When it comes to most passenger cars, spending extra money on high-octane gas is a waste of money. Higher octane levels only benefit high performance vehicles which require a certain type of fuel and unless your car’s owner’s manual specifically calls for a higher octane gasoline, there’s no need to purchase it.
However, this doesn’t mean that the quality of gasoline doesn’t matter. When you go to fill up your car, it’s important that you go to a reputable gas station that is known for having high quality gasoline. Unfiltered gasoline can add sediments and other particles to your gasoline which can hurt your car’s performance or even cause damage.
If you’re unsure, ask the gas station attendant if their gasoline is filtered at the pump and how frequently the pump filter is changed. If you aren’t happy with the answer you receive, it’s a good idea to move onto another station.
