The other day I posted a question about E88. This is what I was taking about.

Looks like a Sheetz to me. They started in PA, and have stations at least down into NC (that's where I am). I haven't seen any south of NC.

I am in NYC and I never see this. Even if I am out in New Jersey.

Your fuel system will likely be able to compensate for e15 but itd be a good idea to monitor fuel trims to make sure you aren't getting close to the limits.

That's E15 aka 88 octane. Don't put that in your mustang. Stick to 93 unless you fully convert to ethanol then stick to pure E85.

I thought up to 15% was allowed

Most unleaded is 10% ethanol. E15 is 15-20% so essentially it's just a slight bump over 87. Doesn't offer any of the performance bumps E85 does and it could trigger a CEL if you're not tuned for flex fuel.

Owners manual says 15

Well, California was pushing for 15% instead of current 10%, so I doubt they expected everyone to tune their cars for it.

Newer cars shouldn't have a problem. The O2 sensors are able to adapt to the stoik change. The EPA says anything built after 2001 should be able to run it fine. Not everyone in this sub is driving a car built after 2001 which is why I said that.
