I never used oil analysis when I owned my Skylane. I'm talking about what others do. :-) Matt |

With a car, sure I'd just keep on driving it. Oil analysis can't predict with any certainty when an engine will fail. In a airplane, I'd have it torn down and inspected. However, this is much easier than with most cars. A good aircraft mechanic can rebuild the top end of an airplane engine in the time the car mechanic is getting the accessories removed from a modern car. Matt |

To rebuild a small airplane engine costs about $20,000 and takes months. You don't want to do it unless you have good evidence that it is needed. |

I was talking a top-end. That can be done in two days tops. And a full overhaul doesn't take months. Where'd you get that? A good mechanic do do that in 3 days. And many folks get a factory reman and that takes about two days to do the engine swap. Matt |
