A 4500/5500 cab/chassis truck used for commercial purposes is often a very heavily used and abused truck. It's service intervals would fall under the 'severe' category. If the owner's manual says change it at 7500 miles, that's what I would do.


The manual says 60,000/120,000 miles depending on duty cycles.
