Non ethanol mpg and performance

[Sherman Bird]

A minor point, and perhaps just indicative of different markets, but here in the Mid-Altantic, and during my travels throughout that region, all pumps have a label that
says "Contains up to 10% ethanol". Never knew quite what to make of that.

But I've been using either Top Tier or non-ethanol for several years now, both her Eclipse and my Ram.
I haven't seen anything that even hints at any additives in non-ethanol gas so I tend to switch back and forth, or I add Red Line SL-1 to a tank.

I can't think of a single fuel source I've seen that listed 15% ethanol, I wonder if there is one out there?

I've seen the 15% here in Houston in a few places, but it does seem to be a unicorn. The engine that e-10 is most beneficial for is the GDI engines. But, additives across the board DO matter. I doubt that ethanol free gas is "raw" gas, in that it would at least need to address knock (preignition) and acid formation from the combustion process.

Sherman: The reason you don't see much 15% ethanol, UL 88, is that
is dispensed through a blender pump, that also sells E85. Stations
do not have room for tanks only for UL 88, E10 is the norm. I find here, that there are only a few stations have blender pumps, maybe 10% of them.

As far as David above, he says he can feel the difference between 87 and 89 I call BS. C'mon man.......

The reason the label on the pump says 0-15% ethanol gives the
supplier the ability to switch between levels, in case of supply
issues, pricing issues, etc. I see no problem with that.

I've seen the 87, 89, Flex Fuel, and the Unleaded 88 but every station I've been to that has the UL 88 that pump never works. I can't remember when the last time was I saw 93.

I think Rick Tapp did some dyno testing comparing 87 /89 and 91 on a stock 5.7 and there was a noticable differance in rwhp between them. He used an untuned truck,so the tuning factor was ruled out.The only untouched thing i owned was my stock 300,and there's a very noticable differance in power between 87 and 91,enough my wife thought i'd tuned the car when i started filling it up with 91 instead of the 87 i'd ran it on for several years prior to using 91 in it.

I know someone that drives for a fuel company. He tells me that regardless of the gasoline brand, there is a quantity of fuel additive he mixes in the fuel load at the depot, and each brand he's delivering to has there own special additive.

Also, New York state has regulations on how many in-ground fuel tanks that a station can have, based on property size. Around here the mid-grades are blended as most stations only have a 87 tank and a 93 tank. You need a third tank for diesel, and another for kerosene.

Kerosene isn't sold in these parts at gas stations! I guess this means that a 737 will still have to go to the airport for fuel around these parts! LOL!

Kerosene isn't easy to find around here anymore. Tractor Supply has (had?) it in one gallon cans. I was surprised to see it lately at a Speedy gas station on the west side of Rochester.

Interesting, I have never seen kerosene at a gas station.

I didn't feel a difference between 87 and 89, sorry I gave that impression. I felt the performance difference and saw an increase in mpg from 93 E10 vs 88 non-ethanol.

I started with 87 E10 3 years ago, when purchased new, because the sales guy said it was fine. I quickly changed to 89 because of recommendations in the manual and such. But shortly after that, I just went to full 93 because I started buying gas at Sam's, and they only sell 87 and 93. I noticed an increase in mpg with 93. In fact, the increase in mpg, as a percent, out wade the percent increase in price. And now... with 88 non-ethanol at the same price as 93 E10, I figured I'd go with the increase in mpg and "my" noticeable increase in performance.

That’s not the case around here at SAMS any more. Their 93 premium is almost 80 cents more per gallon than 87 regular ($2.62 currently). I would have to get 30% better mileage to break even on that.

Sam's is NOT a top-tier fuel around these parts, historically. My customers who decide that I'm just a blathering idiot when I preach top-tier fuel for the betterment of their cars, are the ones who keep me in the work load I have due to more frequent spark plug issues, contaminated Oxygen sensors, bad/failed catalytic converters, injector problems, and carbon/sludge in their engines. It may be better than that where you are, but I seriously doubt it.

ok... then keep using 87. I saw about 20% increase, from 15 to about 18 mpg. If remember right, that was about the price difference, from about $3.10 and to about $3.70 or so. Anyway, I'm using the non-E now for the reasons stated above.

 

[Rado]

I run Non Ethanol now and then on my Pentastar ! Not a big difference maybe 1 to 2 mpg more !
I run Top Tier Shell or Mobile ! Now and just started to add some Techron ! That seemed to help the MPG as well

I do use Non Ethanol in my Snow Blower.Mower and chain Saws and generator

I’m not calling you out on it. Up until a few years ago I drove a Shelby GT350 that required premium and I believe it was usually just $.40 +/- higher than regular and that didn’t really bother me any as I didn’t drive a ton of miles anyway. It was also cheaper than anywhere else I could buy premium. But SAMS seems to have really increased the price differential between regular and premium in recent years which has hurt the benefits in using it.
