lcxu105 Posted August 12, 2016 Share Posted August 12, 2016 Ok. I'm about to fit my new 3025neo to my car. It only gets use maybe once a month and can sit upto six weeks at time and not move. So e85 is out of the question. So the big question is. What is the next best fuel to run.

GTSBoy Posted August 12, 2016 Share Posted August 12, 2016 E85 is not out of the question. I would suggest that you can take the tinfoil hat off. There are many people on these forums and others reporting that E85 sits just fine in a fuel tank without absorbing the Pacific Ocean. And if you left the tinfoil hat on there are ways and means that you could get around any such problem. Such as, put it away with a nearly empty tank, and put fresh fuel into it from a jerry can just before you use it. Or any variation on the theme. Let's face it....old petrol is worse than new petrol. If you leave old petrol in a tank for 6 weeks it will change over that time. If you ever find yourself leaving a car for a long period of time then the best thing is to leave it with as little fuel in it as possible and put new fuel in it immediately - well at least before giving it any curry.

Lithium Posted August 12, 2016 Share Posted August 12, 2016 I must be missing something here, 20 minutes ago, lcxu105 said: It only gets use maybe once a month and can sit upto six weeks at time and not move. So e85 is out of the question. I must be missing something here, there is a general statement then E85 gets ruled out.... how are these two things related? Pretty much everyone I know who run E85 use them about that much and leave them for that kind of time period regularly as we don't get E85 at the pump, so it's usually a race car thing and the cars tend to sit with it. The only issue so far with my mates ones have been one which had non-E85 compatible foam in the fuel tank which got dissolved and caused issues in the fuel system... lots of crap through everything, but easily avoided by making sure everything is E85 compatible. Most race type fuels have down sides and things to be aware of, if you're going to be paranoid then use 98.

Dose Pipe Sutututu Posted August 15, 2016 Share Posted August 15, 2016 Flex? I run E85 when I feel like it, car barely gets driven.. if I know it's not being used for long periods I just drop in like half a tank of 98RON and blend that shit. 2 Link to comment https://www.sau.com.au/forums/topic/466255-witch-is-best-fuel-to-run/#findComment-7766671 Share on other sites More sharing options...
Ad's Posted August 21, 2016 Share Posted August 21, 2016 My car sat with half a tank of E85 whilst I had the motor and box out over four months. Starts and runs fine every time and the same fuel will still be in it when it leaves the garage in October, obviously I'll fill her up with fresh E but Iv never had a problem.Another point- That fuel has been sitting in my tank since last December.Plenty of people let it sit and never have issues.

iruvyouskyrine Posted August 21, 2016 Share Posted August 21, 2016 Have used lots of old E85 that people have given away for sitting over 2-3 months. Oldest fuel I have used is easily over 1yr old and car ran fine, AFR was fine. This was giving the car a very hard time at Queensland raceway as well in 40deg heat Link to comment https://www.sau.com.au/forums/topic/466255-witch-is-best-fuel-to-run/#findComment-7768495 Share on other sites More sharing options...

lcxu105 Posted August 22, 2016 Author Share Posted August 22, 2016 Not all fuel systems are fully sealed. Mine is a lc torana. They never sealed properly from factory.

GTSBoy Posted August 22, 2016 Share Posted August 22, 2016 Doesn't matter. Exactly what is going to happen anyway? I won't type it all out again, but perhaps search for a couple of posts on here where I tiraded over the stupidity of thinking that gallons of water can get into your fuel tank through whatever air movement there is.

Dose Pipe Sutututu Posted August 22, 2016 Share Posted August 22, 2016 and a bit of water in your fuel isn't going to make your motor go bang... heck, imagine it like a bit of water injection Link to comment https://www.sau.com.au/forums/topic/466255-witch-is-best-fuel-to-run/#findComment-7768980 Share on other sites More sharing options...
mikel Posted August 25, 2016 Share Posted August 25, 2016 yes E85 is hygroscopic, ie will absorb moisture from the air, but at the same time, 98RON fuel has additives which are quite volatile and will "gas off" over time which will reduce the octane rating of 98 if left to sit. A bit of absorbed water in E85 is less likely to affect it's octane rating, as it's the ethanol content that provides the high octane. Normal 98 fuel left sitting could be closer to 95 octane by the time it's sucked into the engine - IMO a bigger risk on an engine highly tuned for fresh 98. IMO the "sitting" time is not a good criteria for deciding E85 vs 98. It's more about your horsepower requirements, availability of E85, ability to fill up on a long drive, carrying jerry cans of fuel etc cheers Mike 1 Link to comment https://www.sau.com.au/forums/topic/466255-witch-is-best-fuel-to-run/#findComment-7769927 Share on other sites More sharing options...

Piggaz Posted August 26, 2016 Share Posted August 26, 2016 Opened up my filters two weeks ago after sitting around from November with E85 in the tank. These fuel filters were cleaned in July/August last year. This is what came out. Was pretty yuck. Whole fuel system went in the bin!
