I have a gas leaf blower that requires 40:1 oil:gas mixture. I have a 1
gallon gas tank premixed with this oil gas.

I'm thinking of buying a chainsaw (stihl) which requires 50:1 mixture. Do I
need another gas tank to premix with this ratio, or is it ok to just use the
40:1 mix? Or perhaps I could put 45:1 mix in both??


45:1 is close enough to both that it likely wouldn't ever be a
problem.

I always kept 32:1 mix around for dirt bikes and just used that in any
2-stroke power equipment that needed fuel. Now with what I've paid
for my Stihl trimmer, it gets Stihl brand oil mixed like they say. No
exceptions.
