You’ve probably seen different octane levels in your choices for gasoline - your gas station probably brands them as “regular,” “plus,” and “premium.” The difference in these is the octane rating, which describes the fuel’s ability to be compressed without detonating.
A fuel type with a higher octane level can be compressed further without detonating. What this means for your car, is that the fuel is much more resistance to engine knocking. That is to say, there is less propensity for the fuel to knock inside the engine. But what does that mean for your car?
The scoop with high octane fuel
Some cars need high-octane gasoline to function. Specifically, this is the case in high-performance cars, who require a higher octane number to function, as their engine more vigorously compresses the gasoline. However, if your car doesn’t expressly need higher octane fuel, there are limited benefits to using it over regular unleaded gasoline.
There may be benefits in fuel economy associated with higher octane fuel. Higher octane fuel results in more efficient combustion within your engine chamber, which can lead to some mileage gains. However, this does not justify the increased price on premium fuel, which can cost you over $100 a year more if you fill up regularly.
The FTC, in fact, states that there are no advantages to using high octane fuel over regular unleaded gasoline unless your engine expressly requires its use.
In fact, for most cars, lower octane fuel poses no problem, as your car’s ignition system monitors engine knocking and reduced compression to avoid the problem.
In the end, your car’s fuel choice is just that - a choice. But unless your car expressly requires high-octane fuel, there are little to no benefits associated with its use.
