There are a couple of "little" things that no salesman would tell you
- partially because of ignorance "vulgaris", partially because of
common greed. Before considering to buy a car with a rotary engine -
at this point only Mazda makes them - ask yourself 1. am I willing to
run with a can of oil after my car and 2. Am I willing to replace the
engine more frequently than some others replace timing belt? If the
answer to both question is "yes" - go ahead, otherwise - run away. The
steel seals in the rotary engine tend to wear out in the grooves and
wedge thus damaging both the rotor and the stator so the engine cannot
be repaired. These same seals alow oil to penetrated the combustion
chamber thus assuring astinishing oil consumtion compareble with that
of a two-cycle engine that requires oil being added to gas. Also, two
other characteristics of a rotary engine that might be of interest: it
provides HUGE power output from a small discplacement but gas mileage
is obsene as well.
