its all i use now. i use boost 98 from united petrol stations. ethanol burns better/more efficiently than petrol, also provides higher octane, and its cheaper!

only a few subaru models arent supposed to use it. b4 is one of them.

yeh, the 98 stuff you use alexx was betta then the normal 95 octane, but i still didnt think it even matched the 'normal' 98 stuff. im just being a little baby because of my new jap spec ecu to be :hunter:  and being a student in business managment, i can forsee petrol being added with ethanol to cut the costs to the business (which ofcourse dosent mean itl be any cheaper)

Organic Ethanol can be extracted from sugar cain. You can also extract organic deisel (From someother plant). Once extracted they are both refined and cleaned.

Both Octane and Ethanol have the Carbon chain.

Here is a quick basic Chem lesson for you guys:

Meth... 1 carbon atom
Eth...   2 carbon atoms
But...   3 Carbon atoms
Prop... 4 Carbon atoms
Pent... 5 carbon atoms
Hex...  6 carbon atoms
Hep...  7 carbon atoms
Oct...   8 carbon atoms
ect.

These Carbon atoms have a covalent bond between each other C-C.

Now that name on the end eg. "ol" "ane" "ene" ect. is determined by the bondage in the atoms say single or double bonds also if the molecule has a alcohol group attached to it "OH", but said "ol"

To make it a little more clear here are some pics of a Octane molecule and an Ethanol molecule:

Octane:


Ethanol:

does anyone know how many of that stuff you need to make the alcohol they use in top fuel?

standard engines can take up to 23% ethanol mix without seriously messing up the engine.
there are advantages to it such as less carbon deposits everywhere (burns cleaner) but its also going to be a lot more expensive if everyone starts using it, simply cause it takes a lot of energy and raw materials to make (fractional distillation, essentially a still, the way people make rum).
brazil tried it for a while but found it wasnt economically viable cause it took up too much land to grow all the sugar cane needed to provide enough raw materials to make enough ethanol to power a nations cars.

with the Subaru's the ones which arnt ment to run on ethanol are the B4's and the 99/00 STi's as they were imported from japan.
i emailed subaru a while ago and they said something about not covering cars under warrenty if they use the ethanol as Subaru do not recomend it...

so if they run on 98-100 octane over there, how come they cant run with the same level octane, just with some ethanol in it.

gold star for you my friend :clapping:

Seems like a good test but you'll never know the long run cost of what is happening to your car. Will it be worthwhile if your engine loses 20,000ks on the end of it's usual lifespan?

Ok cool thanks alexxx I wasnt sure on the name. I'll try test both I just hope I can get it all done befor I go on Holidays.
