Re: Ethanol in gasoline...how does it affect?
 

10% wont' do ----; it just UPS octane compared to regular gas. so be happy

and every car built since 88 sold in the US is supposed to handle AT LEAST 10% ethenol blends. most can be converted to E85 without having to swap all the fuel system components.

IF you guys would get your heads out of your asses and stop believing what some guy said on some forum and do your own research you would see that ethenol + gasoline = GOOD THING!

/edit: and if you're "noticing" a drop in millage going to 10% its your imagination. if you put in 10% and KNOW you are taking a mpg hit then bump the timing about 4 degrees and get it back.

My uncle (who commutes 200 miles per day) found a decrease of 2mpg (in a saturn of some kind) when going to 89 w/ ethanol from 87 w/o. You could easily install an AFC and lean it out a touch to recover that, since ethanol burns cooler it would probably be fine.

The 10% ethanol is just a way to prop up the family farm.

It takes more energy to make ethanol from corn than it produces in the end. :P

Ethanol is not an oxygenate. That one lone, lonely -OH stuck off the the side does ---- all for power production.

For a given tune, substituting 10% ethanol blends (e10??) will lose power, and run you a tad lean. Totally awesome!

So you can make more power with the same amount of air as a system running gasoline, though you need more fuel so the MPG drops. It burns cooler than gasoline, so you won't need as big of a radiator on a system that only runs E85. It also is cleaner than gasoline, [/quote]

You cannot make more power from ethanol "because it is an oxygenate". You make more power for a given airmass from ethanol because it produces a higher water:contaminant ratio aka burns cleaner. Crack a book on steam turbines sometime; Heywood and Taylor have mislead a generation of IC engineers with their contradictorily footnoted and referrenced primers.

With current gas prices, it costs as much per gallon as gasoline currently does... but you need twice as much, so it's a ---- in the ass.

All I know is that I'm gonna buy me some land and grow me some corn.Pretty soon corn farmers will be like roleing in crazy money.Its time to become a farmer :8....... :P

Quiet, people will figure out my little MPG secret and why I use cheap gas!!!!!!

53 mpg rocks!

Re: Ethanol in gasoline...how does it affect?
 

I wish I got 53 mpg, my ~26 mpg sucks ass

Re: Ethanol in gasoline...how does it affect?
 

Retune for 16.x:1 AFRs, disable tip-in enrichment, and run lodged in open loop. 2700 ft elevation where everything's a hill, all stop and start city driving, STILL carting around a couple transmissions and a toolbox and a backseat full of debris, running the AC half the time = 32 mpg.

I'm really tempted to retune for the 17.x:1 AFRs, and clean my car. I know she'll tap 40 mpg on flatland cryuise w/ AC running as things sit now... 45 would be nicer.

Re: Ethanol in gasoline...how does it affect?
 

wrong, people want a cleaner fuel and burning ethanol is cleaner and cheaper. there is a few countries that only burn ethanol and no gas mixed in, they are dependent only on corn not crude oil.

right now it does cost more to produce ethanol only because its a new trend. after a few years it will be far cheaper to produce ethanonl and burn it than to produce gas
