I always used to wonder how the car engines got away with so little oil but after my son got a car and I saw how they were used I think it's probably because the engine only gets to peak revs for maybe at most 5 seconds on a straight, after that it's all on again off again....blat...blat....blat
.
Strange thing is -- that this "on again off again" running is probably real bad from a lubrication perspective.
2-stroke engines don't like running on a trailing throttle because it means that the RPMs and a degree of load are still present but there's very little fuel (ie: very little oil) passing through the crankcase (throttle is closed) to provide the lubrication.
And just for the record -- I'm on about my sixth gallon of fuel blended with 12% Coopers oil and my engines are still "as new" too!
If you use a good oil, you don't need anywhere near as much as you might think you do.
