'Tom et. al.

I was encouraged to use it in my Warner 145 - When I bought my plane, the field at which it was based had 80 octane, and the owner did not have to use TCP. I talked to some folks who suggested using the TCP lead scavenger since I could only get 100LL. I did -- for a while.

In addressing a leaking oil seal with the starter on the back of the engine, I talked to Al Ball at Antique Aero Engines in California -- I mentioned to Al that I was using TCP to take care of the lead isssues --- he about screamed "don't use that sh___! His comment was that the bronze and brass parts in the old carburators and in the engine are 'eaten' by the TCP and it will damage those parts of your engine.

Summary was 100LL is OK -- use Marvel Mystery Oil in correct or slightly rich amounts. Auto fuel is better.

I have two open cans of TCP I no longer use.

'Old engine users,

Old Engines want that lead! Lead is a lubricate and anti-Det. I agree 100LL has to much lead compared to 80 Oct. so clean your plugs a little more often. Why they call it Low Lead beats me. What the old engines don't like is the higher octane. Burnt, warped valves and burnt seats. I myself hate auto fuel, the smell and the chemicals. When it eats the bottom of my shoes, I'm not going to put it in the engine I sit behind. I do sign off on the Auto Fuel STC's for my customers. Read carefully the STCs esp for the Warner. You must run 100LL every five tanks to recoat the valves, guides and seats. I suggest running 50/50 combo with Marvel in the Eng oil and Fuel. The Ranger in my F24 has been running on 100LL for the last 300hrs, so far so good. I will deal with the damage later if there is any. In the mean time waiting for the new 87UL, its a coming.

'Tom, I use it all the time only because the guy I bought my 46 F24-w (165
hp) from said to do so. I use 100LL. I guess it works. I got my last
gallon from Great Atlantic Aeroplane Co., at Sun'n fun. 888-453-2376
Good luck,

'Good input -- one other note 75/25 auto and 100LL is about 80octane lead -- Using marvel also effectively lowers the octane.

I am very interested in some of the 2-stroke synthetic oils -- no gum for the carb, but real lube for the top-end. Not at chainsaw levels, but at something lower...I need to call a petroleum engineering friend of mine.
