Spark plug analysis

    For all the people I know and classes I've been to it's with either fuel. I personally don't see a reason to go over 100 hrs. It's up to you.
    I look at plugs as the heart beat of the engine, the oil is the blood. Neglect either and they may become deseased like a persons body and go downhill.

    Good point. Do you have the same philosophy on oil changes? i.e. 25 hours regardless of fuel type.

    Hi Jim,
    25 hrs. for 100LL and 50 for auto fuel.
    The manual says up to 100 for auto, but again I don't know a single person who does that.
    My whole philosophy is to get to 2000 or more TTSN hours with no more than the prescribed general maint.

    Neglect part of the system and it may be felt in the wallet later or over some really tall inhospitable mountains. ?

    Hi Roger,

    I use AVGAS so I change oil every 25hours.
    Question is:
    It is necessary to change the oil filter every 25 hour or it could be changed every 50 hours.
