first let me stat that i just got a 88 rx7 gtu and i would like to know what type of motor oil would be best for my car. second as i live in the cincinnati area i would like to know if anyone here also lives in the area and knows a mechanic in cinci that knows rx7 motors and can do a good job on a tune up. last, how much gas is a tuned up tip to shape motor sposed to go through? miles per gallon stuff

 

i have penzoil 20W50, it's great stuff, makes oil pressure higher. just use that. Rotary engines suck gas, but apparently they are supposed to get like 17/18 mpg but most of us get around 14 i guess. Around 450 KM a tank

 

i have noticed that they suck gas. are you sposed to use synthatic or regular ???????/

 

some say synthetic most say "regular", use the search option this has been discussed many times

 

regular castro gtx 20w50 for me all year long, but i read some where that you may want to use 10w40 during the winter if your winters get below freezing (something like that)...
as far as gas goes, i get about 12-15/25 city/freeway
