What does OEM maintenance schedule mean?

OEM stands for Original Equipment Manufacturer. The OEM maintenance schedule is the service plan the company that built your car specifies for it — the intervals, fluids, and parts validated against that specific engine and drivetrain during development and durability testing.

Should I follow the normal or severe maintenance schedule?

Read the severe-conditions definition in your manual before assuming normal applies. Short trips under about 10 miles, extended idling, towing, dusty roads, and extreme heat or cold all qualify. Frequent short trips are the most commonly overlooked trigger — a commute that never fully warms the engine is severe service, not light duty.

Does following the manufacturer schedule void or protect my warranty?

Following it protects you. Warranty claims can be denied when required maintenance wasn't performed, and the burden of proof is on the owner. You do not have to use the dealer — independent shops are fine in most markets — but you do need records showing the work was done on time.

Is the manufacturer schedule always better than what my shop recommends?

For intervals and fluid specifications, start with the manufacturer — those were validated on your exact powertrain. A good mechanic adds value by inspecting your specific car and flagging real wear. Treat their findings as evidence and the OEM schedule as the baseline.

What happens if I skip a service interval?

Usually nothing immediately, which is what makes it tempting. The cost shows up later — degraded oil accelerates bearing and timing-component wear, old brake fluid absorbs moisture and reduces braking performance, and a stretched timing belt can fail catastrophically on an interference engine. Deferred maintenance tends to convert into a repair an order of magnitude more expensive.
