Alcor - TCP Fuel Treatment - Quart Can - Part Number : 73104
Keep your investment in top shape with Alcor's TCP! Since the shift to 100LL fuel for low-compression engines, Alcor has been a leader in providing pilots a fuel treatment to prevent engine fouling caused by lead. TCP is the only FAA-approved aftermarket product of its kind; a single dose with every fuel fill-up helps tackle lead build-up on valves and spark plugs. (Recommended dosage is 1 oz. or 30 ml of TCP for every 10 gallons of leaded fuel). Get dependable protection and better engine performance with Alcor's TCP fuel treatment.
The TCP Fuel Treatment Syringe (p/n: 73138) is sold separately
DIRECTIONS: For best results, use 1 oz. for every 10 gallons of 100 LL avgas. The dispensing syringe may be used to inject the desired amount into the gas tank. Tightly reseal the cap to avoid leakage. Dispose of the container properly. Do not reuse or recycle containers.
FAQs
Q: What is TCP Fuel Treatment and what does it do? A: TCP stands for tricresyl phosphate which is an effective tetraethyl lead scavenger. During the combustion process, TCP chemically converts TEL to lead phosphate, which is less conductive, thereby reducing spark plug fouling. The use of TCP does not impact the power provided by leaded fuel.
Q: Is Alcor’s TCP Fuel Treatment FAA-approved for use in aircraft engines? A: Yes, TCP is approved for non-turbocharged Continental®, Lycoming®, and Franklin engines. Other engines such as four-stroke Rotax are also reported to benefit from using TCP, but as of now do not have approvals.
Q: What is the suggested method for using TCP? A: TCP is drawn through a syringe and injected directly into the fuel tank. One ounce treats every 10 gallons of 100LL Avgas or other leaded gas.
Q: Why do I need a syringe to get TCP out of the can? A: The syringe is required to mix the correct dosage while minimizing potential spills, which may cause damage to painted surfaces. The can contain a filter to ensure that no contaminants (such as rust or can sealant) are drawn from the TCP can and injected into the aircraft fuel tank. If the syringe becomes challenging to use, properly dispose of the used syringe. Replacement syringes are available for purchase.
Q: Will TCP damage the rubber bladder tank, sealing compound or fiberglass tanks in my aircraft? A: No, as the concentration of active ingredients is very low.
Q: Is there a shelf life for TCP? A: TCP will last several years, providing the can is kept sealed and that the can is stored under conditions that minimize rust.
Q: I have an auto gas STC for my airplane. Would I benefit from using TCP in my plane? A: TCP is mainly for scavenging TEL. There is no data on the scavenging abilities of other compounds.
Q: Why does the label read “Do not carry aboard aircraft” and “Store can upright at all times”? A: TCP is a hazardous substance and must be handled with caution. Emergency information is on can labels and on the Alcor website.
Best priced around great and speedy service!
Also is the better of the 2 options since it is rated at 5,000 psi, not that I go to that high of pressure but I like the safety and security knowing that my chances of it blowing up in my face are a whole lot better and I can also purchase replacement seals for them at the same shop!!!
I bought the DC PTT because I know and trust the DC quality/durability to hold up to using every day. And so far it’s the best PTT I’ve used. I have a couple other no-name PTTs and the cable sheathing is crumbling and falling off. The DC PTT has worked even in sub zero cabin temp conditions when I didn’t have a functioning heater. I bought two to have a spare but the first one has been working great for 300hrs so far.
