I have two new Evo's, the 26 and 35 GT's. I was reading the break in procedure and it says to run a 30:1 mix but it does not say for how long or how much fuel. Can anyone here clarify that? I currently have ~4 tanks through the 26 and the 35 is still unrun.

The 45cc engines are supplied with one pint of oil, sufficient for 30 pints of fuel. So let's say about 4 gallons of fuel for running in? After that, switch to 2.5% oil in the mix.

Thank you for quantifying the break in requirement. With the fuel consumption rate of this 26cc I should have it broke in in about 2 years so long as I don't fly anything else

You will see, that as it breaks in, the expelled oil turns from black to brownish.
