Pulling up to the gas pump these days feels like prepping for a pop quiz in economics, especially when those premium gas prices hit you in the face. Yikes!
We’ve all been told that quality beats quantity, but does that rule apply to gas too? What’s up with premium gas anyway? Is it worth the extra cash, or just another slick marketing ploy to empty our wallets?
Time to spill the beans, so buckle up and let’s break it down!
What’s Premium Gas Anyway?
Alright, here’s the lowdown. Premium gas is all about that octane life. When you roll up to the pump, you’ll spot three choices: regular (87-octane), mid-grade (89-octane), and premium (91-octane and above). Higher octane sounds fancy, right?
But let’s be real. Most of us just go for the cheapest option. So, is premium really worth it? What’s the big deal?
How Does Premium Gas Differ From Regular Gas?
The main differences between premium and regular gas boil down to octane rating and price. According to the U.S. Energy and Information Administration, premium fuel is about 60 cents more per gallon than regular gas and 25 cents more than mid-grade.
So, why drop extra coin for premium gas? It’s all about that octane game. Here’s the scoop: Regular gas is a byproduct of crude oil with an 87-octane rating. Premium gas, also from crude oil, has an octane rating of 90 or higher.
Higher octane means premium gas can be better for the environment. It creates less pollution and keeps your engine and emissions system cleaner and more efficient. But what’s all this octane jazz about?
What Does An Octane Rating Mean?
An octane rating measures how well the fuel resists knocking during combustion. Starting a gas engine takes a lot of energy and heat. When an engine fires up, it mixes air and fuel, ignited by a spark plug, creating a lot of energy and heat (combustion). If this happens without the spark plug, it makes a noise called knocking. This noise isn’t just annoying—it can mess up your engine’s pistons and cylinders.
Using the right octane level prevents this noise and stops the air-fuel mix from igniting on its own, saving your engine from potential damage. Higher octane means the fuel can handle more heat and energy from combustion, boosting fuel economy and protecting your engine and emissions control system if you stick to the manufacturer’s recommendations.

Is Premium Gas a Gimmick?
Now that you know what an octane rating is, you might wonder if premium gas is just a gimmick to get you to spend more at the pump. Not all cars need premium gas, right?
Premium gas can feel like a gimmick if you think it’ll magically boost your gas mileage. If your car’s engine doesn’t call for premium gas, you probably won’t see any benefit from using it. Overall, premium gas isn’t a gimmick if used when needed.
The Benefit of Premium Gas
If your car’s manufacturer recommends or requires premium gas with high octane levels, there’s a reason for it. Engines designed with turbochargers or high performance need higher octane to perform at their best. Newer cars or big, heavy-duty trucks might need premium gas. Check your owner’s manual or the inside of your gas tank door for the deets.
Even if your car doesn’t require premium, there are times it could help. When towing heavy loads or when your engine is working harder than usual, higher octane fuel can make a difference. But under normal driving conditions, stick to the manufacturer’s recommendation.
When Should You Use Premium Gas?
Still not sure when to use premium gas? Do it if the manufacturer requires it. This will give you the best performance and fuel efficiency. Using lower than required octane fuel can damage your engine over time. Using higher than recommended octane won’t hurt your car, but you probably won’t see any fuel efficiency gains.
Is Premium Gas Always Better For Your Car?
If the manufacturer says use premium, do it. High-compression engines, turbochargers, and other high-performance components need fuel that can handle more heat and energy.
If you’re cool with cheaper, lower octane fuel and the manufacturer only recommends premium, see how your car performs with both. If there’s no difference, go for the lower octane—it’s better for your wallet.
Don’t Fall for Gas Pump Hype
Premium or regular gas? Choosing the wrong one could mean nothing, or it could mean a pricey lesson when you’re budgeting for engine repairs.
But it doesn’t have to be tough. If your car doesn’t need premium, save your money. It won’t make your car perform better.
If the manufacturer requires premium, spend the money at the pump to avoid spending more at the shop. If it’s just a recommendation, experiment and see what works best for your car.
If regular gas works fine, use the savings for new tires. They’ll definitely boost your car’s performance, just like using the right fuel will.

As was stated, follow your vehicle manufacturers recommendations. I pull a TT with a 2014 F150 with the 3.5L Eco-Boost. When pulling the TT I always use the highest Octane gas that I can find. Because turbos create a lot of heat, the higher octane fuel helped quite a bit in many ways. Better milage, less overheating issues on long or steep pulls, better performance, etc. I am not sure if my owners manual recommends or not as to using the higher octane but, I have done a lot of research to find out how to reduce the overheating issue the occurs with the Eco-Boost when pulling heavy loads. Discovered informations similar to the points made in this article that in the end proved to be substantiated by the lessening of overheat problems that I had encountered before starting to use the high octane fuels.
Just read this article. Roy is right on in his post. I had a 2018 and now a 2022 F150 with the Eco-Boost engine, 10 speed trany and 3:55 rear end. I also use premium when pulling our 5300 lb TT. Get great gas milage, generally, between 12-14 mpg at highway speeds (65-70 mph). Both engines ran/run cooler which good news.
