Anyone else running e15

They opened up a new gas station near my house and they offer e15. It's .10 a gallon cheaper so I only ended up paying 1.65 a gallon. I have run a couple of tanks thru the Cruze and gas mileage seems about the same. It does seem to have a little more power over the 87 octane I usually run since its a little higher octane. Seems like a good trade off and it's cheaper. Anyone else running e15

I would advise you to avoid the e15. It may be cheaper to fill up the tank, but that's because it has 15% ethanol in it. Ethanol will do nothing but bad things to engines. Although GM has said you will have no problems running e15, I hate using gas with more ethanol than is necessary.
The fuel system in the Cruze was designed for E10-15. Nothing more, though.
e15 is nothing new where I'm from. We've seen this stuff for almost 10 years in Michigan. It's actually pretty hard to find gasoline without ethanol these days.
I don't think E-15 is an acceptable alternative from GM's point of view......E-10, no problem.......E-15, no warranty for fuel related failures, per the manual......unless they changed their position.

The manual says fuels up to 15% ethanol content are acceptable.

OK then.....just re-read the 2012 manual for the ten thousanth time, heh heh.......yep, you are correct......fuels 'up to 15% ethanol'.....OK.

A day without learning something new is a day wasted......heh heh, you made my day.

If you check the owners manual all 2012+ GM cars and trucks can run UP TO E15 fuel. When this was first in the market in my area the blenders where starting with 87E0 gas, making it a 90 octane E15. However since the oil company's control the pipeline they are now only sending the ethanol blenders a low 84E0 to blend with making the E15 only 88 octane.

The old 90 octane stuff I had amazing power and my MPG on the highway(around 40mpg) was the same or better than the 93E10 I normally run. The new 88 octane stuff runs slightly better than 87 octane regular. Another issue is there is differences between each blender, my cruze likes my local stuff, but not stuff from another ethanol blender in the area.

Looking through my records I've run 340 gallons of E15 through my cruze over 3 years. Since I got the emissions update this spring however I've only run it once and my car really didn't seem to like it. It was July though and it is only 88 octane, so I may try again this winter. Its typically $0.60-0.70 cents a gallon less than the premium I typically run, but only about 10 cents less than regular gas.

Been running a mix of E85 and regular in our 2012 Cruze with no issues. It is nice paying $1.45 a gallon.
I'm surprised we haven't seen any ethanol production vs food argument on here yet.... Well just in case I figure I can help people with the real facts. When they produce ethanol the grains used were only every going to be animal feed. Even after they produce the ethanol one of the byproducts is something called DDGS which can be used as animal feed. Most if not all ethanol plants also trap all their CO2 emissions and sell for use in many industries.

Does this mean you support ethanol as a motor fuel?

The links are (naturally) pro.

I wish ethanol subsidies would die a slow, painful death. There is absolutely nothing good coming of them.

Only reason not to run ethanol fuel is if its a engine that gets stored for long periods. E10 fuel the entire USA uses is like taking 7 million cars off the road. My cruze runs noticeably better on 93E10 vs 91E0, unfortunately for me my state 99% of the stations have the 91E0 as the premium grade. When I say noticeably better that also includes having no engine knock occurring(monitored though the OBDII port) on hills where it does 100% of the time on the E0 fuel. You want to see your cruze fall on its face? switch from 87E10 to 87E0. One would think since the octane rating is the same it would run exactly the same, but that's just not the case.

I topped off my tank today with E15, figure if I'm going to be using remote start now that it's colder I'll save 65 cents a gallon over the premium I typically run. Why run expensive gas if I'm just gonna idle burn it? The 88E15 runs better in my car than 89E10 or 91E0, and 9 gallons today was a little over $17.

I asked your position because Illinois is considering banning the product.
Seems the emissions relating to the cosolvents required to maintain suspension are far rougher on the environment than straight gas.

That and the energy it takes to make it exceeds the energy it produces when all production steps are taken into account......that one is kinda old news though.

I do a ton of small (carburated) engine repair and the E-10 just tears them up....(fuel system damage....rubber, plastic).....nasty stuff.

As far as cars/trucks......I've several that require premium, several designed for regular, but the Cruze is the only car I've ever owned that has a fuel sensitivity that changes with temperature.

Anytime I ran across E-0 was summer, out of state travels so I was running premium anyways......no change between our E-10 and E-0 was noted.
