Retail gasoline stations in the United States sell three main grades of gasoline based on the octane level: Regular (the lowest octane fuel–generally 87) Midgrade (the middle range octane fuel–generally 89–90) Premium (the highest octane fuel–generally 91–94)
Which gas is better 87 89 or 93?
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.
Is 91 and 93 gas the same?
Is 91 and 93 gas the same? The short answer is no, but the long answer is that there are some major differences. While 91 and 93 both contain roughly 2.26% of TEL (lead), the actual octane rating can be different.
What is the difference between 87 and 91 gas?
Typically “regular” gas is 87 octane, “midgrade” is 89 octane and over 91 octane is “premium” gasoline. Some states label top-tier gasoline with 93 octane as “ultra” gas.
What happens if I use 89 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.
Is 86 gas the same as 87?
Higher mixes of ethanol. Low-octane fuel — rated 85 or 86 as opposed to the 87 for regular gasoline — is common in the Rocky Mountain states, said General Motors fuel specialist Bill Studzinski. The practice goes back to the days of carbureted engines, when lower octane helped vehicles run smoothly at altitude.
What happens if you put 87 in a BMW?
The short answer is – nothing. Most BMWs can run on regular gas so you aren’t at any risk of causing damage to your brother’s car. When you put regular gas in a BMW as opposed to premium, the car will recognize this and may run with a little less power and less timing but all components will work properly.
Does 89 last longer than 87?
Re: does 89 grade gas last longer than 87? There is absolutely no reason to run a medium octane grade or high octane grade of gasoline UNLESS THE ENGINE IS PINGING.
Is it OK to use premium gas instead of regular?
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.
Is 92 and 93 gas the same?
“Premium” Gas Can Vary By State
One state may require a minimum octane rating of 92 to be considered premium, while another may only require 90. Gas stations in the United States generally offer three octane grades: regular (usually 87 octane), mid-grade (usually 89 octane), and premium (usually 91 or 93 gas).
What gas is better 91 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.
What happens if you put 93 gas in a 87 car?
Can You Mix 87 And 93 Together? In addition to 95 octane fuel running through the 87 or 89 octane engines, you have absolutely no harm to your engine. The 93 octane fuel will not need to be run in any circumstances. In fact, it won’t improve how your car runs.
Does using 91 octane instead 87?
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. The purpose of the additive is to make the gas more resistant to pre-detonation, more commonly known as pinging or knocking.
What happens if I use 91 instead of 87?
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.
What happens if you put 87 instead of 91?
“Use premium unleaded gasoline with a posted octane rating of 91 or higher. 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.”

What Happens If You Mix 87 And 88 Gas? It shouldn’t matter if your car frequently uses 87-octane gasoline, which means it accidentally mixes 91, 92 or 93 octane fuel. Gas from different kinds of countries actually burns differently in an engine because it comes from one type of blend.
