All engines burn a little oil (even piston engines burn oil at about a 1 to 400 ratio to gas they burn)
But if you're leaving a small cloud of oil smoke behind you every time you pull away from a stop sign, then it's best not to shrug it off as the idea that rotaries are just designed to do that - because they're not.
You should always examine any car as harshly as possible, as though you're bringing a new member into your household, after all it is your hard earned bread you're paying with - with any Rotary powered car it's good to be even more critical.

Rotary engines are made to burn oil to keep the apex seals lubricated, significantly more than a piston engine.

[2strokebloke]

Yeah, and 2stroke engines burn even more oil than rotary engines, and even with them excessive smoke after the engine has warmed up is a sign of internal wear, and shouldn't be shrugged off.

Yup, Rotary IS supposed to burn a little oil. This is how it lubricates! Rev that thing up to 10K!

yea smoke is deffinately not good, not for any car/engine that I know of, but lets stop talking about oil already
