Does high test gas make a difference?
So is Higher Octane Fuel More Efficient? In a word, no. On its own paying for premium gasoline does not make your car run better or get greater gas mileage. Giving your car the fuel it requires to run smoothly and efficiently, without damage to the engine, does make a difference in your fuel mileage.
Is there really a difference between regular gas and premium gas?
Premium Gas
When you compare premium vs. regular gas, you’ll notice premium gas is more expensive; but it’s beneficial for certain vehicles. The difference between premium and regular gas is the varying octane levels in each gasoline. Premium gas has an octane level of 90+ and will help to keep your engine cleaner!
Will high test gas hurt my car?
Let’s start with the easy one. Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.
Does high test gas last longer?
No, premium gas does not last longer than regular gasoline in a fuel tank. A car owner might only consider the longevity of a car’s gas if the vehicle has been sitting unused for an extended period.
Is it OK to put premium gas in a regular car?
Typically, “regular” gas is 87 octane, while anything over 91 octane is considered “premium” gasoline. A spokesperson with the American Automobile Association told FOX Business that it is safe to use premium fuel in your vehicle even if it takes regular.
Can higher octane hurt your engine?
It won’t hurt the engine, nor does it require a higher octane. If you hear a heavier or ongoing knock, however, don’t ignore it. Make the switch to the next higher grade octane and see if that takes care of it. If the knocking persists, see your trusty mechanic.
Is there a downside to using premium gas?
Con: Premium gas can be much more expensive.
Because of premium gas benefits, this fuel is typically far more expensive than standard gas which, for the average American, can be a pain-point.
Is it OK to put regular gas in a premium car?
Can I put unleaded fuel in a car that takes premium? According to Fuel Express, you can put regular gas in your car or truck even if the manufacturer recommends premium. But if they require premium, then pumping unleaded might cause issues.
What happens if I put high octane gas in my car?
The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging.
Which gas gets the best mileage?
premium gas
Premium gives better gas mileage
Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.
What happens if you mix 87 and 93 gas?
However, when you mix two different octane levels, you get their average. So, if you have exactly half a tank of 87-octane gas and half a tank of 93-octane gas, then you’ve just got a full tank of 90-octane gas. Adding higher octane gas to an engine designed to use lower octane gas will never be a problem.
Will premium gas clean my engine?
Today’s premium fuels contain additives and detergents that help clean fuel injectors and remove carbon deposits inside of engines, thus, incentivizing motorist with engines that use regular fuel to, on occasion, use premium gas to clean their engines.
What happens if you put 93 instead of 87?
In most cases, the vehicle will run fine, but you may experience less power and a decrease in gas mileage. In more serious cases, you may hear engine knocking or valve chatter because the fuel isn’t burning right. These things could damage your engine and you should take it to your mechanic.
Do you get better mpg with premium gas?
Premium gas has a higher resistance to engine knock in luxury and performance vehicles with turbochargers or high-compression engines, so you can hit that horsepower smoothly. Additionally, premium gas can increase fuel efficiency, potentially bringing better gas mileage for longer while decreasing emissions.

What happens when you put 93 gas instead of 87?
If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.
What happens if I run 93 instead of 87?
What happens if u put premium gas in a regular car?
Putting Regular Fuel in a Car That Requires Premium
Using lower octane fuel in a vehicle that requires premium gas could cause some serious internal damage. You’ll most likely notice the spark knock (a sort of high-pitched pinging or rattling noise).
Does driving slower save gas?
Slow Down and Drive Conservatively
Speeding increases fuel consumption and decreases fuel economy as a result of tire rolling resistance and air resistance. While vehicles reach optimal fuel economy at different speeds, gas mileage usually decreases rapidly at speeds above 50 miles per hour (mph).
What wastes the most gas in a car?
Driving too fast.
Most American cars operate at peak efficiency—generating the most forward momentum with the least amount of fuel—between 50 and 60 miles per hour.
Does using the AC waste gas?
When you’re taking full advantage of your vehicle’s air conditioner on a hot day in San Francisco traffic, you may wonder, does car AC use gas? Yes: The alternator, which is powered by the engine, is what provides energy to the air conditioner. The engine runs on fuel, meaning you are using up gas when you run the AC.
