Premium gas, as opposed to regular, is a higher grade of fuel. It’s meant for high-performance vehicles and can cost as much as 50 cents more a gallon. Gas that meets Top Tier standards, on the other hand, has higher levels of engine-cleaning additives than non-Top Tier gas.
Does premium gas really make a difference?
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. 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. Premium gas is not “stronger” gas.
Does premium gas last longer?
Sadly, there’s nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn’t much of a threat on most modern fuel systems.
Is premium gas better than regular?
Regular gas has the lowest octane rating, Premium has a higher octane and Super (or Supreme or Premium Plus) has the highest octane. Octane is the measure of the fuel’s ability to resist “knock”. Putting premium fuel in a low compression engine or putting regular gas in a high compression engine.
Is it bad to put premium gas in a regular car?
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.
Will premium gas clean my engine?
Nope. Regular, plus, and premium gas all come with detergents to mitigate against carbon deposits in your engine. Plus and premium don’t come with special powers for cleaning out the engine. If you’re interested in cleaning out your engine, you’re better off taking it in for service.
What happens if 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.
Does premium gas give more power?
Contrary to popular belief, premium grade fuel does not contain more power than regular. The energy content of premium gasoline is actually a little lower than that of regular due to its additional anti-knock additives.
When should you use premium gas?
Required: If your car’s owner’s manual (or the inside of the gas door) says that premium gas is required, then you have to use premium to avoid damaging your engine. Recommended: When your owner’s manual (or the inside of the gas door) recommends premium you can still run your car on a lower grade fuel.
Does 93 gas burn slower?
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.
Why do some cars need premium gas?
Simply put, high-octane gasoline can be compressed and heated to a greater degree without self-igniting. That’s why high-performance engines use premium fuel. Since the engine doesn’t make quite as much power with low-octane fuels, this translates into slower acceleration in cars for which premium fuel is recommended.
Which vehicles require premium gas?
15 ‘Regular’ Cars That Take Premium Fuel Buick Envision (with 2.0L turbo) Buick Regal (all models) Buick Regal TourX (all models) Chevrolet Equinox (with 2.0-L turbo) Chevrolet Malibu (with 2.0-L turbo) Fiat 500L (all models) GMC Terrain (with 2.0-L turbo) Honda Civic (with 1.5-L turbo).
What happens if you put 87 in a BMW?
Regular gas is lower octane, usually 87 or 88. High octane fuel can withstand higher compression than lower octane fuels. Putting low octane fuel in a car with a high-compression engine could cause the engine to knock or ping, which could cause major damage if it goes on for a long time.
Does premium gas prevent carbon build up?
Branded gasoline, e.g. Shell, Exxon and Chevron, contain a larger concentration of detergent than required by law, and premium gasoline typically contain a higher concentration than lower octane rating gasoline. This higher concentration not only prevents carbon and gum build-up but also removes existing deposits.
What happens if you use higher octane fuel?
The higher the octane rating, the less likely a car will experience a “mistime combustion,” which creates the engine knock sound, according to The Drive. A higher-octane gas, such as premium, helps prevent engine knock.
Why is 88 octane cheaper than 87?
Q: Why is octane 88 priced lower than regular gas? A: Because of government ethanol subsidies, so the more ethanol in the gas, the lower the cost.
Does 93 octane add horsepower?
Premium gas must be, by law, at or above 91 percent, although you do also see 93 percent octane ultra-premium at many stations. Octane does not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only reduces the likelihood of engine knock or ping.
Does 93 octane gas last longer?
93 octane fuels are more refined and contain more stable hydrocarbons. These stable hydrocarbons can last 2-3 times longer than 87 octane fuel. Even in proper storage 87 octane gas can start to degrade in 3 months, 93 octane fuel should last closer to 9 months before degradation is noticeable.
