Hi Gents,

I am not replying for the administrative personnel who may answer; however, in the past it was recommended to me for use. Personally, I burn car gas as the engine is much happier with this fuel and avoids a host of problems. (I have taken the Rotax overhaul courses and work with professionals who operate Rotax 912-914 series engines and we avoid using 100 so called low lead where possible.) To further answer your question, I believe the issue with TCP is largely environmental as it is harmful to the environment. (But not likely as harmful as the 26 billion tons of lead in our atmosphere....)

best regards and happy landings,
Ken

Another product to consider that is less dangerous and more environmentally friendly is Decalin Runup.

An excellent observation. I have cut an pasted a portion of the company's on-line advertising data. Of note, is the fact that it is not approved in certified engines....

For your consideration,

best regards,

Overview
Decalin RunUp is not approved for use in the engines of certified aircraft but it has the same active ingredient, Tri Cresyl Phosphate as our previous product. Lycoming clone users have reported very good results when using this product.
RunUp MSDS

Notes on using Decalin RunUp:

Some white deposits may be seen on the plugs and in the exhaust pipe during use; this is normal with RunUp since the lead in the fuel is being converted to non conductive lead phosphate. When no additive is used, lead oxide is formed. It is lead oxide which causes plugs to misfire due to its partial conductivity shorting out the plug. In addition, lead oxide tends to form in large clumps or clinkers whereas the lead phosphate is crumbly and if any is left behind in the combustion chamber it deposits in even layers.

Scavenges Lead in aviation fuel after combustion to prevent lead oxide buildup on valves but still allows the lead to perform the anti-knock function prior to combustion.
It is an excellent additive for auto conversions, where it reduces buildup on oxygen sensors and plugs. If you have to use 100LL, then this stuff is for you.
Prevents valve seat erosion from valve seat micro welding. It is equivalent to TCP (for experimental only).
Does not contain volatile solvents so it is safe to ship and safe in the cockpit. You can carry it with you for out-of-town airports.
Easy to use graduated measuring and dispensing reservoir built into the bottle. No messy syringes!
Tested and stable down to 0 degrees F.

You have my vote.
Decalin for me and my clients and many of the Flight Design fleet using 100LL.

dean at lockwood aero told me tcp is fine for rotax engine use with 100LL fuel. decalin has no proven track record yet for rotax engine use.
