I use TCP in every tank of 100LL and also 4 oz of Marvel Mystery Oil for every 10 gallons
 
I have no idea if it works but I have not had a valve stick sine I started (about 9 years ago).  Prior to that I had a valve stick on me twice

Subject: [COUPERS-TECH] ercoupe on 100LL

Pardon my ignorance on the topic, but I have been lost in a time warp out of aviation for a dozen or so years and am just returning so this issue may no longer be germaine. But when I was leaving aviation, 100LL was just being phased in and 80 octane aviation fuel phased out. I remember alot of problems for 80 oct. engines when run on 100LL. There were several fuel addatives on the market that were supposed to solve the problem. Has this issue been resolved or is it still a problem. My plane has the 85 hp engine and the mixture is wired full rich. Is this something that is an issue in this regard?
 
I understand auto fuel has been possibly nicer to older motors like ours but the airport I am based at doesn't like people using autogas for obvious reasons and I really don't care to create a problem. But then again, what works in the motors? Is 100LL a problem?
 
thanks
