Quick Q: Why WOULD I use synthetic?

No matter wht the claims are about the composition of the oil new, by 3000 miles it's time to change - it ain't the same stuff that came out of the bottle.

you dont. so when you compare a typical piston motor to a 1.3 l rotory... that puts out as much as a 3l piston motor you are going to look like an ***...
so start with bobtheoilguy and get back to us...
