REFLECTOR: Oil, P-factor and othe things

[Andrew Ellzey]

I flew a Mooney M20E for 13 years, an it had an IO 360A1A it also used a qt of oil every 4 hours from the time it was 0 time till I sold it with 600+ hours. I found this formula in one of my Lycoming manuals, max allowable oil consumption for all Lycoming engines is .006 X BHP X 4 / 7.4 = OT/HR.

For a 200hp IO-360= .6486486 X 4hrs = 2.6 qts max

Hope this makes you feel better about your oil consumption.
