Oil Changes in Bethlehem, Emmaus, Quakertown PA


Your vehicle relies on clean motor oil to be able to run. The moving parts in the engine all operate on extremely tight tolerances with each other – no more than a few microns – and need a film of lubrication to reduce friction and wear. Without motor oil, the engine would quickly overheat to a point where the steel parts actually weld to each other and seize the engine.

Along with the heat of friction, the internal combustion engine generates a great deal of heat from the combustion process itself – thousands of tiny explosions that provide power to move a vehicle down the road. Along with heat, these explosions generate carbon , water vapor and acids which make their way into the oil. These contaminants, along with microscopic metal shavings from metal parts, start to contaminate motor oil over the course of a few thousand miles.

Oil contains detergents and dispersants which suspend particles in the oil so they can be trapped by the oil filter’s paper pleats. In time, though, the filter becomes saturated and can’t absorb any more. That’s when crusty carbon deposits or buildups of sludge start to accumulate on bearings and other assemblies, increasing wear and shortening engine life.

Conventional motor oil used to have a 3,000 mile oil change interval. Today’s motor oil formulations have improved to a point where a 5,000 mile interval is fine…but synthetic motor oil outperforms conventional oil in just about every respect. That’s why synthetic oil is the manufacturer’s recommendation for all new vehicles. While synthetic is considerably more expensive, that extra cost is offset somewhat by a 10-12,000 mile oil change interval and improved engine protection.

Can’t remember when your last oil change was? Just pull your oil dipstick and have a look. Fresh, clean motor oil should be honey-colored and translucent. Oil that’s darker but still translucent is okay for awhile, but oil that’s the color of black coffee and has an acrid smell should be changed right away.
