But FWIW, I use a 50/50 mixture of any good TCW-3 oil and MMO in my fuel.  The MMO was selected for it's ability to keep seals from sticking in their grooves.  I have no idea what ingredient  is responsible.

Hi Tracy,

 

Interesting to hear you say this, because I had almost decided to do the same thing, purely because I can't find a consensus of whether TCW-3 or MMO was better.  I think it may well be the case that each has some advantages.  By mixing like this, you're using the MMO at nearly the concentration they recommend, and making up the rest of the 1oz/gal with TCW-3.  

 

I have to ask though, are you mixing these because you feel like the mixture (solution, whatever <g>) performs better, or because you like MMO, but realize TCW-3 is cheaper.  In other words, if cost were no factor, would you just run straight MMO? 

 

Thanks,
