Mike, the product to which you refer is "Decalin". I talked to them to see if they'd confirm their base is not alcohol. (If you read the description, it sure looks like alcohol.) They assured me it was NOT alcohol...but they wanted me to demonstrate to them I was not a potential competitor before they'd share their recipie. (I want to KNOW what they're mixing the tricresylphosphate with.... the label resembles alcohol.)
Anyway... I don't use Decalin. And I haven't used Alcor TCP for over a year now, as well. I lean aggresively. Yes, the plugs still collect lead deposits, which I blast away every 50 hours of operations and I hate it.
I wish we could get ordinary AvGas...without lead. I wish they'd let the purchaser select the amount of "lead" or "no lead" AT THE PUMP....just like the autogas people did for years at Conoco and Gulf stations.
Alas. They don't seem to care. I suppose it's because the gov't won't give them an expensive grant to research how to not add lead to avgas.
If you can get quality mogas that meets the ASTM req'd of the STC, without lead, and use it promptly and completely, so as to not allow any of it to sit for months in your airplane tanks....then that should be good enough for low powered airplanes like ours with metal fuel system components. I just (almost) never run my reserve-fuel completely out of my airplane.
(But beware that some hoses and gaskets and o-rings may deteriorate more rapidly than expected. Plastic floats may sink, and before long Kelly will probably come up with a yet another color plastic and mandatory service bulletin for their floats.)
