25 hours on the tach, no filter, regardless of calendar time. The next oil change is less than 1 month, 28 hours to OSH and back. |

Rich, I go strictly by hours too, like Bruce. I have a spin-on filter and have used AeroShell 15w50 since the beginning... 25 years. Engine still uses almost exactly 1 qt. in 25 hours, after 1300 hours. If I had to be down for a real long time, like maybe a year, I'd probably change it out. I do live in a nice dry climate. |

I use the tach, as well: every fifty hours. I have a full aircraft filter. I use one quart in 15 hrs unless I have done some aerobatics, in which case it throws some out. Then I get about ten hours to the quart. I maintain the level between six and seven quarts. |

I use the tach. I do change at 25 hours even tho I have a spin on KN filter. My mechanic asked me why and I told him I don't like what the oil looks like past about 30 hours. He said good enough. My engine is old and has some blow by. It dirtys the oil more than some. Cubes |

Thanks for the info . !  I think the majority do the tach/hobbs meter routine . I just wanted to check with my cell mates to see what they were doing . RB
