Rotary fuel use at idle
 

I'm a bad rx7 owner. Gas prices have made me park the 18-21 mpg 1983 rx7.

I was thinking I could up my MPG using some ecomodding driving tips like
Coasting in neutral , engine on
or
Engine off coasting and bump starting the car.


Do Rotary engines use (Much)more gas than a 4 stroke engine at idle?

Will gentle bump starting the rotary engine while rolling cause any harm?

SC

bump starting is totally fine.

the engine will use more fuel at idle than a normal piston engine, the idle mixture is adjustable, so this can be helped a little, but it is still going to be higher than a normal piston
