While you *can* use higher octane fuels, it's not necessary and won't provide any real benefit for your engine. Using premium gas in a vehicle designed for regular is simply a waste of money.
Here's why:
* Engine Design: The 5.0L engine in your Explorer is designed to operate efficiently on regular unleaded. It's not equipped with knock sensors or other technology that would take advantage of higher octane fuels.
* Performance and Fuel Economy: Using premium gas in a regular-gas engine won't improve performance or fuel economy.
* Cost: Premium gas is more expensive, so using it unnecessarily will cost you more at the pump.
Always refer to your owner's manual for specific fuel recommendations for your vehicle. It's the most reliable source of information for your 1997 Ford Explorer.
