileage20-50 full synthetic was all i had so i had to put it in and the car has never ran that smooth can someone give me a good reason or put an end to the myth. if thats what it is??

I have been yelled at numerous times for running synthetic oil. It has to do with the fact that the rotary oil is designed to burn small amounts of oil. Synthetic oil is designed not to burn. kinnda clashes. I guess in theory the oil will gel up and build up on the Apex seals. im goingto rebuild my motor soon and will be abel to tell if there is any nasty buildup

basically your're right. Rotaries are designed to burn oil, synthetic doesn't like to burn, and when it does it turns to plastic 
that can't be good on the inside of your motor.

yeah, and i guess it clogs up the oil injectors, i used to run it too untill i was talking to someone and they told me that i should be running regular oil. so then i just used some mmo for a week or so and got all the **** out i could, and then i switched to regular. but yeah it is bad for your car.

here is what I do, pull the oil injection lines and block off the oil injection valve (bottom front passenger side of block) then you can run syn oil, but make sure to add oil to the gasoline EVERY time you fuel-up. the plus to this is you dont have to check your oil as often, you can run a better oil, and rotarys run better on low octane gas (80 octane is run on the chapion roadcorse car currently)
Good luck

Tennis, anyone
Think of it as a 2 stroke engine, where you have to premix the oil and gas, the rotory engine (not all ) have
to have oil drawn in with the fuel and air, to lube the
seals at the corners,the nikki's were designed to add
oil to the intake, so it sorta premix's. the synth, oil's don't burn as clean as a ,,,( is it ? ) a fossel fuel oil ??
maybe,,it's important to check and change/add new,
or clean oil, because if your burning old beat up (black)
oil, that beat up ****, is what is being injected in the engine,I try to keep the oil in my 7 ,,as amber as i can.

you can block off any rotary motor's injection system if you want to premix. however the guys at redline swear up and down that their synthetics burn clean and will not gum up in the motor.
being able to run low octane has nothing to do with whether it's a rotary or piston but what the compression of the motor is. ours is low enough that we can use a more potent gas.

OK guys,
This is straight from the Mazda engineers at Seven Stock this weekend........YOU CAN RUN SYNTHETIC!!!
Mazda tells you you cant because they designed the motors for approx. a 30k mile tune up........your plugs will foul with the cooler burning synthetic oils there for oiling the plugs.....nothing carbons, nothing clogs.....simply the plugs will foul in normal street driving over a period of time. I dont know about yall but I change my plugs about every 2hours of running time(thats autocross time).
This is straight from the factory!!!! They actually told us to start spreading the correct info on the net and tell everyone synthetic is the way to go!!!

don't quote me, but i believe it was the castrol synthetic that originally caused all the probs. honestly, at $8 a quart, synthetic oil can kiss my boo-tay. seeing as i change the oil every 2k miles, i don't see the benefits of switching.
