Ethanol Enriched Fuel!?

[Gimli G35]

has anyone ever seen a gas station with it ? or even tried it?!

They are now saying that Ethanol ENRICHED gas is better than normal gas and actually allows the engine to run "better"

Isnt Ethanol enriched gas like half gas half ethanol .. How would it do on a car that has been ran on 93 Octane all its life?

Ethanol enriched fuel is only better when used in a high-compression engine, close to the ratios of a diesel. In engines today, you will see a pretty good decrease in gas mileage because ethanol contains less energy (about 34%) than conventional gas. Flex fuel vehicles that use E85 get terrible gas mileage, but its also said that E85 should be close to Premium although most vehicles can't use it. If you look in the manual, I believe somewhere it says to use gas that is <10% ethanol, at least for 2006 and older.

Nowadays all stations have a <10% ethanol mix, and if not it should be stated on the pump what the percentage is. Stations in Portland have to carry gas with >10% ethanol mix.

Here's a whole thing on fuels

great explanation , weird our Pistons can handle 102-104 Octane ohh well , the shops G is only 1 Octane over what the chart says it should use... damn 8.5:1 pistons!

Try acetone that stuff actually works. It is in almost all octane booster/ fuel cleaner. I used it several times. I am getting too lazy and stopped. I use octane booster.

did it increase gas milage for you ? Im not really trying to increase mileage or anything just curious because a gas station said they had it but didnt know the percentage .. got me worried

Im actually scared to add anything else than octane booster or fuel cleaner... add to much and something might happen

I have never used E10 before, however, I have noticed that I get better economy (up to an extra km per litre) with the same performance using BP Ultimate instead of Shell V-Power/Optimax.

I used 1-3 oz. per tank. I did not see any gain on the gasmilage or not much. I don't really care about it. It just running better with it. You have to watch your paint it can take your paint offf in no time!!

O yeah ! my brother owns a nail salon ( dont laugh , the salon is for his wife) ... well acetone is a key in getting paint out

"Ethanol enriched" fuel is just gasoline mixed with ethanol. E-10 is 90% gasoline and 10% ethanol. Any modern car can use it as long as the octane rating is high enough. E-85 is the other way around -- 85% ethanol and only 15% gasoline. Only so-called flexible fuel vehicles can run E-85 without problems. YOUR G35 CANNOT RUN ON E-85!!!

In the midwest, there are usually three grades of fuel. Unleaded regular has an octane rating of 87. Unleaded premium is 91 octane. Neither one contains ethanol. The third grade is E-10 based on unleaded regular and has an octane rating of 89.

Without getting into the renewable fuel debate, there is one argument for ethanol mixes and one against.

The argument for them is that ethanol has very high octane. Therefore, it will raise the octane of any gasoline commonly available at gas stations. For example, it adds 2 points to unleaded regular. If you can't find premium for your G35, regular with 10% ethanol would be better for it than straight regular.

The argument against is that ethanol contains 30% less chemical energy than gasoline. E-10 contains 3% (10% of 30%) less energy than unleaded regular. A car that gets 33 mpg on unleaded regular will only get 32 mpg on E-10. This difference is too small to detect on the road. My current cars (until my G37 arrives) were designed to run on 87 octane unleaded regular. Before filling up, I compare the prices of unleaded regular and E-10 and buy E-10 only if it is at least 3% cheaper than unleaded regular. If unleaded regular costs $3.00 per gallon, the break even price for E-10 is $2.91. E-85 has 25% less energy than unleaded regular; its break even price is correspondingly lower.

You can learn more about ethanol fuels in Wikipedia.

I have heard that there are a few places where all gasoline contains some ethanol. In such places, I would still run premium in a G35.

Ok , i actually did read about it already lol .. i think ill just keep away from Ethanol ... at least until i get a E-85 Car
