To drain or not?

When I know the car is going to sit for more than a month or so we will add 110 octane race gas as a stabilizer. Race gas never goes bad as I have had some race cars sit for 10 years or more and start up with no problems.

Race fuel has an amazing shelf life. And it make the car smell so good too!

I run 98 octane in my 3W's with Redline 50:1 and always have someone ask why my engines smell different than everyone else. I love the smell of high octane and Redline in the morning or any time as far as that goes

I have never ran my gas engines dry only nitros. I use to drain my gas tanks but the tygon seemed harden quicker so I stopped draining my tanks and switched to Viton line in the tanks. I just leave the 1/4 or so tank of gas in there at the end of the day. So far I have only been flying twice this year and haven't had any starting issues. Both times were about a month or so apart. I'm using 93 octane ethanol free gas too.

No to emptying the tank and no to running the engine dry.

+1 on that!!! Something about that Redline vapor hitting the air that gets the adrenaline flowing for a good flight!!!

Quite a lot of good info here. I drain my tanks for odor control but never run my engines dry. The bit of leftover fuel in the system seems to keep all the rubber parts happy. Viton or Fluorosilicone clunks never harden. Very few if any carb problems but our local fuels seem better than some in other parts of the country about causing fuel system problems.

Classic cars and outboards get summer blend, 93 octane, non-ethanol fuels with zero problems. I never use fuel stabilizers as I have seen them cause problems in the past.

Summer blend fuels are far better then winter blends due to the highly volatile nature of winter blends.

Anyone with a classic car in the garage....the problem is the battery.

I use good fuel without ethanol. I use good 2 stroke oil in it. I leave the tank with whatever is left over from the last flight.

Pretty much my same routine.

I never drain.
Always keep about a quoter in the tank.
When I come to the field I just kill switch the ignition put the throttle on full flips the prop 3 times then I turn on the ignition put the choke on throttle on idle and start the engine in the same method you all do.
Works like a charm friends. Try it....

I always run them dry. I guess its just a habit. Never really had a starting issue. It might take a couple more flips but always starts.
