I didn't want to hijack the thread on 100ll so I thought I'd ask in a new one. So riddle me this... I've got 1 hour smoh on my lyc o-360. I purchased 10 gal of 100ll at the local airport for nearly $6 a gallon (could be slightly old) and filled it into the right tank. I then went to the local Texaco and bought 10 gallons of 92 octane and filled it into the left tank. When running the engine on the 92 oct. I get a mag drop of around 75 rpm, both sides. On the 100ll I get a mag drop of about 300 on the right and 400 on the left!! I'm using the original slick mags set dead on at 25 deg btc as per the overhaul manual. Any thoughts? I'd like the option of being able to fly somewhere and purchase 100ll without worrying about it. ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
