Oil Change Service in Superior, Wisconsin
Motor oil is sometimes referred to as “the lifeblood of your engine,” and that’s not too far from the truth.
Motor oil is the film of lubrication that enables moving parts to operate with each other at extremely close tolerances. Without it, parts like pistons and bearings would soon overheat to a point where they would actually fuse to each other and seize the engine. By cutting friction between parts, oil helps dissipate heat and reduce wear.
The normal combustion process, however, generates a tremendous amount of heat as well as byproducts like carbon and acids. Inevitably, these contaminants make their way into motor oil. Oil contains detergents and dispersants that suspend these particulates so they can circulate and be trapped by the oil filter…until the filter’s paper pleats become saturated and it can’t absorb any more. At that point, sludgy deposits of carbon will start to accumulate on important engine assemblies, cutting engine life.
Conventional motor oil was the standard for many years, and modern formulations of conventional oil have additives that can enable it to go 5,000 miles between oil changes. While synthetic/conventional blends are on the market for high-mileage vehicles, manufacturers now recommend full-synthetic for all new engines.
Synthetic oil has many advantages over conventional mineral-based oil:
- Synthetic oil is more stable and consistent at the molecular level
- Synthetic oil won’t thin out in hot weather or thicken in winter. Its improved flow properties mean better protection for the engine’s upper assemblies when you start up.
- While more expensive per quart, the extra cost of synthetic oil is offset by the fact that it can easily go 10-12,000 miles between oil changes (always consult owner’s manual for manufacturer’s recommended oil change interval)
