How Often Should I Change My Truck's Oil?
Oil change intervals for diesel trucks vary, but it’s typically recommended every 5,000 to 7,500 miles, depending on usage and driving conditions. Regular oil changes are crucial as they prevent contaminants from building up in the engine, helping to reduce wear and extend the engine’s life.
What Happens If You Don’t Change The Oil In Your Truck?
Failing to change the oil can lead to a buildup of sludge and contaminants, which reduces its ability to lubricate the engine. This lack of lubrication can cause engine components to overheat and wear down more quickly, eventually leading to significant, costly damage. Consistent oil changes are essential to keep your engine in good health and avoid unexpected repairs.
