Is E85 Gas The Same As 87

Ever found yourself at the pump, squinting at those numbers on the gas pump, wondering, "Hey, is E85 the same as 87?" Well, you're not alone, my friend. Let's dive in and clear this up, 'cause it's actually pretty interesting!

First things first, what's the deal with those numbers?

You've got your 87, your 89, and then there's E85. They're all talking about the same thing, right? Sorta. They're all talking about octane, which is a measure of a fuel's resistance to combustion. But they're not all the same.

So, what's the 87 and 89 about?

The 87 and 89 refer to regular and premium gasoline, respectively. They're both petrol, which means they're made from crude oil. The difference is in the octane. 87 has a lower octane rating, while 89 has a higher one. Think of it like a spicy food scale - 87 is mild, and 89 is medium. Still with me?

Now, let's talk about E85. What's the 'E' stand for?

E85 is a type of ethanol-based fuel. Ethanol is an alcohol made from plant materials like corn or sugarcane. The 'E' stands for ethanol, and the '85' refers to the percentage of ethanol in the fuel - it's 85% ethanol and 15% petrol.

Why's it so special?

E85 is special because it's a renewable resource. Unlike petrol, which comes from finite resources like oil, ethanol can be made from plants that grow back. Plus, it's often made in the U.S., which can help reduce our dependence on imported oil. Pretty cool, huh?

But is E85 the same as 87? Spoiler alert: Nope!

While they're both fuels, E85 and 87 are quite different. E85 has a lower octane rating than 87, coming in at around 83. This means it's less resistant to combustion. But don't worry, your car won't explode if you put E85 in it - it just means you need a special kind of engine to use it.

Flexible Fuel Vehicles (FFVs) to the rescue!

FFVs are cars designed to run on either petrol or E85. They have special fuel systems and engines that can handle the lower octane rating of E85. If you've got an FFV, you can fill 'er up with E85 and enjoy that renewable fuel goodness. But if you don't, stick to the petrol - your car will thank you!

So, why isn't everyone using E85?

That's a great question! E85 has some awesome benefits, but it's not without its challenges. For one, it's not as energy-dense as petrol, so you'll go through more of it to get the same distance. Plus, it's not as widely available - you might have to hunt for a station that carries it.

But as more people learn about the benefits of E85 and more FFVs hit the road, we might see it become more popular. Who knows? Maybe one day, E85 will be as common as 87. Until then, it's still a pretty neat option for those who want to try something different at the pump.
