Buildup For Ethanol - Ideas And Disucssion On How To

[Sam_Q]

that would be really interesting to see that. What compression ratio are you going to go for?

 

On my side I get my car back tomorrow and then I will see what its like with and without the E10 seeing it would now be tuned for it. Also I should pull the head off my old 20v soon and check it out. I did the 40,000km or so on almost completely E10 and not a whole lot else, would be interesting to see how much ash is in there and anything else.

Sounds good Toyocharged.

 

My main concerns aren't with the tune etc, I'm more worried about the compatibility issues with my soon to be 40 year old car. I'm probably getting a bit anal though....

 

MY fuel pressure reg (holley) isn't compatible, but I reckon I'll just throw it in anyway.

 

Anyone got a manual for a Carter fuel pump, I can't find info on the web at all to determine if they'll run with Ethanol.

The pressure regulator gaskets will probably be the things that don't like ethanol. The rubber O rings and things will more then likely turn to mush.

 

On a side note, I didnt think E85 was a readily available product in Aus yet (as in sold to the general public, I know I can buy it through the guys I get my racing fuel, but not at servos and stuff?)

 

I refuse to run the E10 in any of my road cars no matter what people say about it, The cars arent designed to use the fuel, so I'm not going to go throwing it in there until its been tested for atleast ten years.

 

for a couple cents a litre difference I like the piece of mind that I'm not going to have long term problems from using an alternative fuel.

If you want to see if it will fail just leave it soak in pure ethanol for say 6 month. Changing it regularly, no?

[philbey]

all the brands of pump and regulator usually state - not suitable for Alchohol. They don't discern if thats methanol or Ethanol, so I might be alright with Ethanol.

 

Suck it and see.

 

You'll find that a number of modern car manufacturers allow a certain amount of Ethanol in the fuel with their warranties, usually up to 10 or 15 percent. Thats if you have a new car though.

ah shit, I had my car tuned for the fuel that was in the tank which I though was 98 octane E10 fuel, now I find out that a little while ago United fuels have changed it so only 95 octane fuel has the ethanol blend.. crap!! so its just normal 98 octane fuel for me

The trouble with smaller fuel company's is that sometimes in an effort to make a larger profit they will add cheaper solvents to there tanks.

this happened to me a few years back i had it tested in a lab at work and it showed up traces of Toluene and Methyl Ethyl Ketone(MEK) both ingredients in paint thinners worth 20 cents per litre.

 

The hoses ,rubbers,pumps have no chance Teflon is the only seal i know of that will stand up to them.

well I would actually like for there to be more tolluene in my fuel but the government took care of that a while back by putting a heavy tax on it to not make it have any discount over normal fuel. I don't know if United would chuck something like MEK in the fuel as they arnt a small company. Well I atleast know their bowsers measure their fuel fairly correctly unlike Caltex
