$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.

I'd recommend, just like my airplane service manual says, to check both the
pressure and suction screens at every oil change. Why? Well, I found a hunk of
bearing in my sump screen last oil change. Nothing weird on the oil analysis,
nothing weird in the pressure screen, engine was running great and has
excellent compression and performance with no sign of trouble. I'm waiting to
get the engine split open to find out the extent of the trouble. If it did
destroy a bearing, then maybe I just averted an in-flight engine failure. At
the very least, I might have saved myself buying a new crank.

Lycoming pressure screen gasket: $0.97
AN900-16 crush washer for the suction screen: $0.39

Case of oil: $30-$50 depending on preference.

Add $15 for a filter if you have one.

Should also check the gascolator and fuel screens while you're at it. Never
know when a hunk of fuel bladder or sloshing compound might show up. Sure would
make for a bad day if it clogged up.

$110 isn't out of line. $40-60 for materials and an hour labor to clean
everything, cut open the oil filter, wash down the engine with solvent, run up
and check for leaks, sign the paperwork.
