    I do it also, but does 50 hours or so seem like a very short interval for changing oil? I know the engines co. recommend this, and so I believe them/do it. The reason you do oil changes is to get rid of the oil "used up" oil right? If so, wouldnt it seem like this oil is capable of more than 50 hours of use?

    Does anyone know the operating temp. of say a 27 pony kohler air cooled? My only idea is than these engine run far hotter than car engines, and the oil breaks down faster. On the right track?

    PS- I agree that 5 bucks in oil every once in a while beats the heck out of 2k for a new engine!

    100 hours ... amsoil synth.

    if amsoil recommends 25,000 miles in cars.. there is no way it wheres out in 50 hours lol.

    its about the dirt/dust our engines are subject to. and for that reason, i think concentrating on the absolute best air and oil filtration is the key to using these oils potential

    I use Wal-Mart oil and change it every 25 hours or once per week. But, I only change the filter every 200 hours. I've got 2500+ hours on a Kaw 23 with no oil related problems.

    why would you put fresh clean oil in with a dirty oil filter?
