No, I haven't changed it yet but I plan to tonight. I figure a change of fuel once a week should be enough. I don't expect it to make any difference, but like you said there's always a continuous flow of fresh fuel coming into the carbs. Makes sense to try to replicate those conditions as much as possible...

Been away for a while. Excellent topic, I asked a similar question on another site about blending E-85 and gas to run in a turbo buggy( higher octane). Most guys said try it and let them know how it turned out. I was worried about the unfinished/ non coated aluminum( spun aluminum fuel tank). Keep the updates coming. Thanks Dave T

Welcome back...
I've been doing some more research. You gotta be careful what you read about this stuff. It seems so easy for people to start talking about "the facts" when they actually have no idea what they're talking about. (like me!)
Tomorrow will be 2 weeks for my testing. I'll have more pics to post this weekend.

i've been making homemade vegie diesel for about 9 months now and have had a supply of Methanol on hand. so i tried a little in my turbo engine and its was in the system for about 2 months now with no ill effects at all. But i will not keep out the capital SO FAR. And just my 2 cents on the environmentally friendly thing You have to take a look at the broad picture. Doing my research on bio diesel i learned that if you take into consideration the emissions dumped to plant ,harvest ,and process corn into ethanol and soy into bio diesel they average low on the crude oil side. But i process used veggie oil so that is a renewed energy that would otherwise be dumped. Mcy d's will always use vegie oil so why not renew it. But just some food for thought.

On the subject of Biodiesel, do you have a complicated setup or a basic set up?? Meaning do you just filter the oil and go or do you heat it,add to it ect ect...??? thanks Dave T

I like the biodiesel idea! My boss has been making it for the last several months. He burns it in his wife's Jetta and loves it. He's claiming about $1.25 / gallon cost. That's without a fancy biodiesel kit, just him in the basement with buckets and drums. He also has a supply of methanol, he bought a 55 gallon drum worth. I read a little something that explained using ethanol instead of methanol to make biodiesel. The process is very similar and you can make ethanol at home if you want.
I'm not sure I would try methanol in my gasoline engine due to it's corrosive properties. A full on, methanol compatible fuel system is highly recommended. That's one of the beauties of ethanol. Also, I can't remember the numbers off hand, but if e85 (ethanol) is only 75% as efficient as gas, methanol is only like 60% as efficient as gas. It's all in the BTU's.

As far as my e85 testing... I wasn't able to get any pics this weekend. Everything looks the same. I unfortunately had another birthday on saturday and with the in-laws and everyone at the house I didn't have time to mess with it. Tonight I will change the fuel for fresh and get some more recent exciting pics.

I forgot to address the point you brought up about being "truly green". You may very well be correct on this. Some people say it takes more energy to produce the e85 than it gives in return. All I can say is that it costs me (the consumer) less, and I believe it's definitely a step in the right direction. Maybe not "the answer" but sure is better than the old way of thinking.

Running straight oil is asking for problems. I've heard it will work, but not recommended. Converting it to biodiesel is somewhat complicated but there's a lot of info and instructions out there. My boss get's about 20 gallons of biodiesel out of his small- scale setup per batch. You do have to heat it, mix it, separate it, filter it, etc... I would say (from listening to him) that the separation/ filtering is the hardest part.

If I had a diesel engine I'd be making it too! There's no conversion needed for the engine to use it.

i use 5 gal. steel buckets. A very basic setup. The oil has to be heated to 120 deg. and the methoxide is mixed in. The used oil really doesn't have to be filtered very finly because after the methoxide is mixed in.The glicerides seperate from the esters and fall to the botom and so do all the other sedements. I've ran straight unwashed very crudly made(not bashing myself) biodiesel with very good success. Ive gotten as premative as it gets making it just to experement on how self relient one could be.heres some links

Hello... Any updates?? Thanks Dave T

This weekend will be a month of soaking parts in e85 and gasoline. Sorry I haven't been keeping everyone updated. I've been really busy around the house (just built a deck) and watching parts soak in jars just isn't very exciting. I can't say yet, but it looks pretty promising so far.
So here's my question... Is 1 month of soaking parts long enough? Or should I go 2? Seems like a month would be long enough to see any changes, but 2 maybe better just to be safe. I'll update this weekend...

Well it's been over a month, any change?? Thanks Dave T

Sorry for the delay...

The parts are still soaking. No change or anything as far as I can tell. They have been in there since sept 6th, so over 2 months now. I think I'll just let them sit indefinitely.

Here's a picture from about 2 weeks ago. Big jar is E85, the other is straight 87 octane gasoline


I'll continue my testing, but now I'm wondering if it's even worth it to actually try and convert my buggy to E85. I honestly can't see any harm in it for the engine, but the whole "green" thing might be questionable. It depends on where you get your info. I still like the idea of not relying on foreign oil...

Yea I'm not so worried about the whole green thing but I want to use it as an octane booster for my turbo buggy. Thanks Dave T

What kind of mix are you thinking about running?
I've been thinking about a 50-50 mix or something. I need to figure out what kind of octane that would be... Also, with gas prices well under $2 here now, I wonder about the long term availability of e85. I know it's not much trouble to put the old jets back in if e85 gets harder to find, but it's just a pain in the azz to deal with and I'm lazy.

Well 50/50 sounds good, But I have to wait until I build the engine to get the C.R. Thanks Dave T
