Have a quick question.... I have been running 30% nitro in my B3 since I bought it. I just realized today that I will not have enough fuel for a race and if I order it, it wont be here in time for the weekend.

So, my question is...... I have some 20% out in the shed, if I use this how is it going to effect my engine due to me using nothing but 30% for break in and normal running?

Thanks for the help!!!!
