caseys 88 octane, anybody use it?

[pjtoledo]

update.
ran about 3/4 tank of the 88 stuff, didn't seem to be any different.

on the 2.3 Duratec I don't think there are any aluminum/zinc fuel system components so I'm not too worried about corrosion.

have since gone back to 87 10%
here's a video of the oil geek commenting on ethanol. yes, ethanol can affect oil.

EDIT: the owners manual says no methanol, has absolutely no mention of ethanol. just says use 87 octane unleaded.

Ditto on almost everything said. Before the fancy commercial real estate and international career, I ran the environmental engineering sections of my company and several companies before that. And I’m a ChemE. Back in the late 80s early 90s when all of the underground tanks had to be upgraded so they wouldn’t leak, in Atlanta there was also a huge issue with recapturing the fumes when the trucks unloaded, and when you filled your car. I worked a lot with the industry and the “government professionals” at that time.

Gasoline is a combination of about 240 chemicals. Ethanol would be one of those nowadays. Ethanol does not have the same energy release as the 240 mix, so they drop the price so theoretically you’re paying the same dollars per mile, and they could burn off “excess“ alcohol. And somebody said it, the alcohol production is subsidized, and man oh man don’t forget highway taxes! I once, behind closed doors, jokingly suggested to the head of the underground tank program. That taxes should be adjusted so you’re only paying the 90% for the gasoline, and not the 10% for the ethanol. Ethanol isn’t an additive, it’s a supplement. Georgia laws used to say highway taxes could only be taken from gasoline sales and only used for roads. I can’t even imagine what it’s legal to use it for now

It’s all a Shell game. All the vapor recovery stuff has gone away since they figured out how to re-blend the original 240 chemicals on a seasonal basis to cut down the emissions in the summer heat.

I run everything on E 10 (two 87s, 88 & an 97). The 78 460 has to run on premium, and the F250 is diesel. It all works fine. Anything that was made after about 1990 should, the operative word being “should.“. If you go a little bit further, like my 97, there are enough sensors and computer controls that it will burn almost anything without the truck running bad. But the more alcohol, the lower the mileage. I don’t know that for a fact from my truck, but I do know that is an absolute truth from my chemistry and engineering education.

Just my two cents, for what it’s worth

I am fortunate enough to be able to get non-ethanol 90 where I live. All my vehicles and equipment run better on it. It's a shame that it's not more readily available nationwide.

We also have ethanol free near me. Just a few miles down the road

After thought, but I got the 87, E 10 for $2.51 the other day. Woo hoo.

filled the 2000 FF with Sheetz 88 today.
first time it's had anything other than 87 in it for 10+ years.
this rig is driven less than 4000 miles a year so I'm not too worried about the side effects to oil.

My work truck is a flex-fuel F-150 and I've run E-85 and the E-15 Unleaded 88 in it. All I notice is lower gas mileage with either versus normal 87 gas. On the company fleet fuel card we're only allowed to buy 87 or the E-85 and E-15 because they are cheaper. In my personal truck, I run E-0 most of the time because it's quite readily available at Wawa, Circle-K, and Shell down here in FL.

For a truck that sits around a lot, I would be worried with that fuel in it.
