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.
TCP is the only FAA approved product of its kind.

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.

Required TCP Applicator/Syringe sold separately:

TCP Fuel Treatment Applicator/Syringe: Calibrated for proper dosage of the number of gallons treated for 100LL grade avgas (required for use on the Quart bottles).

No problem with Alcor, it is highly recommended for low compression engines to keep the led in 100ll suspended (less plug fouling)

My aircraft has a Continental O-470S1B engine which was certified as an 80 octane engine. I have been using TCP in my engine for 27 years since 80 octane fuel has not been available for several decades. My engine runs very smoothly and I havent had a problem with lead fouling while using TCP. Every time my plugs are pulled, they are very clean with minimal deposits. I am convinced that the smooth operation and longevity of my 80 octane engine is due to my use of TCP fuel additive.

Expensive, but does help keep the plugs (massive electrode) from fouling and easy to clean.

This product reduces chance of lead fouling and heat stress on cylinders due to lean burn setting on mixture control.
