* Truck Make and Model: Manufacturers provide recommended oil change intervals in the owner's manual. This is the best starting point.
* Type of Oil: Synthetic oil generally lasts longer than conventional oil. Synthetic blends fall somewhere in between.
* Driving Conditions: Severe conditions like frequent idling, towing heavy loads, extreme temperatures, or dusty environments necessitate more frequent changes.
* Oil Analysis: Regular oil analysis can help determine the actual condition of the oil and extend or shorten the interval accordingly.
Generally, you can expect oil change intervals ranging from 10,000 to 25,000 miles (or even more with synthetic oil and favorable conditions). However, always consult your owner's manual for the manufacturer's specific recommendations. Ignoring these recommendations can lead to premature engine wear and costly repairs.
Many fleet operators and trucking companies use oil analysis to optimize oil change intervals, often stretching them beyond the manufacturer's suggested intervals in favorable conditions. But for the average owner, sticking to the manufacturer's recommendation is the safest approach.
