Routine scheduled maintenance isn’t like it used to be; it used to be pretty simple!
Every 3,000 miles you changed your oil, checked all other fluid levels and lubed the chassis. As oils and technology improved, oil changes were extended out to 5,000 miles.
These days it is a whole different ballgame. Original Equipment Manufacturers (OEMs) are pretty specific about what and when items require servicing. Factors like engine operating conditions, idle time, temperature and mileage are now taken into account. Many trucks now use oil life indicators to gauge percentage of remaining oil life based on inputs from the Electronic Control Module (ECM).
Engine oil viscosity charts provide OEM recommendations for oil usage based on temperature operating conditions for both single and multi-grade oils. This helps ensure correct viscosity is used as well as maintaining any OEM warranty requirements. Using the wrong viscosity oil or incorrect fluid application may cause severe engine or component damage.
