Premium Fuel: Friend Or Foe For Your Car's Performance?

Accidentally putting premium gas in a car designed to run on regular fuel will not harm the car’s parts and components. However, note that there have been technical service bulletins from Ford and Chrysler warning against frequently using higher octane fuels in vehicles that are built to use 87 octane fuel, because premium fuel burns slower and tends to leave unburned fuel deposits on the piston crown and cylinder head that will eventually turn into carbon.

Premium fuel burns slower and tends to leave unburned fuel deposits on the piston crown and cylinder head

Ford and Chrysler warn customers against frequently using higher octane fuels in vehicles that are built to use 87 octane fuel because premium fuel burns slower and tends to leave unburned fuel deposits on the piston crown and cylinder head. Regular gas has an 87 octane rating, which is the lowest octane number. Meanwhile, premium gasoline has the highest octane rating, usually ranging between 91 and 94.

Accidentally putting premium gas just once or twice in a car designed to run on regular fuel will not harm its parts and components. However, frequent use of premium fuel in a car that is built to use 87 octane fuel can cause unburned fuel deposits on the piston crown and cylinder head that will eventually turn into carbon. This carbon, when it becomes heavy enough to increase compression, can cause detonation.

Most people believe premium fuel burns faster but it actually burns slower than regular fuel. Thus, low octane fuel is more susceptible to spontaneous combustion than high octane fuel. When carbon begins to accumulate in the combustion chamber for other reasons (like oil consumption) leading to detonation or spark knock, using premium fuel reduces the knocking until the premium fuel begins to add more carbon to what’s already there.

Ford and Chrysler warn customers against frequent use of premium fuel

Ford and Chrysler have issued warnings to customers about the frequent use of premium fuel in vehicles designed to run on regular fuel. Premium fuel burns slower and tends to leave unburned fuel deposits on the piston crown and cylinder head that will eventually turn into carbon. This can damage the engine and cause performance issues.

Regularly using premium fuel in a vehicle designed to run on regular fuel can damage the engine and cause performance issues. Therefore, it is important to check the fuel type before filling up the tank.

In conclusion, Ford and Chrysler have issued warnings to customers about the frequent use of premium fuel in vehicles designed to run on regular fuel. Premium fuel burns slower and tends to leave unburned fuel deposits on the piston crown and cylinder head that will eventually turn into carbon. This can damage the engine and cause performance issues.

You’ve accidentally put premium-grade gasoline in the fuel tank. So what happens if you put premium gas in a regular gas car? Will running on high-performance fuel cause issues with performance or inflict damage on critical parts of the fuel system and engine? No. Accidentally putting premium gas in a car designed to run on regular fuel will not harm the car’s parts and components.

You drive a car designed to run on regular gasoline. On the way to your latest destination, you notice the reading in the fuel gauge that warns the gas tank is low. Since you don’t want the risk of running on fumes, you pull into the first gas station you come across. As you finish filling the tank, you look at the gas pump and realize it’s not the one for regular fuel. You’ve accidentally put premium-grade gasoline in the fuel tank. So what happens if you put premium gas in a regular gas car? Will running on high-performance fuel cause issues with performance or inflict damage on critical parts of the fuel system and engine? No.

Regular gas has an 87 octane rating, while premium gasoline has a higher octane rating

Regular gas has an 87 octane rating, which is the lowest octane number and is suitable for most engines. Premium gasoline has a higher octane rating of 91-94, and is required or recommended for engines that use a higher compression ratio and/or supercharging or turbocharging to force more air into the engine.

Accidentally putting premium gas in a car designed to run on regular fuel will not harm the car’s parts and components. However, Ford and Chrysler warn customers against frequently using higher octane fuels in vehicles that are built to use 87 octane fuel because premium fuel burns slower and tends to leave unburned fuel deposits on the piston crown and cylinder head that will eventually turn into carbon.

Most gasoline vehicles are designed to run on 87 octane, but others are designed to use higher octane fuel. Using unleaded gas with octane levels lower than what the carmaker recommends can reduce performance and may cause damage over time. Always follow your owner’s manual guidance when choosing a type of gas. Selecting a grade of gasoline simply because it has a higher octane rating might not be the best choice for your car or your budget.

Premium fuel can turn into carbon and inflict damage on the fuel system and engine

Premium fuel burns slower and tends to leave unburned fuel deposits on the piston crown and cylinder head that will eventually turn into carbon. Carbon build-up restricts the engine’s ability to breathe and maintain this ratio. Misfires have the potential to cause permanent damage to your engine, and they may also cause the vehicle computer to log a trouble code and illuminate the check engine light. Powering your vehicle with low-quality fuel leads to poor, incomplete combustion, and it will also cause greater amounts of carbon to gather and clump inside the engine. Sometimes, higher octane fuels can cause an engine designed for lower octane fuel to stumble when first started cold.
