What happens if you put 87 instead of 93?

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 may feel a difference in the way the vehicle runs and may notice an improvement in gas mileage, but that’s about all that will happen.

What happens if you don’t put premium gas in a Mercedes?

The less octane in the gas, the faster it burns. Your Mercedes-Benz has a number of sensors in the engine designed to precisely time the firing of the cylinders. Low octane fuel will cause the pistons to fire too quickly, eventually causing serious and even catastrophic damage to the engine.

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

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 damage my engine with higher octane?

The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.

Does premium gas last longer than unleaded?

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.

What happens if I accidentally put regular gas in my Mercedes?

If you mistakenly fill up with regular fuel, your car’s ECU will adjust engine timing and performance to work with the lower-octane fuel. In most cases, this is ok for the times when there are no premium pumps around, but it’s not ideal to run the cheapest fuel possible for extended periods of time.

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.

What happens if you put regular in a Mercedes?

Regular gas can reduce the life of the engine, trigher malfuctions such as Check Engine Light and most importantly it can cause the fuel to pre-ignite, causing pre-detonation (engine knocking). Using lower rated gasoline on your Mercedes-Benz not only causes problems but also decrease the fuel efficiency.

Will higher octane gas hurt my car?

What happens if you use regular gas instead of premium?

Some manufacturers recommend premium gas but say that regular or mid-grade gas can be used instead. They usually warn that using lower-octane gas could reduce performance and fuel economy. When that happens noticeably, or if engine knock occurs, they advise to start using premium.

Can I switch from premium to regular gas?

Now, many cars can adjust the engine’s timing to prevent knock, thus allowing you to use lower octane gasoline if you so choose. If your car merely recommends premium gas, you can safely switch to a lower octane without risking engine damage.

What will happen if you put regular gas in a premium car?

Using regular gas in an engine that requires premium could void your warranty. That is most likely to happen if using regular causes severe engine knock or pinging (premature ignition of the fuel, also known as detonation) that damages the pistons or other engine parts.

Is it bad to put premium gas in a regular car?

Putting premium gas in a car that takes regular won’t harm it. However, putting regular gas in a car that takes premium can and, over time, will likely harm it. The only difference between gasoline grades is the additives put into the gasoline, otherwise it is gasoline.
