What kind of engine oil do you put in a Ford 1997 Explorer XLT?

The recommended engine oil for a 1997 Ford Explorer XLT depends on the engine it has. There were several engine options available that year. To be certain, you must check your owner's manual. It will specify the correct viscosity (like 5W-30 or 10W-30) and the API certification (like SL or SJ).

Without knowing the engine size, I can only give general advice: Most likely, your 1997 Explorer XLT would use a conventional oil with a viscosity rating of 5W-30 or 10W-30, meeting at least an API certification of SJ (older vehicles may need an older standard). However, this is not a guarantee and you should consult your owner's manual. Using the incorrect oil can seriously damage your engine.
