How does octane affect engine performance?
An octane rating, or octane number, is a standard measure of the performance of an engine or aviation gasoline.
The higher the octane number, the more compression the fuel can withstand before detonating..
Is it OK to mix 89 and 93 gas?
No, you will not damage your engine by mixing different octane fuel. It is still fuel. Say you mixed 2 gallons of 87 octane with 2 gallons of 89 octane and 2 gallons of 93 octane.
Does premium fuel increase mpg?
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.
Will 100 octane hurt my car?
Yep running on pure octane will not hurt the car. It will have slightly less power and fewer MPG but will run just fine. … High compression engines need high octane fuel. Putting high octane fuel into a low compression engine will not make it a high compression engine.
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.
What happens if you mix premium and regular gas?
It probably won’t hurt anything. If your car requires regular gas, the blend will have plenty of octane and detergent and may even run a little better or get a bit better mileage. If the car requires premium, the blend won’t have as much octane as it should.
Will running lower octane damage engine?
If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.” … They usually warn that using lower-octane gas could reduce performance and fuel economy.
Does 98 octane clean the engine?
Octane is the measure of a fuel’s ability to resist the phenomenon known as ‘knocking’, not its cleaning ability. Knocking is the uncontrolled combustion of fuel that can destroy engine internals.

What happens if I put higher octane fuel in my car?
But take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage, or run cleaner.
Does high octane fuel burn hotter?
Higher-octane fuel does not burn hotter. It will not clean out deposits from an engine combustion chamber. And it will not provide any higher fuel economy. But an engine’s octane rating can change over time.
What happens if you put 93 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 may feel a difference in the way the vehicle runs and may notice an improvement in gas mileage, but that’s about all that will happen.
Does 95 octane give better mileage?
Depending on your vehicle you should, in theory, get better mileage and fuel economy from a higher octane fuel (so 95). However, in the highveld you have approximately 20% less atmospheric pressure than at the coast – which makes it harder for fuel to ignite.
Which gas is better 87 89 or 93?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
Will 93 octane increase HP?
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.
