Is ethanol free that much of a difference...

dang370z · 10-28-2010, 11:18 PM

So I was just curious does ethanol free gas make a difference on your car. Is it also worth the extra 10 cent from name brand gas (shell, chevron, etc.) that has ethanol in it.

I go for Chevron bcoz of the Techron. That stuff works.

It's worth it to me. I get roughly 2-3 more MPG with ethanol free gas than the 10%E junk. At $2.85 for 93, it works out that I save money by using ethanol free.

I haven't ever noticed a power difference though, only MPG.

Ethanol hurts mileage.
E85, if your car is converted to run it, burns VERY clean and allows for a lot more compression.

A converted E85 car will make around 15-20% more power than it's counterpart (provided you take advantage of the extra compression on the table) and get 2-3mpg less (depending on gear ratios, etc.). This is just an observation of mine looking at the Z06 guys who have converted to run it.

what brands don't have 10% ethanol?

From where I live, we can choose ethanol free gas (which cost about 20% more than E10 due to local tax). The gas mileage is noticeably better when filling up with ethanol free gas.

I worked at gas stations 20-25 years ago and there was 10% in the gas at that time.

+1 as well.

Maybe its a State thing, but I have never noticed any places advertising that they had ethanol free gas. If they did exist, I'd love to know about it.

Thanks for that. I'm gonna give it a shot.

Jeffblue · 10-29-2010, 12:42 PM

no hope for us in long island new york, not a single station.

If you can buy ethanol free, do it. Ethanol reeks havoc on rubber in the fuel system and from my experience as a mechanic since it came out, causes way more harm than good. All the political non-sense aside, ethanol free > e85 or 10%.

TreeSemdyZee · 10-29-2010, 12:51 PM

Crap. I just checked the two stations listed on that site and there were notes on both that the gas tested with alcohol in it. I thinks there's a whole lot of lying going on at stations that say they have pure gas.

6spd · 10-29-2010, 12:53 PM

I could have swore there was a new law that said all station have to have 10% ethanol fuel, but Im not be 100% sure.

FERRARI · 11-09-2010, 03:58 PM

I guess I am lucky....I have at least 5 places within 15 miles that sell 100% gas
