will fuel injection cleaner harm the rotoary engine?
i bought the chevron pro-gard fuel injector cleaner
after i used it the car started leaking
and it said on the bottle not recommended for air-colled two-cycle engines is that talking about the rotary engine?

 

Air cooled 2 cycle is like a snowmobile.


But I don't think once in a while that fuel injector is a bad thing...just dont use that cleaner that goes in every tank...I used that crap on my Turbo II and it wouldnt idle until I ran some 2-stroke non-synthetic pre-mix through the gas.

 

Well, those cleaners are designed for piston engines. Piston engines can swallow quite a bit of harsh detergents and such, but a rotary engine has sensitive parts because it's a precision machine--not a reciprocating mess of parts!

Anyway, in conclusion, those cleaners have abrasive junk that will harm rotary engines. I, and many of the people here, will recommend using MMO (Marval's Mystery Oil) to clean the engine. Add some to your oil and gas, maybe pour some down the carb, and you're set!

Leaking what and where???
Being more specific allows us to help you alot better

 

the engine leaks
i think it is the gasket leaking
but after a while it leak less now

 

Leaks....er..what?

 

leaks engine oil

 

From the oil pan area? From the housing sections? From the exhaust manifold area? Where?

i think oil pan but not sure about it

 

Is MMO ok for FI cars (GSL-SE)? Because I don't have a carb to pour it down...

 

You can premix it in with your gas. Normal premixing ratio is usually 16oz of MMO per full tank (no OMP). Since you are only using it to clean the motor, I recommend you use either a 16 oz bottle in with the oil or 8 oz to a full tank of gas. I doubt the MMO will clog your injectors with such a small ratio.

 

i run GUMOUT carb cleaner in it all the time, keeps the fuel system clean and zippy.
