Question rotary=2cycle? think about it

now hear me out before you start in on this idea a rotaty engine has oil and gas in the same place in the engine in order to lub it right just like a 2 cycle right. you know that your oil get deluted and thined after awhile with gas because of this. so say you used 2cycle motor oil in your gas it all goes to the same place and would help with the problem of oil consumption you could just use you oil in the pan for your turbos and then ther is little need for oil coolers becaus the oil is the same temp as the gas which would also help with temp so in theory this would solve some problems.

I would just like to know if any one has thought about this idea or better yet have tryed it? (it works in theroy)

This is the concept Pettit goes about, however they go about it in terms of the engine and the stroking, not the oil it burns. Even though they do sell the Protek

You use any TC-W3 certified 2 stroke oil at a ratio of 100:1 per tank of gas.

Most of the time they premix because their standalone ecu does not support the oil metering pump, at least I think thats the reason.

You are correct in thinking that the rotary acts similar to a 2-stroke engine, since it's producing power at each revolution of the output shaft (crankshaft in piston engines).

I think using only gasoline/oil premix to lube the entire motor would be bad, because gasoline doesn't lubricate as well compared to oil, right? You should still use regular motor oil for lubricating the engine, especially in a street driven car, running premix all the time would be more expensive, I think.

You can't do only premix for all lubrication. 2-cycle engines have needle rod, crank, etc. bearings since they don't use pressurized oil for lube. The rotary would have to be made like that (needle bearing rotor, turbo, etc. bearings) to do it.

isnt there 17 textbooks on this topic in the forum already?

anyway... tcw3. but it lowers the octane and it is bad if you put too much so i just put a tiny bit in the gas just to be safe from both ends. still cant find someone that sells valvoline, all i can find is castrol and even then they dont have much of it.

It doesnt lower the octane enough to really make a difference. Obviously you still need engine oil for your turbocharger, but using 2 stroke oil for internal engine lubrication is better than using your engine oil. Engine oil doesn't burn as clean as 2 stroke oil. All this information is covered in that thread.

A rotary is a 4 cycle motor to address the title of your thread.

How's that? In terms of combustions per revolution of the output shaft, it's more like a 2-stroke.

If you look at the actual cycles of intake, compression, power, and exhaust it does all four instead of having the intake and exhaust happening at the same time. That's sort of the idea.

HEY! I was born in 86 too. My parent's are not stupid, I paid for most of the car, and I don't think an FD is a death warrant, at least to me

In any case, the advantages to premixing is that it burns cleaner meaning: A)spark can be more efficient resulting in slightly better gas mileage which can outweigh the cost of the premix and B)it doesn't leave as much carbon in the engine (ever open up a premixed engine compared to a stock omp?).
