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

What happens if you put 93 gas in an 87 car? In situations like this, it's always preferable to be safe than sorry. The result of mixing 87 and 93 gas is that not much happens. Regular, midgrade, and premium gas grades refer to the gasoline's octane content. Additionally, that is what those numbers 87 and 93 indicate. Premium gas is defined as having an octane level of 91 or higher. Midgrade gas has an octane level of 89 or higher, and normal gas falls between the two.

The performance of your engine will be marginally improved by using gas with a higher octane rating. Most of us drive a car daily that uses standard, unleaded fuel. When we fill up at the gas station, it becomes quite easy. But occasionally, someone can inadvertently use a different fuel type to fill up their car. What should you do in such a situation? 


Most modern cars and trucks are equipped with electronic fuel management systems that can detect a changeover in gasoline type and modify the ignition timing and fuel injection to compensate. This means they can distinguish between higher-octane gas (premium) and lower-octane gas (regular). Don't drive if you mistakenly put higher octane blend fuel (such as 91, 92, or 93) in your tank than what you regularly use, such as 87-octane gasoline.



If your engine runs fine regularly, using premium is unlikely to increase acceleration or fuel economy significantly. Despite what you may have heard, normal gas still contains the same detergent chemicals. Thus, using premium gas won't make your fuel injectors or other elements of the fuel system cleaner.


The primary distinction between standard and premium octane is the latter's higher octane rating, 91 or higher. Because it has a higher octane rating, premium gas is less likely to start burning before it should, which could cause damage and sometimes make the engine knock or ping. Greater octane fuel enables engines to run at higher compression ratios, with more sophisticated ignition timing, or with forced air induction using turbochargers or other devices.

Do 87 and 93 differ from one another?

Most states regularly rate gas at 87 octanes, whereas premium gas is sometimes rated higher at 91 or 93. Higher octane fuel can resist higher compression levels without detonating. In general, the chance that a detonation will occur at the incorrect moment decreases with increasing octane grade.


What Happens If You Fill Your Car With the Wrong Octane of Gas?

In the past, 87 octanes would cause the engine to begin banging before the car had left the gas station when used in a vehicle that required premium fuel, but things have changed. Your car's ECU will modify engine timing and performance if you accidentally fill up with ordinary petrol so that it will work with the lower-octane fuel. When there aren't any premium pumps nearby, this is usually acceptable, but using the cheapest fuel for prolonged periods is not recommended.

Conclusion;

Don't be alarmed if you typically fill your tank with 87-octane fuel but mistakenly put in a higher octane blend (such as 91, 92, or 93). The gas you're using to fill your car or truck will burn differently in your engine because it's a different blend.


Now you know what happens if you put 93 gas in an 87 car.

Although tempting the gods of auto repair is never a smart idea, there are occasions when premium fuel pumps are not available when you need them. If you've ever been in a scenario like this, you know how frustrating it can be to try to figure out what the effects will be on your car. The good news is that nothing bad will typically occur.
