Premium Fuel vs. Regular
While any Chicago Ferrari driver should know not to pump regular gasoline into the tank of a Portofino or GTC4Lusso — those hand-assembled engines require proper care — the reasoning behind it may seem a little counterintuitive.
What’s the Difference?
The idea that premium fuel costs more because it’s better than regular is not quite wrong, but it’s not quite right, either.
- Regular gasoline actually combusts easier than premium.
- A lower octane rating indicates that a fuel is more likely to combust through compression alone (called pre-ignition).
- Higher octane fuels are less likely to pre-ignite.
If all that mattered was starting the combustion reaction and producing energy, pre-ignition wouldn’t be much of an issue. In fact, the typical family sedan is able to use low-octane fuels specifically because technology has been developed to mitigate pre-ignition — at the cost of performance capabilities. Precision automobiles require precision in every aspect, however, and there is not a way to build a Ferrari that is truly a Ferrari if it is designed to run on unpredictable fuels.
If pre-ignition doesn’t sound familiar to you, you may have heard it by its other name: knocking.
What is Knocking, and Why is it a Problem?
Once a problem the everyday driver needed to be aware of, more and more vehicles have been engineered to mitigate the risk of pre-ignition, and young drivers may have never needed to worry about it. While “pre-ignition” describes what’s happening, “knocking” describes how a driver can tell that their vehicle is having pre-ignition issues — unpredictable combustion sounds like knocking coming from under the hood.
It might sound like this is just a mild inconvenience, but each pre-ignition is an explosion in the engine that can send shockwaves through the most expensive part of a vehicle, risking significant damage. This is why a driver should always use the fuel recommended in their owner’s manual.
Ethanol vs. Non-Ethanol Gas
Octane rating is just one part of the math behind your fuel. Few fueling stations use pure gasoline anymore, with many featuring fuel that is 10% (or more) ethanol. Much like the lower octane rating fuel, gasoline with ethanol in it might be fine for a family sedan, but it is not recommended for a Ferrari. Save yourself some time and find a non-ethanol gas station near you instead of pulling up to the pump and hoping.
