C145/O300 Endurance/Reliability

Post by GAHorn »

It’s pretty amazing these old engine designs we’re flying behind when you think about it. No oil changes, no spark plug cleaning (and on leaded AvGas too!), no magneto mx.

As early as 1949 records were being made by this engine, 75K miles and 6 weeks (1008 hrs):
1949
1949
And that record was broken yet again ten years later with a flight that lasted over 2 months, which was almost a Full TBO flight without any oil changes* or service (1558 hours):
1959
1959
I once missed a timely oil-change by almost 30 hours. I don’t feel so bad about it now tho’.... despite having a spin on filter, I still shoot for 25 hr oil changes despite Continental allows 50 with a filter and 100 before the filter itself is changed. I always change filters as well at the 25 hr oil changes. I simply cannot believe its a good idea to run clean oil thru a dirty filter. YMMV

* The Hacienda airplane did have an outboard motor fuel tank filled with oil which was periodically pumped to the engine to replenish oil consumption.

An originality nut (mostly) for the right reasons. ;)

Every time I pass by the LAS airport, I stop and stare at this airplane and pay my respects to the airplane and crew that flew it. Its hanging from the LAS Terminal Roof by the Spirit / Southwest terminal.
