OK so I was wondering which gasoline you guys are using in your favorite 2 Stroke Engines and why?

I'll start:

I own a DA-70 Twin a couple DLE 20's and a DLE 55 and have been using VP 4 Stroke Gasoline (94 octane, no alcohol) mixed with Redline oil at 40:1. I buy it by the case and its not cheap, but I like it.

Why? Well because the DA recommends 91 octane or better. I think its better to use non alcohol gas and you cant get that at the pump. Also, the high octane pump gas like 91 to 93 octane also contain alcohol and since the last few years, the price difference in 87, 89 and 91 (better known as Regular Grade, Midgrade and Premium Grade) has not been 10 cents as it used to be. I have seen Regular Grade gas go for say $2.00 a gallon and Premium Grade go for almost a dollar more. To me, that means that the average consumer will not pay the extra for premium, so it will sit in the ground getting old and bad especially with the alcohol in it. So pay a lot of money for crapy old gas. Nope. So I refuse to buy that crap gas and put it into my RC Plane engines.

Also, the VP gas does not smell like gas. So if I spill some in my vehicle, it doesn't leave that horrible gasoline smell.

How about the rest of you????

your logic is a bit flawed. the so called average consumer pays the difference for premium if whatever he or she is driving is tuned for 91 or higher octane, and that's an awful lot of vehicles. It is not available as an "upgrade" for people who are using 87. You can run 87 in DAs without any problems if you are concerned that the local 91 is stale.

You need to know what the compression ratio for your engine is. If it is greater than 11:1, you need 91 octane. If it is lower, you can run 87 all day. The ethanol blend is a separate issue. If non-ethanol is available in your area, it's a no brainer to use it.

Sure can tell the winter is here.

I run 93 octane Chevron or Shell.---Smitty

I use whatever gas, literally, it doesn't matter......Its what I have used for maybe ten years and
redline 64-1 (2 oz per gallon). I never worry about where I buy gas and my DA motors don't
either. I have owned multiples of every engine they sell and will never waste my money on
VP gas. Its a big waste of money. My engines perform well and last for years w/o maintenance.

I use Sunoco GT Race Fuel.. 100 octane an mixed with AMSOIL DOMINATOR Synthetic 2-Stroke Racing Oil @ 45:1.
Not sure of any performance advantage, but if you spill some or get it on your hands or clothes the smell is gone almost instantly. i've been running this fuel for years..Never had any issues at all..
I do remove the unburned fuel from the tank, but i have never ran the carb. dry. Racing fuel also stores very good. Hardly ever goes bad

91 octane non oxygenated and Stihl Ultra HP 40:1

I'm running ethanol free 89 octane Mixed 40:1 with redline In my DA 100 and 170

What ever I can get.

89 octane ethanol free

If I could find a premium non-ethanol, I'd run it because I do believe alcohol hardens the (Tygon) fuel lines. After years of chasing 100LL Avgas and 87 octane non-ethanol, I've decided to plumb my lines inside the tank with Viton and simply run the gas Desert Aircraft recommends. But having said that, we all gotta do what we gotta do.... Good luck with whatever you choose.

Thank you for your reply FGN. While I appreciate your reply I don't think your are correct about you opinion regarding the tuned to 91 octane vehicles. I only say this since I know for a fact that my Jeep Grsnd Cherokee overland requires 91 or better for best performance. If however the owner chooses not to use higher octane gas then they don't have to. The vrhiclrs computer utilized engine knock sensors, O2 sensors and a bunch of other technology to compensate for best engine performance. I have observed this in my Jeep and feel the difference in the engines behavior. Further, I think you missed the point of my question. You added absolutely nothing to the conversation. That's your right though. Thanks again for your reply.

I will get fuel from a local high volume gas station. Usually 91 octane because i run tuned pipes. This myth about the 10% ethanol causing issues in our engines is just that, a myth. You let your engine sit for a while the gasoline and ethanol will evaporate out of the carb. I have ran thousands of gallons of E10 gasoline through my 2 stroke engines and even after sitting for a few years my engines still fire up as normal and run fine. As an example, this year i started my jetski after sitting since 2014 with a mostly full tank of fuel. I wanted to get rid of that gas and decided to not fill up with fresh fuel. My engine had no problems running 64 mph at 7000 rpm for most of the day. Not bad for fuel that is over a year old. My other ski sat for 2 years untill this year. Same experience. I think more people have issues with tuning than actual fuel issues. They just blame it on the gas.
