Are you sure about "butenol", Larry? Do you mean butanol? Butanol is butyl alcohol, i.e. a pure alcohol, C4H9OH. It has some of the same solvent characteristics as ethanol, C2H5OH. Both are very good fuels, particularly from an anti-polution point of view. But both could be hard on some gasket materials. And they have burning velocities which are rather different from gasoline, which is mainly a mixture of octanes, nonanes and decanes (C8H18, C9H20 and C10H22). This could mean that an engine's timing would have to be set up rather differently.

No John, I'm not a competent chemist and my spelling gets clobbered by my typing, but a proper formulated butanol doesn't absorb water, is a better solution than ethanol not competing with food products and doesn't require huge amounts of water to produce. I think they are still considering these aspects or hope they are. In areas of ethanol production, the dropping water tables affect large area access for everyone here with well water.

From: "rampil" Larry, Let's not get carried away. All short chain alcohols are soluble and mixable with water, Butanol only somewhat less so than ethanol. It has somewhat more energy density than ethanol, but still less than gasoline. Interesting but not magic. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=197913#197913 ________________________________ Message 5 _____________________________________ Time: 11:56:46 AM PST US From: LarryMcFarland Subject: Re: RotaxEngines-List: Re: Butenol??? I'm not enthused one bit about any of the alternative fuels as I am about 87-octane with or without 10% ethanol. It's more economic and my Subaru likes it too. Don't think it's going away any time soon unless Obama and the socialist bent environmental people get their way. Then all bets are off.

If you are going to use 100LL then use a semi synthetic. Full synthetic will not suspen the lead and it falls out in the gear box and crankcase. If you only use 100LL once in a blue moon then a full synthetic is still good. There are of course different synthetics, but two I recommend and have used and is used by thousands of Rotax people are Mobile One 10-40W or 20-50 and AmsOil 10-40W or 20-50W. You need to use the motorcycle ones of these oils. The motorcycle oils have special additives for engines that share oil with the gear box. Regular auto oil does not have this. Yes auto oil will work and some say look my Rotax still runs, but you will pay later for lack of the additives that are needed for the gear box. This is taught in all Rotax classes. If you are going to use 100LL more often or all the time then two good semi synthetic oils are Aero Shell Sport 4 plus which was made with the Rotax in mind and Golden Spectro 4. Both of these have excellent properties for the Rotax engine and all of its needs. These also are motorcycle oils with the special additives. Some use CPS's RV-9 oil for the Rotax. If you use 91 octane change oil every 50 hrs. and if you use 100LL every 25 hrs. This is also taught in the Rotax classes. Change your plugs at 75 hrs. and 40-50 hours with 100LL. Using 100LL more or less cuts your maint. time tables in half. You have an expensive and great engine don't skimp like some and try to drain every last penny out of your maint. I am a Rotax Service Center and I get to see all those guys more often. Because we change oils as often as we do any good motorcycle oil will work (Honda motorcycle oil), but you are trying to get not only to your 1500 hr. TBO, but beyond. Yes you can go beyond if you are following the "ON Condition" inspection protocols. Mainly it is nothing more than good paperwork trail and an oil analysis at each oil change. Have fun with your Kit Fox. -------- Roger Lee Tucson, Az.

The document is produced by AmsOil, but has great info and lots of oils. I can't find the service grades of any of the oils tested in the report, specifically the API service grades. Only the brands and viscosities are listed (and batch no's etc), but not the service grades, which is specifically what I'd be interested in. Is this available in the report or elsewhere?
