Flex Fuel, E85

Are the LS3 or L99 flex fuel enabled? TIA!

I'm gonna say....no they aren't meant to run that. And it's recommended you run premium fuel in them.

Get it while you can Obahma is planing to go for 35MPG by 2015 and then you can get a E85 4 cyl. and wish you had the real thing.

The following is not political opinion. This is political fact from a political scientist. Remember that Congress has far more power than any President. Be sure to convey what you want passed or rejected to your elected officials. Failure to do so will result in not getting your way. Democracy demands more of us than just voting. Contact your elected officials to make a difference.

Actually...you don't get better mileage with E85, its just a greener fuel.

soon technology will allow us to find a way to run less powerful engines with gaining more power with more fuel efficient products... dont b so scared of change.. 1 day the things we need will in fact run out.

think first.... then post.....or do research...........wikipedia and howstuffworks.........

E85 has an octane rating of 100–105 compared to regular gasoline's typical rating of 85–93

but manufacturers do not tune E85 ethanol-capable engines for higher performance than their gas-only counterparts

Automakers spend an estimated $150 to make a vehicle E85-ethanol capable.

They do this by the elimination of bare magnesium, aluminum, and rubber parts in the fuel system. Also, fuel pumps must be capable of operating with electrically conductive ethanol instead of non-conducting dielectric gasoline fuel. Fuel injection control systems have a wider range of pulse widths to inject approximately 40% more fuel. Stainless steel fuel lines, sometimes lined with plastic, and stainless steel fuel tanks in place of terne fuel tanks are used. In some cases, E85 vehicles use acid-neutralizing motor oil. For vehicles with fuel-tank mounted fuel pumps, additional differences to prevent arcing, as well as flame arrestors positioned in the tank's fill pipe, are also sometimes used.[citations needed]

..........


How I read it ............. E85 + tune = more horsepower

.....wikipedia and howstuffworks
but E85 is less efficient than gasoline, so you end up using more of it

I think the $150 is on Teflon fuel lines and gaskets as ethanol eats them up.
For one, you would need a higher compression ratio to take advantage of the higher octane rating.

Two, there is less energy available per molecule of ethanol than gasoline, so you have to use more ethanol to make the same power as gasoline, meaning your gas mileage goes down. That goes back to the earlier statement saying that it's not more efficient, it's just a greener fuel.

True. There's something else to consider...when ranking fuels from most energy-dense to least...Ethanol ranks next under gasoline. So, yeah -- it's less efficient. BUT...what does that matter if it costs less? General trends have ethanol getting cheaper as they produce more (NOT from corn), and gasoline getting more expensive as oil wells dry up. So dollar for dollar...you're not paying much more than a couple bucks a tank.

If it cuts the car out of the "environmental equation"...hell, I'm up for it. It saves our performance cars from the scrutiny of 'greener' eyes. Plus...when they start making it from algae (5-10 years to full-scale production)....we'll have an almost unlimited supply of this crap.

I think its good to look at alternative to gas based engines, look at the Tesla, 0-60 in under 4 seconds, if it was a conventional gas engine everyone would be all over it. Being electric and with only 1 gear many gear heads are biased against it.

+1 for algae ethanol!! They also have a strain that produces diesel with NO sulfur! I'm guessing a solid 10 years before either are functioning on a big enough scale to put a dent in OPEC, but I can't WAIT til they do. Hooray for energy independence!

You mean that's if some big oil company doesn't buy them out first.

Ethanol will start to make sense eventually but even at the highest oil prices we've seen ethanol has been more expensive per mile, much more when you factor in the tax money used to subsidize ethanol production at this point. I look forward to practical ethanol or other biofuels, cellulosic and algae production seems to have great potential if we can get the production costs down to a manageable level.

Oil companies don't go around buying stuff up just to sit on it, they buy it to gain an advantage on their competitors. Many of the larger companies have already been investing in alternatives to diversify themselves and if they find a way to undercut the competition with a new ethanol production method or anything else they'll do it in a heartbeat. Sure not everyone in the oilfield loves biofuels but the big oil/energy companies are effectively run by bean counters like everywhere else.

Technically yes, but apparently with presidential powers the president can do anything he wants and claim presidential powers.

+1

E85 prices seems to rise and fall according to the regluar gas prices. If they EVER get ethanol to where it's economically feasable to run it, I will. The benefits are HUGE, especially for the FI folks. The problem for us daily drivers is that it cost more to run it on a day to day basis since you get less MPG out of it. They would have to sell it at roughly half the price of regular gas to make it economically worth while.

Perhaps you missed the news piece where GM invested $890 million in it's next gen V8's which will ALL be E85 capable and be direct injected. So yeah. And keep the politics out of the forum leave that for the political blogs.
