What happens if I put 89 instead of 91?

If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you'll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.

Does 89 give better gas mileage?

Regular gas typically has an 87-octane rating, and the 88-90 range is considered midgrade. While premium gas drives performance in certain engines, the idea that it's more fuel efficient is a myth. Any fuel efficiency gained would stem from engine performance and not the gas itself.

Does 89 gas clean your engine?

Will higher octane gasoline clean your engine better? No. High octane gasoline doesn't outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car's engine. This is a myth.

Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.

Is 89 good for Mercedes-Benz?

Its engine uses higher pre-ignition temperatures designed for a higher-octane fuel. Therefore, the best gasoline for Mercedes Benz engines we recommend is premium unleaded gasoline. As also recommended by its manufacturer, Mercedes-Benz engines particularly require gasoline of 91 octanes or higher.

What gas can Mercedes take?

In order to properly maintain your ride and keep it running like new for years to come, our Mercedes-Benz dealer serving Washington, D.C. recommends filling up your Mercedes-Benz vehicle with premium unleaded gasoline that is 91 octane or higher.

Premium: 91 to 94 octane rating.

Why do people use 89 gas?

So, gas stations started offering a mid-grade option, hoping it would attract thriftier drivers and anyone who wanted better-than-average knock resistance but at a more reasonable price than premium. Some even believed this new grade would usurp regular unleaded in time.

Is 89 really better than 87?

Regular gas carries an octane level rating between 85 and 88, with an average rating of 87. Plus grade gas carries an 88 to 90 octane level rating, with an 89 average. Premium gas comes with a 90 plus octane rating that averages out to about 92. Fuels of different grades will not burn the same way.

Is it bad to put 89 gas instead of 87?

If you opt for a higher octane than your manual recommends—say, 89 instead of 87—your car will be perfectly fine. It will not, however, improve your car's mileage or give it any sort of extra performance boost. The only thing it will do is cost you extra money, so don't do this.

What happens if you put regular gas in a 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.

What if I accidentally put regular gas in my Mercedes?

Unless the vehicle (any vehicle) states that it Requires Premeum fuel, then regular 87 octane is 100% fine. If it “Requires” Premeum 91 or 93, then using a lower octane will lower mpg and performance!

Is it safe to start putting in 89 octane gas over 87 since a car can run on either? Yes, you can always run higher octane rating than recommended, although it will provide no benefit. You can also run lower octane rating, so long as are cautious and keep a light load on engine.

The owner's manual for most Mercedes-Benz models states that you should use only unleaded 91 octane gasoline when using them. The electronic computer system detects the fuel type in the car. This system ensures that the vehicle operates appropriately with this fuel type.

Does 89 gas make a difference?

For high performance, high compression sports car engines, 89 and 91 octanes give improved anti-knock or predetonation resistance that is important for these engines to run without performance loss and even engine damage due to pre-detonation under load (acceleration).

What happens if you put regular gas in premium car?

Gasoline with a high octane rating is more difficult to ignite, which helps prevent pre-ignition and knocking in high performance engines. If your car requires premium gas, you can damage the engine if you consistently fill up with regular.

Is there a big difference between 89 and 91 octane?

Raising the octane rating (also known as the anti-knock index) doesn't change the energy content of a gallon of gasoline. A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.

Is 91 better than 89?

Using 91 octane will probably allow your engine to operate at full efficiency, giving you slightly better fuel economy and power.

Can any car use 89?
