With regard to TEL as a lubricant/Valve seat wonder-all that has basically been debunked, how is it that Petersen who does the MOGAS STC state that every 75 hours a tank of AVGAS must be run through the engine. Is this because of;
a) Petersen believe in the OWT.
b) Some officious entity made them put it in "Just in case"
c) it provides some other function.
If you need a quote re: the 75 hours, I'll dig up my documentation and post it, otherwise it might be on their website.
