Twinkie Oil Consumption

by **SLIMDREDGER** » Fri Oct 24, 2008 12:52 am

I haven't kept any precise figures, but I find that long flights result in lower oil consumption per hour than short flights and/or touch and goes.

I average about a quart of oil/10 hours/engine but feel that much of the usage is vapor out the crankcase vent. I always end up with some drip on the pans under the vent pipe after the airplane has been in the hangar overnite. Do others have this, too?

Hi Al,

I also have had or still have a few drops of oil on the floor. I posted on both forums a couple years back and heard about turbo leaks but nothing that got to the root cause of mine. I started to track them and watch the inside of the cowl when it was removed for annuals.

Finally got the source of one drip and that is my oil quick drains were old and seeping. Just put in new oil drains right before the annual/paint job so don't know enough if this fixed but I think so as the drain fittings have been dry every time I look at them.

The second source has been the vent tubes and they have a tendency to vent when the oil is topped to re-calibrated 6 - I'm still tracking this one but as long as others are interested maybe we'll hear more folks' experiences.
