This seemingly simple question has become a very complicated, contentious topic as there are so many different opinions as to when you should change the oil in your car. Yet is also perhaps the most important topic because lack of maintenance is the leading cause for the need of auto repair service due to mechanical failure in Bedford PA. For years the automotive service community has agreed that changing your oil every three months or 3,000 miles was common practice however auto manufacturers and oil producers have insisted that the interval for changing your oil is much greater.
In order to properly answer this question we need to look at some of the reasons why these service intervals have been established and the advantages for each.
In 2003 auto manufacturers began to release documentation showing that their vehicles could extend the oil change service interval beyond 3,000 miles between oil changes. They attributed this increase to better engineering and use of newer materials that decreased friction within their engines. While this sounded good on paper, very few actual tests performed by independent agencies could actually duplicate their claims. While it is true that modern engines use lighter weight materials and employee high-end lubricants such as synthetics; many independent studies still found that the engine operating temperature as well as friction ratios still remain constant in spite of their claims of improvement.
Auto manufacturers constantly compete with one another in a variety of areas from performance, comfort, styling, features and cost of ownership. Cost of ownership has become a hot button topic for many auto manufacturers as they attempt to show consumers that their vehicle is cheaper to maintain than their competitors. For example: a BMW’s cost of ownership would be higher than a Toyota, at a dealership level, because the parts and labor traditionally are higher for high-end vehicles. However, the purchase price of a Lexus and BMW are very similar, so in order to attract customers to purchase their vehicle Lexus, for example, would show the cost of ownership over a five-year period of time as being less expensive than owning a BMW. By increasing the oil change intervals from 3,000 miles to 5,000 miles that allows Lexus to show the cost of ownership to be less, at least on paper. BMW quickly followed suit by raising their intervals to 7,500 miles between oil changes. Manufacturers today commonly set their oil change intervals at 15,000 miles; yet cannot show any dramatic engineering changes in the oil delivery system or reduction of friction to compensate for the additional mileage.
One area that contributes to maintenance costs is lease vs. ownership. If you’re leasing a car and the manufacturer says the change the oil every 15,000 miles; who cares right? You’re going to turn the car in at 25,000 miles anyway so it doesn’t matter to you whether the engine is damaged because of lack of lubrication. Ownership however means that you will more than likely keep that car, in some cases, until the wheels fall off. In that case the wise choice would be to maintain the vehicle in such a way that would extend the life of the engine and lubricated components reducing the auto repairs in Bedford PA needed from engine wear and fatigue. It is for this reason that Town Hill Auto Repair Service in Bedford recommends to maintain a 3,000 to 5,000 mile oil change interval depending on the filter and oil used.
Friction and heat are the leading causes of engine wear and break down for cars causing premature auto repair needs; regardless of the engine, year or model. One area where the aftermarket industry has excelled is the creation of synthetic lubricants that significantly reduce friction within the motor. Valvoline is leading the industry with lubricants designed to work with traditional, conventional and modern engines to not only reduce wear but increase the useful life of an engine. Napa’s oil filters utilizing premium filter components significantly remove more contaminants from the engine than traditional oil filters and in many cases original manufacture oil filters. This combination of better oil and better filters can certainly help protect your engine and increase the time needed between oil changes; However; despite the advantages of synthetic fluid and premium oil filters; a conventional engine still produces, by design, operating temperatures that continue to contribute to wear and metallic component break down. This must be considered especially on older, higher mileage engines.
At the end of the day Town Hill Auto Repair Service in Bedford recommends maintaining your car in a way that will extend the life of your engine and driveline components for many years to come. By using quality Valvoline oil and Premium Napa oil filters we can help increase the oil change interval. However; we do not endorse the mindset of 15,000 miles between oil changes. Much of our recommendations also stem from the vehicle themselves and the reputation of engineering that a particular engine or engine design has. Click here to learn more about us
