Eco 88 unleaded

We have some Sheetz that have blue nozzle E15 88 Octane (I actually posted about it almost 5 years ago E15 Fuel vs E10 Fuel, damn it makes me miss my Focus again…). I haven’t purchased a single drop of the E15. I’d have to check my Camry’s manual, but I’m pretty sure my wife’s Escape (2014) is ok with E15. Still the price discount per gallon isn’t enough lower considering the mpg drop.
