Engine oil not only loses its lubrication quality, or viscosity, over time, but it also collects acids and other byproducts of combustion, such as water. These substances are the enemies of bearings, metal surfaces, seals, and gaskets.

Changing the oil and filter on a 3 month, or 3,000-mile, schedule is good insurance against the possible damage that can occur. If the facility that is performs the oil change inspects the vehicle properly, you will save money by identifying a need before it becomes an emergency. It is always wise to make sure a certified technician is handling your vehicle.

Under normal driving conditions, it is best to have the differential and transfer case fluids replaced at the intervals recommended by the manufacturer. Under more severe conditions, it may be advisable to have the fluids changed more often. The fluids in these units may become contaminated over time, and can lose their lubrication qualities during normal use.

Transmission fluid breaks down over time due to the extreme temperatures experienced during operation. Under normal driving conditions, it is best to have the transmission fluid flushed at the intervals recommended by the manufacturer. However, under severe driving conditions, it may be advisable to have it flushed more often. The idea is to replace the fluid before it looks dark or smells burned so the transmission can operate at its best. This will prolong the life of the transmission and prevent costly repairs and inconvenience for you.

Rotating your tires every 5,000 miles (based on tire application) helps ensure the life of the tire and its warranty. If you don’t rotate your tires, you may experience tire damage (cupping), which may affect the steering of your vehicle. You should pay close attention to the tread depth of your tires to make sure that the wear patterns are equal.

It is typical that they not need replacement for at least 60,000 miles under normal driving conditions. Replacing worn belts reduces the chance of breakdowns, the chance of damaging other components when they break and insures that all belt-driven components operate normally. Replacing worn hoses reduces the chance of failure that could cause engine overheating, and allows for testing of the coolant.
