What happens if you put 87 gas in a 93 car?

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 93 octane required for most cars?

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.

Can I use 89 instead 93?

Generally you will only feel a difference if the car is designed for 93 octane fuel, and you are using 89. In this scenario, the Ecu will retard the ignition timing to mitigate knock. This will reduce power and fuel economy(but will protect your engine) to a level that can usually be felt.

Is shell premium gas 93 octane?

I prefer to use 93 octane (or the highest available) at commercial gas stations because they tend to contain higher quality fuel. The ‘top grade’ fuels, such as ‘Shell V-Power 93’ and ‘ Chevron with Techron 93’ have better additives and usually do not contain any ethanol (some places even advertise their premium fuel as having no ethanol at all).

Where can I get 93 octane?

A representative for Cumberland Farms, with gas stations in Connecticut, Florida, Maine, Massachusetts, New York, New Hampshire, Rhode Island, and Vermont, has reached out and said “All of our sites sell premium grade 93 octane except for the state of Maine. In Maine it is 91 octane.”

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.

Does higher octane gas have more ethanol?

The introduction of ethanol in fuels further complicates the octane debate. Ethanol has a higher octane rating than hydrocarbons and also ignites at much higher temperatures. Blending ethanol into pump gas will slow the combustion process and reduce the likelihood of engine knock.
