"While Ford's EcoBoost F-150 stands out as an obvious exception, the Dodge Charger's numbers make for a tidy summary of our findings. If you buy fuel with an octane rating above the manufacturer's requirement, you're likely to feel it in your wallet more than the seat of your pants."
What Causes Your Engine To Knock?
Detonation knock is a noise you'll hear when the air-fuel mixture in the cylinders doesn't ignite properly. When this happens, it causes a pounding or rattling noise. The cause of this can be from using lower octane fuel than what is recommended for your engine, incorrect timing, or too much compression.
What Do Octane Ratings Mean?
The octane rating is a measure of how heat resistant a fuel is. This is so the fuel does not knock or ping when it is combusted. In other words, high-octane fuels are more resistant to pre-ignition and detonation.
In the past cars without modern fuel injection systems needed higher octane fuel to prevent knocking but with today's technology, most cars can run on the lower 87 octane gas without any problem.
Is There A Difference Between 87 & 93 Octane Gas?
The actual fuel is the same but the refining process for higher octane fuel is more expensive. So, if you're looking to save a few bucks at the pump, 87 octane gas is the way to go. Just be sure to check with your car's manufacturer first to see if it is okay to use.
