As the oil moves through the various engine components it lubricates and cleans the deposits caused by an internal combustion.  These deposits cause the oil to turn dark.  Oil has detergents and additives that break down over time that is why we change oil.  Infrequent oil changes accelerate wear on the bearings, lifters and rings and other internal parts.  A good analogy would be washing clothes.  If your clothes are dirty and you don’t add enough detergent to the wash then your clothes don’t come out clean, and are likely to have residual stains if not laundered properly.

Your vehicle’s engine is the most expensive part of the whole car, so taking care of it is fundamental. And the most important part of preserving the engine is changing oil, which must be performed on schedule, using high-quality oil of the proper viscosity. That part is easy. The more complicated part is determining what constitutes “on schedule,” and selecting the right oil. Many manufacturers have recommended oil changes every 3000-5000 miles for many years.  With recent model years, some new vehicle manufacturers are recommending oil change intervals only every 5,000, 7,500, or even every 10,000 miles, for their newest models.

Fortunately, motor oil manufacturers have responded to this trend by offering “High Endurance” motor oils.  So, if you’re going to stick to the new longer schedules that your manufacturer might recommend for your new car, make sure your oil is up to the task by selecting a motor oil that fits the manufacturer’s recommendations as well as your personal driving habits. Skipping those simple, inexpensive oil changes can lead to very costly auto repairs as old oil produces a thick sludge that builds up on the inside of your engine, preventing all the moving parts from working properly, reducing fuel economy and shortening the lifespan of your engine, especially in the Texas heat.
