15% Ethanol??

I'm convinced that the 10% in the gas now contributes to horrible mileage but now their talking about 15%! My newer lawn mower says on the tank no more than 10% ethanol or serious engine damage could occur. So how are our Jeeps gonna run on this junk?

its not gonna happen for a while so don't worry. that is if it even happens. there was a good update on it in last months fourwheelermagazine about it all. to alleviate the e10 burden, grab a nice big bottle of STABIL, ethanol treatment stuff, its the dark purple/blue stuff, not the red stuff made for stabilizing fuel for long periods of time.

What or How does STABIL alleviate the e10 burden?

hmmmm those links should work fine. newer vehicles will be able to use the e15, but gas stations are still going to have to sell e10 for older vehicles like our jeeps...

Thanks for the links. It seems that STABIL only protects the fuel and doesn't really reduce the ethanol content. Plus it's expensive. I hope 10% is the max for a long time, I can't afford to replace an engine in anything I own!

Your smart for using it living by the water. Ethanol is a magnet for collecting condensation. I know boat owners MUST use it or their gonna have a not so fun day on the lake!

between that and using heet i try to keep things in the best shape possible. :/ ya the e10 isn't removed... but the stabil does help protect the engine. which is the most important thing. i've found in my subaru that i've gained 2-mph from using it. i cant comment on the jeep bc is in the garage and i dont drive it much since the subaru is just downright dirty in the snow/handling with the general altimax artics! i go through any storm no sweats. but back on subject, i just started using the stabil around thanksgiving, so i cant comment for the jeeps mpg, hopefully i can sometime soon!! ya the stuff is a little expesive... i paid $22 i think for the big bottle at wally world. but, i'm just coming close to halfway through it since turkey day... so not too bad really. and i travel a little under 200 miles a week, sometimes more.

Sounds good, I may try a bottle and see. Heck it can't hurt anything! Oh and don't worry about the Subaru reference, my Nissan Frontier is 10x better in the snow but I don't like being seen in it so I take my chances in the Jeep!

I may buy a test kit and check it here in VA. So far my Jeeps and truck run ok on what they claim is 10% but I had a Cobalt that ran terrible once the station I use switched. BTW, the Cobalt still got 30mpg and I traded it anyway for my 13mpg LJ! No regrets!

I would not worry about E-15. It will not harm your vehicle.

And not just because of the moisture issue. All boats with fiberglass fuel tanks will be required to retrofit to stainless tanks because the ethanol will eat the fiberglass.

any brand of gas station better then others?
also, any octane rating better then others?

People tell me Mobile has lowest levels of ethanol but I don't believe them. Regulations are regulations if you ask me.

Yes it will. I have 20 cars and 16 of them are more than 36 years old. Rubber components have to be replaced regularly and carbs have to be rebuilt frequently because ethanol eats rubber. A rubber diaphragm in the accelerator pump on the Carter carburetor on my '55 Bel Air keeps failing due to ethanol. New car parts are apparently OK with ethanol, but not the older stuff.

20! Jay Leno is it you? LOL! Just kidd'n, this e10 is a real classic car hobby thorn in the side . I can't imagine my older TJs running worth a poo with more ethanol! There is a compliant site that I will look up and post. Stay tuned.

Well ok for you guys with your old old vehicles you're in trouble but for vehicles built within the last 15 years or so you will be alright. Learning all about this in my alternative fuels and emissions class. Someone ran there 99 Tahoe on E-30 and it ended up being better than E-10. Granted when they get to that point you're going to need to replace your fuel filter a couple of times because it's going to definitely clean the fuel system. Most of your vehicles built within the last 15 years are more than capable of handling E-15. The fuel systems are made with the rubber and steel that with stands the higher ethanol content.

I know what all to well what village idiot is saying.
My opinion, there is no plus side to this ethanol. except for the farmers. I build engines for a living and it doesnt have an older engine to see the effects of ethanol, just 10x worse on stuff from back in the day

The advantage of higher ethanol content is less need for foreign oil, more jobs in the U.S. and lower emissions.

We have enough oil here if they would just go get it.....and the auto makers need to get with the program and increase the efficiency of the engines....especially the diesels for crying out loud.

Compare an engine in any late model 2011 vehicle to a vehicle from 10 or EVEN 5 years ago. Efficiency has increased, emissions are down, fuel economy is up. Diesels are now being worked on for better efficiency and even today's diesels are more efficient than diesels from 5-10 years ago. Technology takes research, time and money.

hahahaha that is so wrong. Show me a diesel made today that gets 18 mpg and I will buy you a beer. The diesels from say 1980-1997 get twice the mileage of the ones today. I can tell you how to increase the diesel effciency...take all the emissions crap off it. I will never buy another new vehicle, especially a computer controlled, epa, pos diesel. No reason to pay 60K for a new truck that gets 10 mpg out of the box when I have a 68 model that's gonna get 25+

Thats exactly right...alot more to get it done. Being an alcohol it cannot deliver the same BTU's as gasoline. Its fine on the newer stuff, but it seriously jacks up the old cars....and I hate to break to everyone but the old cars are gonna still be here when these new chinese recycled american iron coated with plastic are all crushed.

Look at any Mercedes, VW, BMW, Audi with a diesel engine in it. They all get around 30-36 mpg. The diesel Grand Cherokee gets around 22 mpg. Both Chevy and Ford are boasting 15-20% increases in efficiency. Popular Mechanics did a test back in 2007, testing the big three -Chevy,Ford and Dodge- and the Chevy Duramax came out at 18.26 mpg. Now considering they are saying their diesels have 15-20% better efficiency you can bet the Duramax is better now than it was at the time of the test with best in class power.

Here's the link to the test.

I don't consider passenger cars in the diesel argument since they get mileage no matter what. The big 3 has always said the newest diesel out is always the best...in fact they are getting worse. The GM 6.5 turd diesel back in the 80's got close to 30, the 7.3 navistar got over 20, and there are still 5.9 cummins that get high 20's.....all those without the magical touch of computers and particulate filters....and in the cummins case, will make more horsepower than all the others hands down while maintaining the best track record of longevity. My best friend just bought a 2011 F350 and the first three trips out she got a dandy 10 mpg, my bro in law has an 08 Dodge with the 6.7 and it gets an awesome 12, and his dad has a 11 duramax and it gets a wonderful 10. Isn't technology wonderful? These arguments are exactly why I am building an old truck, with an old motor, that gets old mileage with no emissions requirments .....600 horse and 26mpg, I think that will suffice lol
