10% Ethanol OK to use??

2008 G35x.......Owners manual says to use no more than 5% Ethanol. Until the recent hurricanes that was not a problem, I was able to find fuel without Ethanol in it. Now with the the panic buying here in Nashville All I can find Is gas with 10%. I don't really expect to find much else for awhile either. Will that hurt my engine or not??

all gas here in Colorado is 10%, so i am sure you will not have a problem running it seeing that all my car sees.

Gonna have to be. States are starting to mandate it...

Have you found somewhere that still have 100% gas? Costco was my last hold out until about 2 months ago.

Ethanol is good, raises the octane rating,

E85 is a awesome race fuel

Ethanol is ****ty.

All octane ratings are are an indication of how combustible a fuel is (so early combustion = pinging).

Ethanol has lower stored energy than gas or MTBE and thus, on a stock car, you get less MPG and power on ethanol gas than straight gas.

Ethanol also eats rubber and plastic parts and I forsee quite a few cars with fuel system issues over the next few years.

Bigger picture, Ethanol production and distribution is FAR worse than the same for gasoline. Corn and sugar cane production for ethanol is causing pressures on food supplies and is directly responsible for the increased deforestation in Brazil. Since it can't be pipelined well in the current infrastructure, it must be shipped long distances in smaller containers.

Ethanol is also hydroscopic, meaning the longer it sits in a tank somewhere it picks up more water -- BAD!

And talking to a few people that actually are delivering the gas, it seems that some companies are taking 89, adding Ethanol and calling it 91 octane gas (since it does increase the octane rating). Bad and unscrupulous since ethanol costs less than gas, the price should be lower.

For vehicles that are converted to E85 (which is a common modification to Evo VIII and IX's), they typically have to replace quite a few fuel system components: fuel pump, injectors, lines, filters, etc. because ethanol requires more volume and pressure in order to produce the same or more power.

KEEP ETHANOL OUT OF MY GAS

Ethanol SUCKS!

This is what happens when politics take over a free market. You end up with crap like Ethanol.

Alternative fuels? We SHOULD pursue them, when the market calls for them and they make financial sense.

Sure, solar and wind power sound nice, neat, and clean....... but I don't want a $1000 electric bill. Keep the politicians away from my car. They're already killing all the cool cars with the CAFE standards and hurting my car with ethanol..... what's next?

well part of ethanol is politics for sure! but the MTBE that was in the gas was leaching out of the tanks and getting into the groundwater, causing lots of issues with water supplies.

exactly why Ethanol is good, it raises the octane ratings, IE less ping with the same compression and timing. which allows you to advance the timing and raise the compression the get more power out of engine

like i said, its a good race fuel

correct, normal cars are not designed for Ethanol, you have to change a few things. but once you do make those changes, Ethanol becomes a better fuel because you can run ur engine at 200 + PSI compression and get more power. which is exactly why the evo kids are doing it.

you can also look at it another way, as you stated with a stock car, u get less mpg, but as you also stated Ethanol is cheaper, so if you look at you cost per mile, not cost per gallon, it comes out to be the same, depending on the Ethanol %, its some times better.

hence why you have to change a few things to go to e85, right now ur running e10, e10 has been around for 5-8 years, any problems yet?
what you might not know is gas stations are not required to tell you if there is less then %10 Ethanol in the gas. so for all you know you could have been burning it for the last 5 years.

Ethanol is an awesome solvent, it keeps your engine clean, it’s highly similar to injector cleaner.

which is all correct.
but Ethanol is also renewable, and it burns MUCH cleaner. its a good supplement, not a replacement.
there is no one silver bullet for the world to get off of oil, its going to take multiple types of renewable fuels.

they have been doing that for years with other additives, like on the order of 30-40 years



Ethanol is in ur gas, and will be for a LONG time, car manufactures have already bought into it, and so have the feds. you are basically going to have to deal with it.

is it better then gas, depends on how u look at it.
but like you said, given the current infrastructure, its cheaper then any other supplement we have. and with some simple modification to cars, after market or more increasingly at the factory, its the best choice we have.

and like my original statement, its an awesome race fuel.
and as you put it, its cheaper.


we can debate why it is good and bad till we are blue in the face, because it has good and bad points. but as every one knows, we are stuck with it. and because its the new mandated fuel blend, the manufactures have to design cars to run it.

has any body seen any problems from running it?

Another thread I found on Ethanol on a different forum while googling:

http://www.6mt.net/forum/g35-coupe/2...m-gas-bad.html

I think that general consensus is Ethanol is bad for cars that aren't specially modified for it (including the G?), but most of the gas stations in my area have ethanol in their gas.

Our cars can compensate for E10, most four stroke engines are fine to run off of it. Where the only real problems from E10 pop up are in two stroke engines that require mixed fuel. The solvent capabilities are too much and will tear up the engines because there is not enough lubrication.

My problem with E10 is the decrease in mileage. Since there is less energy in it than gasoline it will decrease your mileage. The decrease should only be about 3% but in my personal experience it is closer to 7%.

I have a Ford Ranger that can run on E85 that gets averages 19.5mpg on gas, just over 18mpg on E10, and 12mpg on E85. Based on the cost of E85 in my area, gas or E10 are more economical to run than E85. However, the truck runs MUCH better on E85, it feels like a few additional HP off the 100+ octane it provides.

I have no choice but to use 10%... can't find anything else around here.

My wife's Acura MDX states in the manual that it is not recommended for use in the vehicle.
We have no choice though.

Most gas suppliers add more ethanol in their gas during the winter months in the colder states.

Ethanol kills old Nissan injectors. My Q45 is parked waiting on at least two injectors, but may have to replace all eight ($3000). I hear ethanol is really bad news for boats.

If a gas station doesn't have a sticker on the pump about 10% ethanol, only the sticker is missing.... not the ethanol. It's a local mandate, not an option.

Ethanol is crap, just as MTBE was, which is now outlawed. I puke all over myself every time I see a car/truck with the words 'Flex Fuel' written on the back. It's just another way for the gov't to try and make themselves feel better while not accomplishing a thing except making our fuel mileage even worse but pulling 10% of gas out of every gallon and replacing it with crap, so we're using basically diluted fuel..... hey, i have an idea. let's put 10% water in every gallon, there's zero pollution with the water, so surely it must work better than anything else; great for the environment.
