E85

[mcafferty]

anyone have any info on this? has anyone switched their LS to E85?

 

[mcafferty]

Retune, injectors, lines, etc???

Not real sure, but I wouldn't try it.

I'm relatively certain that E85 is not OK for the LS. I don't know what all you'd have to replace to make it E85-compatible, or if you even can (f'rinstance, can the PCM handle it?).

I've swapped to e85 in a couple of other cars.
The most I had to do with them was change out and rubber o-rings or fuel hoses to neoprene or silicone and get a new chip tune.
e85 has much better octane numbers, but it also has less energy density then regular gas, so to make the same power with a gas tune will take a noticeable chunk out of your mileage.
That combined with the utter lack of a reliable supply in this area has stopped me from bothering to look at the ls for conversion.

Keep the info coming. It is avalible where i am at. If a flip chip, tune and o rings i all i need then that would be cool. I have my tuner looking into it. Thanks for the info

why would you want to?

 

[mcafferty]

$$$

 

[pwr2killayak]

for a savings of maybe .10 a gallon? 10 gallons= $1.00? not even worth the trouble... have fun.

just wait until one day the US gets cut off from oil supplies, who will be laughing then? corn burner baby!! :dancefool

If and when that happens how many of us will be still driving our LS?

 

[mcafferty]

the price of 91 is 3.15 the price of E85 is 2.20

Yeah E85 is WAY less in both cost and effeciency. So i think cost per mile is about the same. I don't know if that low effecient fuel would work well in a high compression engine like ours. It's a GREEN thing - making fuel from a renewable resource - rather than a cost savings thing.

Do you know how much oil it takes to produce E85?

Far more than it would be worth to invest in corn right now.

I'm assuming you're talking about oil consumed by machinery at an ethanol plant? If that is the case, the argument would only prove worthy if we knew the consumption of BOTH an ethanol plant, and an oil refinery. Also, the positive impact on the economy by purchasing domestic product to produce fuel as opposed to the negative impact by importing foreign oil. Don't you think the UAE has enough money?

e85 has a much higher octane

here this is quoted from a e85 page.

Ethanol has less energy content than gasoline. However, E85 also has a much higher octane (ranging from 100 to 105) than gasoline. FFVs are not optimized to E85, so they experience a 5% to 15% drop in fuel economy. This will vary based on temperature and driving conditions. For comparison purposes, aggressive driving habits can result in a 20% loss and low tire pressure can reduce mileage by 6%.

So while it has less energy than conventional gasoline it has a higher octane rating, which is what the high compression of our LS motors need.

 

[pektel]

Wow, I never knew that... thanks for the info!

 

[mcafferty]

I dont want to start anything just was looking into it. to see if it is a viable option.
