Yes, I have an updated cover on it. I put a new Dorman cover on mid-way through this last interval (that of which it did use about a quart). I'm interested in watching it during this OCI if it'll consume or not.

My Tahoe I have the latest GM cover on it and it consumes nothing at all beyond maybe 3/8" in a small catch can. No noticeable drop on the dipstick.

Also wonder if the Dorman cover sucks or if it's fine? Reviews online sounded like it curbed consumption for folks like the latest GM covers... the Dorman ones looked to have a similarly shaped PCV hole in the baffle.

Work was done at a Valvoline quick lube. She brought the car by because she had oil in her driveway. Found the old drain plug to be stripped and leaking. Oil was at add line so not low. She had the oil changed about month ago.

Subaru had a problem with that design of drain plugs. They updated the plugs to P/N 32195AA021. I believe the botched plug in the Ascent used a 14 mm hex socket. The upgraded plugs use a 17 mm socket. The new design is stronger and the socket is able to bottom out on the plug hex head. The thread dimensions are the same. Many folks have had issues with the type of plug in your picture.

This is not an excuse for the slimy work done at the oil change place, however.

Edit: This tool set is wonderful for taking off rounded plugs.

Left the Champ P1009XL synthetic cartridge filter in for another 6K, I get two OCI's out of these.

Changed the engine air filter (about 20k on it) and rotated the tires as well.

Yea I just went to the parts store got a replacement plug. It was 17mm. It looks like they used a hammer and screw driver to tighten it back up.
