Overview

Since the introduction of 100LL as the main fuel for low-compression engines, Alcor has been a leader in providing pilots a fuel treatment that eliminates lead before it can cause fouling.

For use in Non-Turbocharged Continental, Lycoming and Franklin Aviation Engines.

A simple one-shot treatment with every fill-up prevents lead build-up on spark plugs and valves.

Rely on the one-and-only Alcor TCP Fuel Treatment for a cleaner and smoother-running engine!
Available in Ready to use Single Quart containers.

I was skeptical when I bought a Stinson with a Franklin engine and was introduced to Alcor/TCP. One look at the plugs at annual and we started using it in a Cessna 150 with an O-200. You simply cant believe how clean your plugs are after 50 hours of burning 100LL.

I have used this product for over 30 years. Keeps the plugs clean in my O300D. I did like the gallon size better.

I was having detonation issues (up to 3 times) after pulling the mixture out when cutting the engine in my Continental E225-8, almost embarrassing. My mechanic asked me to start using this product and upon the next flight, then engine did not have the pre-ignition / detonation occurrence 3 times. I use the 30 ml to 10 gallons and have used about 3 times thus far and it seems to be working as I barely get any spit or sputter after pulling the mixture. As current, I will keep using this product and currently I definitely recommend as it seems to be helping quite a bit and I do not see any negative to engine temps, exhaust gas temps. Very pleased so far. 9/1/2020

Im convinced this stuff works. Dramatic reduction in lead oxide on the spark plugs at annual time.

TCP has been very effective in reducing spark plug leading between annuals on my Continental 0-200 engine. The price is higher than I remember paying in the past. I hope you can negotiate lower prices in the future.

It will prevent deposits but will not clean whats already there.
