Flex Fuel (E85): Why This "Green" Gas Never Went Mainstream

So there's this fuel called flex fuel that's been around forever, and honestly, most people have no clue it exists. It's also called E85, and it's basically regular gas mixed with a bunch of ethanol. Think of it as gasoline's hippie cousin that never quite made it mainstream.

Ford started messing with this stuff back in the '90s, and for a while, everyone was jumping on the bandwagon. GM, Toyota, even the fancy German brands were like "yeah, let's try this ethanol thing." Now? Not so much. But there are still a ton of these cars driving around, and people probably don't even know they own one.

What's the Deal?

Flex fuel is basically gasoline that's been mixed with ethanol - sometimes up to 85% ethanol. The whole point is that these special cars can run on this mixture, regular gas, or whatever's in between. The car's computer is smart enough to figure out what you've dumped in the tank and adjust everything so it doesn't blow up.

It's not like you need some crazy different engine either. These flex fuel cars are pretty much normal cars with a few tweaks to handle the ethanol without everything falling apart.

Why People Thought It Was Cool

Back in the day, this seemed like a pretty good idea. Ethanol burns cleaner than regular gas, so it's supposedly better for the planet. Plus, it's made from corn and sugar cane instead of oil, which sounds way more sustainable when you put it like that.

The cars are actually pretty clever too. Since flex fuel comes in different strengths, the car just figures out what you've got and rolls with it. No need to hunt around for some specific blend like you're shopping for artisanal coffee.

Oh, and the government used to throw some tax credits at people who bought these things. Free money for being environmentally conscious? Sign people up.

Reality Bites

But here's where it gets ugly. Ethanol might be cleaner, but it's also a total gas hog. People usually see their fuel economy tank by 15-25% when running E85. That Pontiac G6 from 2009? Went from 23 mpg to a pathetic 17 mpg. Ouch.

And good luck actually finding the stuff. Out of nearly 200,000 gas stations in the country, only about 5,600 sell E85. Try explaining that to someone stuck in the middle of nowhere with an empty tank.

The ethanol is also kind of a pain in the ass for engines. It loves soaking up dirt and grime, and it's tough on rubber parts like fuel lines. Older flex fuel cars especially tend to have more problems, which is probably why used car lots aren't exactly advertising this feature.

Cars That Actually Had It

This wasn't just some niche thing either. Ford put flex fuel in everything from Explorers to F-150s. Chevy had it in Suburbans, Ram stuck it in their 1500s. Most of these cars looked exactly like their regular counterparts, maybe with a tiny badge that nobody notices.

The Harsh Truth

Flex fuel seemed like it could be the sweet spot - cleaner than regular gas but without all the drama of hydrogen cars or the range anxiety of early electric vehicles. But between the terrible fuel economy, the fact that you can't find it anywhere, and the potential for engine headaches, it just never caught on.

These days, it's basically automotive history while everyone's obsessing over electric cars and synthetic fuels. Sure, if someone lives next to one of those rare E85 stations and doesn't mind burning through fuel like it's going out of style, knock yourself out. For everyone else, it's just another reminder that there's no such thing as a perfect solution when it comes to what we put in our gas tanks.
