You are pretty much at the lower limit of oil usage, according to Continental. I'll attach the form that shows it. When I had my engine overhauled in 2006 ir was consuming a quart every 3 hours, and that is awfully close to the limit. It also made trips a pain, since every stop I had to put oil in it.
Continental tells you to worry when oil is consumed 1qt per hour. They have a service bulletin that defines when/how to evaluate oil usage (oil analysis is imperative to actually know what's going on).
I put 8 oz of camguard in my engine every other oil change. On my Aircoupe and my C182.

How much Marvel Mystery Oil to add to the crankcase in a C-85-12F engine? My mechanic suggested using some to help with oil consumption which is now at about 1 Quart every 2.5 hours. High time engine but seems to be running strong. Any recommendations would help. I used MMO in several of my Bonanzas over the years but can't for the life of me remember how much I added to the oil. My memory of these incidental things has gone south since I turned 83 this month!!
As a side query, I wonder how many ERcoupe pilots are in the eighties and still flying their Coupes. Just curious. Thanks in advance for any and all responses. "Keep the blue side up!"
