Status: offline 		Glad to help! Yeah, I bought 5 gallons of the clean gas to stock up. And then I used 3 gallons of it for my other lawn powered engines because the DLE doesn't use all that much.

There are some guys in my club that buy the blended gas and then add water to it to remove the ethanol. It actually works, but it can be messy! I’ve never done it myself, other than a 3 oz test in a mason jar, so Google it for complete instructions if you want to try it.

Thanks for the great link to "clean gas" stations.  There are a few listed that are not too far from me.  Given a choice, I will use regular gas without any methonal added in my DLE 20cc.  


Very small distinction for several posts in this thread
Methanol (CH3OH)  is the primary component of glow fuel.
Ethanol (C2H5OH) is added to gasoline.

Thanks for the correction on the fuels.  I meant to say Ethanol when referring to gasoline and instead wrote Methanol.  I'm either too new to gas r/c engines or it's an age thing!

I'm definately a newbi with gas. Please pardon the question below if it's been covered already.

A club member suggested using white gas Coleman fuel instead of gasoline from the pump. I tried it just for the heck of it and my elderly Zenoah 26 seems to like it just fine. Yes, it's expensive (but less than glow fuel), but my friend says it burns cleaner with less carbon build-up, etc. and offers a higher octane level (more power).

I know just enough to be dangerous. Any thoughts, pro and/or con on running this fuel with my shiny new (and as yet unpackaged) DLE 20?

Some helicopter pilots swear by it. A guy at my club adds 10% white gas to his pump gas.

I haven't seen the need and pump gas works just fine.

You just have to get past his gruff exterior Unfortunately he's not on here any more because some just could not handle his blunt truth ( read his sig line) I have the DLE 20 and just use reg gas and a good 2c oil mixed at 32:1 and don't follow the Tower Hobby instructions.

Status: offline 		raptureboy - agree with you on gas - regular gas works fine in these engines, plus that's what the manufacturer recommends.

I cannot, however, agree with you on TOM. The reason I and. I'm guessing, some others had a problem with him was not his take on "the truth", but was, instead, his unnecessarily condescending and antagonistic presentation. And I dont' think he was kicked off of this thread - maybe he felt he wasn't welcome.

Most high performance engines / race cars etc have high compression engines. The high compression requires a higher octane fuel. This may be why some associate high octane with more horsepower. Lead was added to fuel to increase the octane, but nothing about the lead will add horsepower.

Thats true. faster burning gas leads to knocking. That is why you can't run 87 Octane in a high compression engine, it would detonate before reaching TDC and can cause severe damage to the piston, conecting rods or crank.   This is also why running higher octane in an older carboned up engine is needed, the carbon holds heat so the gas would ignite too soon, before the spark occurs.   You can run high octane in any engine, but you cant run low octane in any engine. Well you could, but it would run like S***.  

Will it give more HP? Only if the engine you run it in is designed and programmed(tuned for the old school crowd) for it.   My Ford Flex with Ecoboost has sensors that monitor the gas and can detect if Premium is in there and adjust accordingly. You can feel the difference going from 87 to 93 within a few miles.  It wil also detune itself when you go back to 87.  It is designed to run on 87 Octane, but is programmed for higher too.  It also uses direct injection which eliminates a lot of the causes for pinging, knocking and detonation by mixing the fuel in the air chamber at a precise time, and not in the intake manifold like general induction engines. 


The Coleman gas is actually Naptha and not truely a gasoline.

So for my 20, 30, and 50cc gassers there's no effective difference in performance between 93 and 87 octane? (not that the additional cost matters, but it WOULD be easier to fill up my 1.25 gallon RC tank on the same credit card charge as my car fillup...)

Seems like I've read in this thread or the DLE30 thread that JODI, WHO USED to be at ValleyView RC and posted here frequently, said that using the coleman fuel would void the warrenty. Beilieve it was said to have less octane. Have seen few post where some do use & like it, but seems the majority recommend against it.

Got it. No more Coleman fuel for me. I'm off to the gas pump to fill 'er up.

TOM made reference to a sticky for people like me new to gas engines. Couldn't find it. Could someone post a link please?

Thanks again for patiently clearing up the fuel question for me.

Did I miss something? Is Jodi no longer working for Valley View? Heck I buy all of my DLE engines from Valley View because Jodi is there. There are many other places that sell DLE for tha same price and on occasion for less.
