CD 2 LEAD SUBSTITUTE

[FrankP]

Does anyone know about this product???
I have a news four stroke dipper lubricated engine I want to use it to provide extra lubrication.
Does it harm catalytic converters?

LOL! Why venture into that arena? Do you have a leaded engine that needs lead substitute? The question is, WHY?

leaded substitute is meant for non-stellite valve seats (on leaded gasoline engine) to reduce the erosion due to the lack of lead. It's not meant for use in all unleaded gasoline engine and there's never a guarantee if it ever upsets the emission control systems on later cars (afterall: leaded gas engines are never emission-controlled other than a PCV valve). Also: there is never the mentioning of UCL properties in any of these lead substitute additives so why would you even wanna get yourself into that part?

I thought it might be useful in small 4 stroke engines without catalytic converters to provide extra protecton

 

[Quest]

other than valve seat recession reduction (on non-stellite seats), there is no benefit running lead substitute additive(s) even on non-catalytic small engines.

OK now, mean no disrespect. Are you all over the board when it comes to OTC additives?

*curious*
