Here is a direct quote from your 98 owner's manual:
Octane recommendations
Your vehicle is designed to use regular unleaded with an (R+M)/2 octane rating of 87. We do not recommend gasolines labeled as “regular” in high altitude areas that are sold with octane ratings of 86 or even less.

If the 92 "seems" to last longer, then actually do the math. Calculate your mpg with each octane rating. Who knows, for some reason you may get better mileage with 92. But you need to factor in the additional cost of the 92 vs 87 and see if you're actually saving money with the 92.
Most people on this forum use 87 because that's what the manual calls for.
