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.
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!
