I seem to recall that switching from one brand of fuel to another required a
new break in period.  So, unless you're going to stick with the same
approximate mix for the life of your engine, I'd say forget it and invest in
good fuel.

Also, make sure you run car fuel.

I think its probably a good idea actually. 35% is too much nitro for a car IMHO. 20% is
about right.
Remember to give it a good shake EVERY time you use it to blend everything that may have
settled apart (like the oils - they might not stay mixed)
and richen the engine a bit for a few tanks so the engine can get used to the new heat
characteristics.
Oh, and i wouldnt do this for an expensive race engine either just because ive never tried
it. Hell, i wouldnt even buy an expensive engine because im so hard on them...

Hello,

NO,NO,NO

It would be ok if you could control your mix by adding other stuff like OIL!
but your not doing that your adding to premixed fuels. One fuel could be a
synthetic oil the other may not be, You cold also be adding additives from
one fuel to the other not good. Also why would you want to thin out your
35%.....  I use 40% in my street tc3. I do how ever rebuild that engine 2
times a year. but that's the price you pay for performance.
