- well, AD oils have recommended changing for non-filtered aviation engines at 25 hours and for filtered at 50 hours...in 50 hours at 100 kmh i can ride 5000km-i change my oil about every 2000km
- ''Keep in mind that piston driven aircraft engines operate at low rpm,typically under 4000 rpm,have low comp ratio,low power output per cu.in., and operate with very low valve spring pressure.the oil requirements would probably be lower than a race engine.Bill''
- also aircraft oils are designed to operate with large internal-external temp differentials
- i imagine that aircraft engines will typically operate at more consistant revs than motorcycles where traffic and shifting thru the fearbox will produce a range of revs
- naya, personally i think that if you get the oil cheap and regularly change it youre not likely to have problems...you could always take a sample and do an oil analysis-the result could be rather productive...this is only an opinion, not advice...an interesting question
