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 higher octane hurt your engine?
The higher the octane, the greater its ability to prevent the unruly type of combustion engineers call detonation. The goal is to ignite the fuel mixture solely with the spark plug, rather than from the heat in the cylinder, to prevent detonation, which can seriously damage high-performance engines.
What happens if I use 87 octane instead of 89?
Using a higher octane than necessary If you opt for a higher octane than your manual recommends—say, 89 instead of 87—your car will be perfectly fine, an article on AAMCO’s blog explains.

Will regular gas damage a premium engine?
The key for drivers is to know whether premium gas is merely recommendedfor their car or if it’s required.

What happens if you put 87 octane in a Mercedes?
87 Octane. Although 91 octane is recommended for a majority of Mercedes-Benz models, it is not extremely harmful to put in 87 octane. This lower grade octane will not maintain the vehicle’s performance level, but it will not harm the engine because the computer system will know that the fuel is of a lower grade.
What happens if you 87 instead of 91?

Premium gas gives you more miles per gallon than regular gas. … In actual fact, you’ll get a greater range of fuel economy between different brands of regular gas, than you will between the same manufacturer’s regular and premium gasses.
Is premium gas worth buying?
Typically, high-performance cars require premium, because their engines have higher compression ratios, while other cars can run just fine on lower octane gas. … The FTC sums it up this way: “In most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit.”
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.
Will regular gas hurt my Mercedes?
While regular unleaded gas shaves a few dollars off filling up your tank, Mercedes-Benz engines require premium gas due to their high-compression ratios. This means using regular gas may lead to costly repairs. To avoid more repair bills outside of scheduled service, you should always fill up with premium fuel.
Can you run 87 octane on a 93 octane tune?
87 is the standard octane rating that most car engines are designed for. … The reason why you should never run a lower octane fuel on a vehicle tuned for higher octane fuel is because the tune has no way of detecting what fuel you are using and will continue to operate assuming you put in the correct fuel.
Does premium gas clean your engine?
No matter what you’ve heard, premium-grade gasoline won’t do more to clean deposits from your fuel injectors or other parts of the fuel system because today’s regular gas contains the same detergent additives. The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane.
Can you mix high octane gas with regular gas?
“I see no benefit in mixing.” Higher octane gasolines are designed to burn more slowly and produce a uniform flame propagation in your engine’s cylinder – they’re meant for inside a high compression engine where regular gasoline might start burning before it’s supposed to and cause engine knock.
What happens if you mix 87 and 93 gas?
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.
What happens if you put 88 instead of 87?
A: Unless the owner’s manual says your car can handle 15 percent ethanol, you could harm your engine in the long run. The 88 octane should have no effect if you happened to fill you tank with it once, but prolonged use by a car not equipped for it can cause an engine to wear out faster.
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.
