Stay with 10% Fuel or go with 15%

[Lt.Doomsday]

it was really a nice day up here so i ran the nitro car for 3 hours.
i'm almost done with the gallon jug of B.S. 10% fuel.now,since the R/C car is broking in should i step up to 15% fuel?

also,what brand of fuel should i use?

What are you running it in? Engine size and make?

I have been running trinity mhp 20% for about 2 years now. I've recently purchased some wildcat 20% because it has 14% oil instead of trinity's 12%.

I haven't used anything less than 20% nitro since I have started.

Engines I've used:
Dynamite Mach .15
OS .15 cv-r(x) (2 of them)
trk 2.5 (hated it, think I got a lemon)
OS 21 RG-X(P)
Omega 21 Comp w/pullstart.

This is over a 2 year time period.

You should be fine running 15%. You will gain more power (minimal) but you will be able to run it richer since the extra nitro will help with ignition. This will help prolong the life of the engine. At least in moderation. This is why I run 20%. Enough for a smooth low idle, but not to much to wear the egine out sooner.
