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.
If you ran octane too low, the engine will knock (not terribly bad for it, but again a loss in power)..
How much HP does 93 octane add?
Switching from 87 octane to 93 yielded a 7-hp gain on the dynamometer, but that advantage was lost in the noise at the track.
Will higher octane run richer?
Octane ratings are plastered all over every gas pump, and, contrary to marketing terminology, “premium” does not necessarily indicate a fuel is “better” for your car as much as whether it is “right” for your car. Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly.
Is 100 octane fuel safe?
So, the moral of the story is; unless you have at least 12:1 compression (of more), do not run any 110 octane or higher race gas in it or you’ll go slower. If you have 10:1 – 11:1, you can run up to about 100 octane and be fine, but if you have in the 9:1 area, don’t even bother.
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.
Can premium gas hurt your car?
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. On occasion, this occurrence will likely not harm your vehicle.
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.
Is it better to run 93 octane?
Higher Octane Doesn’t Mean Better Performance Higher octane doesn’t always give better performance. … This means that your engine will be cleaned the same by 87 octane fuel as it will by 93 octane fuel, so don’t feel that it’s necessary to treat your car to a higher grade.
Do cars really need premium gas?
Some manufacturers recommend premium gas but say that regular or mid-grade gas can be used instead. They usually warn that using lower-octane gas could reduce performance and fuel economy. When that happens noticeably, or if engine knock occurs, they advise to start using premium.
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.
Does higher octane increase horsepower?
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. … Because higher octane gas burns slower, it is more resistant to knock when subjected to higher RPM and cylinder pressures.
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.
Will 93 octane hurt my engine?
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.
Is high octane bad for small engines?
Don’t Worry About Octane Small engines have low compression ratios, meaning they won’t likely benefit from anything special in the gas like a higher octane rating. Some premium fuels may actually make your equipment harder to start. So save your money and use regular gas.
Will mixing premium and regular gas mess up your car?
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 your car needs only the lower octane gasoline to run well, you won’t see any advantage in the slightly higher octane of the mixed fuel.
