Are 91 and 93 octane the same?
Premium gasoline is generally considered any type of gasoline with an octane level of 91 or greater, with 91 octane and 93 octane being the most common versions of premium gasoline available at gas stations in the United States (93 octane gasoline may be called “ultra” or “super-premium” in some cases).
Does 93 octane really make a difference?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. 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.
How much HP does 93 octane add?
There is no difference in HP between 91 and 93 octane UNLESS you have had your car tuned for 91 octane but can NOW get 93 octane. Well just putting in the 93 octane won’t give you any more HP. You need to get the car retuned for the higher octane gas.
Is 93 octane good for BMW?
BMW requires 91-octane fuel at a minimum, with 93 recommended, so we did just that, switching between the common forms of premium gas depending on which state you’re in.
Will 93 octane hurt my engine?
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 93 octane make your car faster?
The higher octane of premium gas won’t make your car faster; in fact, the opposite is possible because higher-octane fuel technically has less energy than lower-octane fuel. It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.
What is the difference between 91 octane and 87 octane gas?
Two common octane ratings are 87 and 91. The main difference between 87 and 91 octane gas is just the additive that they add to it. They are still the same unleaded gasoline that will work on your car.
Does 93 octane gas have ethanol in it?
Some does and some doesn’t. Ethanol raises the octane rating so addition of ethanol to an 87 octane blend can give you a 93 octane. But ethanol has a lower energy density than isooctane, so you don’t get as good a milage and you can have problems with corrosion or gasket failure in the fuel system in older vehicles.
The Difference Between Premium and Regular Gas. Simply stated, premium gas has a higher octane level than regular gasoline. The octane rating of gasoline determines how likely it is for engine combustion to occur at the wrong time.
In most states premium gasoline is defined as gas having an octane rating of 91 or 92 — regular typically has an octane rating of 87.
