Does Premium Gas Last Longer?

No, it doesn't. The consumption rate doesn't depend on whether it is premium or regular. The octane level in regular fuel is 87, but premium fuel has 89, 91, and 93.

The advantage of using fuel with the 87 octane level and above is that it lowers the chances of your engine knocking. Some types of engines will show their full potential with the help of premium fuel only.

Why Do Turbo Engines Require Premium Gas?

Turbo engines are manufactured with high compression ratios or turbochargers. For optimal performance and fuel efficiency, turbo engines require fuel with higher octane levels. Gas with lower octane levels reduces the engine performance and may cause it to knock.

Therefore, manufacturers have optimized most vehicles to run on regular and premium fuel. It has enticed consumers to purchase luxury models of many car brands. And, if you are truly curious, you can read more about how these supercharged systems work -whether you have a luxury car or not!

Are Turbos Expensive To Maintain?

The type of maintenance will affect the maintenance cost. Turbos are relatively easier to maintain than regular engines. The only catch in turbo engines, they require frequent oil changes. It's not the case with regular engines.

Other items that don't survive long in turbos are spark plugs. Vehicles with turbo engines could change spark plugs every three years, while regular engine cars change them in seven years.

Here is a video on how to efficiently maintain your turbocharged car.

What Happens When You Accidently Put Regular Gas In A Premium Car?

Most luxury cars only require premium gas. Some consumers might put regular gas by accident. The lower octane gas might cause the engine to make a pinging noise. The noise means that the pistons in the engine are damaged. 

The warranty of your vehicle becomes void when the engine is damaged due to the consumer's negligence. The void warranty means that the damage won't be covered by the manufacturer.

Why Octane Levels Matter To Your Car

A gasoline vehicle ignites when the levels of air and fuel are optimal. The air and fuel mixture is compressed prior to each combustion.

The compression creates a lot of heat which the fuel should be able to withstand. If the fuel does not have the ideal octane level, it might ignite prematurely.

Therefore, manufacturers indicate the octane level in the fuel that is heat resistant for the said engine. It stops the engine from making a knocking sound. Supercharged engines need high octane levels due to their high compression levels.

Why Is Ethanol Added To Gasoline

Most of the gasoline sold is infused with ethanol. Ethanol has a higher octane rating than gasoline. It emits less carbon dioxide than petrol when burnt.

Subsequently, ethanol-infused petrol has less harmful emissions. This makes it a cleaner renewable fuel. Almost all fuel in the US has 10% ethanol.

To Sum Up

Some luxury cars can use regular gas without compromising their performance. Use fuel with the recommended octane levels to avoid damaging the engine.

Other vehicle models, especially those with turbo engines, can only use premium fuel. To save money and the car's warranty, read the car's manual or inquire from the dealers whether the car can use premium and regular gas.
