Buick and Chevrolet Oil Change: Protecting Your InvestmentAs you drive your car, moisture and exhaust pollutants contaminate your engine oil, reducing its ability to effectively protect vital engine components. The longer engine oil stays in service after the recommended maintenance schedule, the less its ability to lubricate and cool engine parts. Having your oil changed by a qualified GM technician at the recommended intervals, with a genuine GM oil filter, not only extends the life of your engine, but helps your vehicle retain a higher resale value. This is just one example of why scheduling an appointment to perform scheduled maintenance such as oil change, tire rotation, tune-ups and alignments are important to the health of your Buick or Chevrolet.
Engine Oil - The Lifeblood of your Buick ChevroletMost people know that engine oil provides protection against friction by creating a thin barrier of oil between the moving parts. But engine oil does more than reduce friction and prevent wear and damage. Did you know that oil also helps keep your engine clean? Dust and dirt that may have slipped by the air filter, along with contaminants produced during the combustion process are captured and retained by the engine oil. The oil filter removes the larger particles as the oil passes through it, but the oil still retains and continues to collect contaminants during its useful life. This is why engine oil is light in color when it goes in and very dark in color when it is removed and replaced. Since engine oil has a limited capacity to hold these contaminants, by not changing the oil on your Buick or Chevrolet at the scheduled intervals, those un-trapped contaminants could cause premature wear to engine components, or settle in the engine and oil pan in what is commonly referred to as sludge.
In addition to lubricating and helping to remove dirt, engine oil also helps the engine run cool. As oil circulates through the engine it rises in temperature, and carries that heat to the oil pan (which is exposed to a constant air flow when your vehicle is moving which helps dissipate the heat away from the engine. Some heavy duty vehicles may use an oil cooler, mounted behind the front grill near the radiator to further help reduce the heat transferred by engine oil.
