This is the difference between E5 and E10 fuel and which one you should choose to put in your car

You can fuel your car in a variety of ways, from petrol to diesel and now even electricity, but for some car owners, choosing which type to use can cause confusion.

We’re talking about both E5 and E10 fuels, and the real difference between the two.

Both the premium and standard gas types are available in different countries worldwide.

However, there is one big difference that you may not realize, and the revelation may surprise you.

You’re at the gas station, but are you choosing E5 or E10 gas?

It’s a question that you’ll often ask yourself when owning a vehicle, but not in the way you’d imagine. In fact, it simply means premium or standard.

In simple terms, E5 is generally your more premium fuel offering, and E10 is more basic.

One YouTube creator by the name of Conquer Driving explained the true difference between the gas types and which one you should choose.

The UK-based content creator explained that E10 is cheaper than E5 across the pond, but it doesn’t necessarily mean it performs on a lesser scale.

In fact, E10 fuel was reportedly introduced to cut emissions, with E10 containing 10 percent ethanol and 90 percent regular unleaded fuel, according to Foray Motor Group.

On paper, yes, you should be able to get better fuel economy from E5, but only if your vehicle is able to run on the fuel itself.

What’s more, the possible economic difference is only minor, with E5 providing 40 miles per gallon, and E10, 39.3 miles per gallon.

When it comes to the price, again, the difference is only slightly noticeable – in 2024, it came out at just 2.9 percent.

As ethanol is corrosive, though, you should only use E10 if your car accepts it, or your engine could end up severely damaged.

The creator’s own experience gave him one conclusion

After owning his Seat car for 10 years, the creator shared just how much he has spent on gas in his car.

Now, we should note here that he used the cheapest fuel possible and still spent around $41,937 (£31,000).

“Cheap fuel isn’t less clean than premium fuel,” he explained.

Now, of course, Octane levels come into play too, as E10 comes with an Octane of 95 in the UK.

E5, however, comes with a higher Octane level than can reach 99; these measurements mean the gas can take more before ‘spontaneously combusting’, this difference, though, is minor between the two fuel types.

So, if your car says premium gas, but on the cap also says Octane 95, E10 will work just fine.

There is a twist, though, and E5 fuel is recommended by the car expert if you don’t drive your car very often, as E10 has higher ethanol levels, which absorb water that can separate it from the gas.

So if your car can run on both, it’s ultimately down to you to decide which fuel type to use; if it requires one or the other, though, that’s different.
