amalysis with my supplying the oil. How does this compare?


I Buy my filters 8 to 10 at a time from Aircraft Spruce.
Get my oil from Sam's Club a case or two at a time.
Change my oil every 50 hours or there about. Every other oil change I send the
oil to the lab cost about $10.00
Also have my AP do a compression check at 100 hours. $40.00
I think that $110.00 is a lot for an oil change, but then it denpends on the
labor rate of you AP.

$110 is ridiculous, do it yourself, it ain't rocket science. Mine costs
$18 total for 9 quarts of oil. I don't have a filter and only do the
screen at the annual.
