How reliable is a Rotax engine?
Pros: robust and reliable according to rotax themselves, the ideal engine rebuild interval to ensure reliability is 40 hours, which, compared to iame and rok which have an engine rebuild interval of 15-20 hours, does not even come close to the rotax’s reliability. Xps full synthetic 5w-50 aviation engine oil was designed specifically for rotax aircraft engines for the best performance, reliability and safety. Over two-years’ worth of development, forty tested variations of fluids, 20,000+ gallons of aviation fuel and 12+ fired engine tests led to the final formulation.These engines offered high thrust to weight; albeit,at the expense of fuel consumption (a typical Rotax 503 or 582 burns four gallons an hour of automotive fuel at cruise power), and they offer less reliability than four-stroke engines.With record-setting performance, superior fuel efficiency and proven reliability, Rotax engines define the industry standard in every category. Every model features the industry-exclusive Closed-Loop Cooling System to keep corrosive salt water and debris out of your engine block for unbeatable peace of mind.With record-setting performance, superior fuel efficiency and proven reliability, Rotax engines define the industry standard in every category.
