O.k.

I'm getting into R/C again, after 10 years....I have some 5 year old redmax 12% syn-cas blend.....It's more yellow than red now and some evaperation has accured from a hole in the cap. Is there something I can split this with or should I chuck it?

I'll be running 40 size engines that are going get the once over before they hit the air.

I'm sure I'll get lots of dead stick time in, I just want to do it less than more.
