Because rotary, actually Wankel, engines consume oil like a two stroke. It's a total loss lubrication system. Oil is injected with the intake charge and then lubricates the rotor and housing. For once the dealer was being honest.Like Highbeam, IMHO, for fuel economy the required viscosities are getting quite low and this could contribute to oil usage. I remember a friend with Mazda rotary went through a quart every 1000 miles, he was told that that was normal.
