With oil life indicators pushing the average oil change past the 6,000-mile mark, it is not just the quality of the oil that’s improved, it is the quality of the filter, as well. Neglected oil change intervals can ruin the best engine oils and filters. As engine oil and the filter accumulate miles, they become contaminated with carbon, water and various acids, all of which are a byproduct of internal combustion that will form a film of black, gooey sludge on the interior parts of the engine.
With today’s vehicles, different makes and models have stark differences in component design and engineering. Likewise, the driving style between any two drivers on the road can be just as varied as the vehicles they own. So, the question then in the face of these variables is, “Why are most oil change guidelines still so uniform and generic?”
