Here's something that is being kicked around on our Beechcraft list. Someone originally asked about a particular engine additive. Mike Busch (The Saavy Aviator) never heard of it, but someone else did. Sooner or later it will come here, so I thought I'd post it.
"Mose" has a shop in MO., and is a 30 year veteran of Continental Motors on it's technical side. Just want to throw that out for those who like to play devil's advocate. I take this guy's word from experience just as if it were the Gospel According To St. Fred. In other words, save your money. ----- Original Message ----- From: "Bob Moseley" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, October 17, 2008 9:57 AM Subject: B: Re: AVlube oil additive > Once upon a time, long long ago, there was an engine additive that was > claimed to add hours, less wear, extended valve/guide life, less piston > scuffing, longer bearing life, increased libido, decreased hair loss, > weight loss, increased muscle mass and a few other things.
