We’re all aware that automotive manufacturers have recommended service intervals. Following recommended service intervals is very important. The engineers that design our vehicles have tested the various systems and components to meet durability and safety standards. Some of these standards are self-imposed and others, like those for emissions components, are government mandated.
The maintenance schedules are designed to achieve the standards. Think of the benefits of following recommended intervals as falling into three general categories: Protection, Efficiency and Safety.
Protection. Let’s start with motor oil. First of all, the engineers recommend a particular weight and type of motor oil. All of their oil change recommendations assume using the proper motor oil. Motor oil contains detergents and other additives that clean the engine and provide corrosion resistance. Over time, the additives are depleted. The oil also becomes contaminated by water, dirt and combustion gases.
Extending your interval beyond the recommendation means that your engine will be operating without the full protection of fresh motor oil. It also means that sludge can form in contaminated oil and clog up passages in the engine, starving parts from needed lubrication.
Efficiency. Some services are designed to keep automotive systems operating efficiently. For example, the fuel system gets clogged up with gum and varnish from the fuel. Fuel doesn’t flow efficiently which reduces fuel economy. A fuel system cleaning restores the fuel system’s efficiency and increases your gas mileage.
Safety. Your brakes are obviously one of the most important safety systems on your vehicle. The manufacturer has scheduled brake pad replacement as well as power brake fluid drain and replacement intervals. Because brakes are so important, a brake inspection is also on the schedule to head off problems before they result in an accident.
Check your owner’s manual for recommended service schedules or talk with your auto service adviser.
You may be surprised to learn that various inspections may be on your list of factory recommendations. These inspections are usually at major intervals like fifteen or thirty thousand miles. They’re designed to uncover important parts that may be close to failing. Your owner’s manual can tell you when to change your oil, but it can’t tell you that you have a radiator hose that’s bulging and about to burst. For that you need a trained technician. These scheduled inspections are in addition to the multi-point inspections done with a full-service oil change.
