Why Should I Change My Oil? At the heart of every vehicle is the engine. Hundreds of moving parts have to work together under extreme conditions. Following your manufacturer's recommendations by changing your oil regularly can keep your car running for a long time. Friction creates tremendous heat -dirty, contaminated oil is unable to protect your engine against friction and heat. Clean, Fresh motor oil keeps the moving parts of your engine lubricated and reduces life robing heat. New motor oil contains special additives to provide necessary protection and increase efficiency -increasing fuel economy. Normal, everyday driving begins to break down the oil increasing the difficulty for the oil to protect against heat. Over time, contaminates accumulate in the oil decreasing its ability to cool, protect and clean the engine. This brings us back to the vehicle manufacturer's recommended oil change service interval. Most vehicles today come equipped with oil life monitors regulating the oil change interval for you -taking the guess work out of it. By following your vehicle manufacturer's recommended oil change interval and changing the oil and oil filter regularly, you can keep your engine working efficiently and avoid costly repairs in the future.

How often should I change my oil? Many automobile manufacturers started recommending Oil Change Intervals of 5,000 to 7,500 Miles on passenger cars and light trucks. For turbo charged engines, including light diesels, the recommendation usually remains around 5,000 to 7,000 miles. If you read the fine print in the owner's manual, you discover that recommendations for extended oil drain intervals of 5,000 to 7,500 miles are for vehicles driven under ideal circumstances. What most of us think of as "normal" driving is better represented by "severe service." This includes dusty conditions, sustained highway speeds during hot weather, and stop-and-go driving in traffic. For this category of driving pattern, which is better represented by "severe service" -the recommendation by the vehicle manufacturer is usually to change the oil every 4,000 to 6,000 miles or six months. A new engine with little or no wear can usually get by on a 7,500 mile oil change. But as an engine accumulates miles, blow-by increases. This allows more unburned fuel to enter the crankcase, diluting the engine oil, reducing its effectiveness and causing the engine oil to breakdown even sooner. So if the oil isn't changed often enough, you can accelerate wear and expect additional engine problems to come along with it. Such as an increase in emissions and oil consumption as well as a loss in performance and fuel economy. Newer engines are very demanding on the engine oil. Due to the increase in emission standards, car makers have had to increase combustion chamber temperatures, run leaner fuel systems, adjust ignition timing, narrow cooling system water jackets, and tighten engine oil tolerances. All this puts added demands on the engine oil lubricating system. Petroleum companies have really stepped up to the challenge and produce a product that not only provides better protection for today's engines, but also makes it possible to go past the old standard of 3,000 miles between oil changes. It has been our experience that MOST vehicles can safely go 4,000 to 6,000 miles between oil changes. However, we must always recommend following the manufacturers recommendation when it comes to something as important as routine oil changes. It is our hope that this information can help you make an informed, balanced decision. At Valley Mobile Oil we never pressure our customers to increase their frequency in oil changes unless we feel it is absolutely necessary.

How Often Should I Change the Oil if I Have an Oil Life Monitor System? About twenty years ago, GM introduced its modern Oil Life Monitor System (OLM). And since then, many manufacturers have followed suit. The Oil Life Monitor system monitors driving patterns, the temperature in the crankcase, moisture and numerous chamber events. Contrary to popular understanding, the Oil Life Monitor System does not use a sensor to test the quality of the oil or test the life remaining. It does however, use a sophisticated algorithm to calculate the life expectancy of the oil based on accumulated information from its various sensors. Over the years, most manufacturers have been very successful at calculating the serviceable life of the engine oil using the Oil Life Monitor System. Independent testing has proven the system to be accurate to within 10%. It has been our experience that with this Enhanced Schedule, motorists can confidently follow the recommendation of their Oil Life Monitor System.
