Earlier today, I noticed this E20 gas that's 91 octane and about 30-40 cents cheaper than anywhere else's premium. I've also seen a LOT of gas stations have also lately switched to 91 octane. I've been using 93 exclusively for the past what, 3 years now? Anyway, I was wondering, will I see massive spikes in KR from using 91 octane instead of 93? Is this E20 stuff safe to use? My mods are as follows: Customized DHP 1.5, 180*, PLog, 2.5" catted DP, 104s, and a 3.5". This would help me out a ton if I can use it, otherwise I'm limited to maybe three of four local gas stations further from my house.

91 would be safe

E20 you will notice a drop in milage and it may run diffrent. are cars are way to old to really know what will happen with E20 as they are only garentied for 2009 model year or newer.

i know for a fact the LeBaron hates E10 fuel it gets a weird little hesitant fart when idleing

I ran e85 once. Car ran okay but I took a 20% hit in mileage. I presume e20 would be similar with less of a mileage drop.

Honestly I would just get the straight 91. Or is everything mixed with ethanol by you?

Everything is mixed. So in reality, I have basically two choices. Pay $4.29 for premium 91, or $3.89 for E20 91. lol I think I know which route I'll take. Thanks guys.

straight premium will save you more int he long run becuase fo the milage hit

true fact lol

You'll be fine running it, but as Tom and Austin said, mileage will drop a little. My average MPG goes from 29-30 with straight 93 to 26-27 with 10% ethanol mix and the idle is pretty crappy and feels like it misfires like a mofo.

Truth

Your car isn't setup for E20 so you should run premium since it's E10. I only run premium in my car since I don't want the higher ethanol content.

I like ethanol free gas stations.

We all do, but it's hard to find gas without ethanol.

Not where I'm at. LOL. Most of the stations have an ethanol free option, even if it is only the premium fuel.

Damn! must be nice! ha
yeah as we all know it takes more flow from your injector's to properly run any good amount of Ethanol in your gas so if a guy just goes and fills up with a higher content of Ethanol(without a tune or any adjustment,too bad our pcm's don't have a table for this) the car's gonna be running lean. Nice thing is it still probly won't knock via the cooling powers of the extra E but it will run different. I even wonder if E10 can cause fuel trims to be more offset than if you were to run ethanol free gas.

The ten percent blend that is common messes with the old Volvo pretty good. I drop, on average from 2-5mpg, and probably drop 5-20HP. Sometimes, I have to use it, but I hate it. The car runs terrible on it. Ethanol is bullshit in the grand scheme of things. Cars are different enough that they should NEVER have even considered it.

How do you figure you use HP when ethanol has an equivelant rating of 100+ octane to gas?

And i think ethanol is good stuff people just shouldn't mix it with normal gas without being able to make their car's adaptable to the new fuel type.

Energy density is why. Ethanol has a ton less of it compared to gasoline (Specific Energy :46.4MJ/kg for Gasoline, 30MJ/kg for Ethanol Specific Density: 34.2 MJ/L gas, 24 MJ/L ethanol). Octane is ONLY a measure of detonation resistance, not how much energy a fuel contains. The high octane rating of ethanol is why people like Glanzer can run stupid small pulleys on GP's, and in cases like that you can make huge amounts of power, but a normal car that isn't pushing crazy amounts of boost, has small injectors, and isn't tuned for it will be hurt by running any sort of ethanol, mixed, or straight.

I was thinking about the whole mixing ethanol thing today, and it honestly should be something that the government steps in and cracks down on. Think about it this way. Ethanol will net you worse mileage, so gas companies put it in their regular gas to get you to come back sooner, yet will still charge you up the ass for it. No wonder why they are having record profits even though crude prices are at an all time high. And Ethanol is a bunch of crap anyways because of how much energy it costs to make and how much if effects food prices.

Wish that was the case around here. I just found out the other day that the local coop stopped selling non-ethanol fuel. Pissed me off cause it's not good for my 73 at all. And the feds are talking about mandating 15% now. UGH!

Oh fantastic. Just more proof that half the d-bags in the government are getting paid off by oil companies and lobbyists.

The feds are the ones that mandated the ethanol mix. And they're talking about mandating 15%. They're subsidizing the ethanol industry and are in the process of forcing EVERYONE to switch to some type of ethanol blend. My local Coop fell victim to this recently. They held out as long as they could but I have a feeling they got a visit from the feds "reminding" them of the 10% mandate.

It's not the oil companies, it's the corn industry (we're talking about the corporation "farmers", not the little guys who have no voice). As far as the oil company is concerned, the % of ethanol that goes into gasoline is money that they don't see. instead of getting 100% of each gallon they only get 90%. And if the feds get their way the oil companies will only get 85% of the revenue. You really think they're on board with that? I would guess no. Feds don't care, they get their tax revenue (which for the feds is about 6 times the profit the oil companies make per gallon) and also it helps make the enviro-wackos happy (even though scientists are not in consensus on ethanol being "cleaner" than gasoline). I'd put money saying the oil companies would LOVE it if the feds stopped subsidizing ethanol.

the mandate is not an issue for newer cars but any car older then 2005 can not run E10 correctly they where never programed to run it from the factory (why Joe's volvo runs so poor) and E20 is really only for 2009+ vehicles as well.

ethynal is only good for crazy high compretion full effort N/A cars or high boost cars.

my merc wile can actualy handle it pretty good still has a noticible change in idle when i put in E10 vs. straight. problem is there is not straight gas where i live and michigan is not even required to advertise it so you do not even know before you fill up

I had the same problem in Kentucky where they weren't required to say whether it had ethanol or not. In TN they're required to label but it's getting harder and harder to find it w/o ethanol.

kcuf. Well, there goes that idea. I know my dad's 2003 Sebring (glad it's gone, POS) could handle even E85, but I don't know if it could handle E20. I think his current car (2010 BMW 328i) can fairly easily, but we will see.

I saw a flex fuel tag on a 1998 Taurus... I didn't know the E85 thing went back that far. I thought it was since like 2001?

98 they had no E85 in 98. more then likely the guy grabbed a trunk lid froma 2001-2003 tauras

but your dads car being a 2010 it could use E20 no problem.
