Consider this, oil breaks down due to high temperatures inside your engine. When this happens the oil becomes less effective as a lubricant and without a good lubricant, parts of the engine rub together causing friction wearing on each other. The oil manufacturers also inject additives in the process that neutralize the acids. Over time (3,000 to 5,000 miles), these additives are severely depleted and are not as effective.
While the old standard “lube, oil and filter” is a great place to start, we at Extra Mile Auto Service of Coatesville are “driven to go the extra mile”. During our Three Thousand Mile Service oil change we inspect all aspects of your vehicle, from the lights to the exhaust system and let you know what we find with a written inspection for your records.
Your owner’s manual recommendations for oil and filter changes vary from 3,000 to 10,000 miles. However, we recommend that you change your oil and filter at least every 6,000 miles for synthetic oils, 4,000 miles for semi synthetic oils and 3,000 miles for natural oils. That’s our best estimate, It may be too late for some people and too soon for a few, but for the vast majority a 3,000 to 6,000-mile oil change will help your engine last for the life of your vehicle.
Clean oil performs better than dirty oil and is relatively inexpensive. Changing your oil every 3,000 to 6,000 miles is a reasonable insurance policy against potential major repairs down the road.
