Oil changes?

Bryan Wood · #1 06-28-2005, 07:02 PM

Just wondering how often everybody changes their oil? How long would you comfortably go past your normal change if on a long trip? Example: You change your oil at 25 hours and it has 19 on it now. In two days your leaving on a trip where you expect to put about 12 hours on the tach. Do you change it early or wait? I'm a nut about changing oil in my cars at 3000 miles even though modern thinking states this isn't needed. Now in my airplane I can't hardly stand the idea of going over the 25 hour mark. Ughhhh!

Hey Bryan,

Data point:
I'm going to take Flash for some Idaho camping in a few days. I had 18.9 hrs on the current oil and I changed it for the trip. I'm going to put around 20 hours on the hobbs during the trip.

Best always,

The recommeded oil change intervals of 25 hours with a oil screen and 50 hours with a filter seems good to me. Now the time interval seems harder to meet, as 4 months fly by faster than I can put 50 hours on the hobbs meter.
I will let the time slide easier than the hours and I've noticed the oil doesn't look dirty til about 40 hours anyway. I change oil about 45 hours or so, when my hanger time and hobbs meter meet. Seems there is always a rainy day or bad weather to allow the oil changes.....but that said, if the weather is good and the tach reads 49 hours....I'm flying and changing oil another day!! I have a filter!
