RECOMMENDED SERVICE INTERVALS
Protect your engine. Protect your investment. Stay ahead of costly repairs.
Regular oil changes are one of the most important services you can perform to help maintain engine lubrication, reduce internal wear, control contaminants, and extend engine life.
GASOLINE ENGINES
CHANGE ENGINE OIL EVERY:
3,000 MILES
OR
100 ENGINE HOURS
WHICHEVER COMES FIRST
Vehicles that idle frequently, make short trips, operate in extreme temperatures, tow, haul, or work under heavy loads can accumulate engine hours much faster than mileage.
DIESEL ENGINES
CHANGE ENGINE OIL EVERY:
5,000 MILES
OR
150 ENGINE HOURS
WHICHEVER COMES FIRST
Diesel engines used for towing, hauling, extended idling, job-site work, or other severe-duty applications can put significant operating time on the engine without accumulating large amounts of mileage.
DON'T RELY ON MILEAGE ALONE
Engine hours matter.
A vehicle can spend hundreds of hours running while barely moving. Extended idling still circulates and heats the engine oil and contributes to oil contamination and degradation.
Following both mileage and engine-hour intervals helps ensure your engine receives regular maintenance based on how much it actually operates.
