I've put regular in mine since I bought it in July 2005 with no problems. They recommend premium to get the rated max horsepower. Meaning if you want 265 hp then you have to use premium. I tried premium once and there was no difference that I could see. Use the cheap stuff.

White 05 LE crew cab 4x4. Mods so far- Rollbak bed cover, custom Yakima bike rack, Pathfinder center console, Pathfinder window trim, steering wheel audio controls added, vent visors and window tint.

This is a hotly debated topic. The 4.0 L can take regular or premium gasoline. The higher octane fuel can lead to better mileage and power if you keep using premium. This is to allow the ECU to train the spark advance to take advantage of the more knock resistant fuel. This training period make take some time.

The problem seems to stem from conclusions drawn from short basis tests. Meaning, some will do one tank and claim Great! or Lousy! You must have a larger footprint to fully assess the value of premium fuel.

As for me; I use premium and found that it increases mileage in excess of its incremental per gallon cost. There is also more power emanating from the engine. But I don't stomp on it all that often so it's the mileage benefit that keeps me on premium.

Go premium

If you take a second and look at the benefits of using premium over regular you may want to fork out an extra what 8 cents per gallon. Figure with a 18 gallon tank you would spend about an extra $15, but you would be getting an increase of about 4 mpg. Plus by using better gas you engine would have less wear and tear in the long run. I know this works for me and I drive my truck an average of 75 miles a day, stop and go making service calls.
