Oil Sludge Build-Up In My Car's Engine

imageWe often hear reports in the news or internet about the "3000 mile oil change myth" or about how businesses who are trying to sell premature oil services. An oil change prevents engine oil sludge build up. The first sign of oil sludge often appears under the engine oil cap - see photo.

Some say that there's not really any difference between engine oil brands, types (such as synthetic vs. conventional) or even where you have your oil change performed. 

Is any of that true? -or- Does it really make a difference what oil you use?

TOP 10 ENGINE OIL FACTS

  1. Auto engines produce waste internally into the oil. (exhaust fumes, fuel vapor, heat, water moisture, etc.)
  2. Oil does not regenerate and depending on oil type, brand, quality and chemical composition. It's purpose is filtering and absorption agent for waste production caused by the engine's combustion and even moisture absorption when the vehicle is sitting unused. 
  3. A variety of oil filters, screens and valves in the car assist the oil in eliminating combustion by-products.
  4. When the oil begins to breakdown, it no longer can absorb waste products properly and the filters, screens and valves get overwhelmed. Conventional oil types will coagulate and block important oil passages. 
  5. Fluid and filter replacement is needed before coagulation forms to prevent bigger problems.
  6. Auto engines may need be replaced or rebuilt if the oil is allowed to breakdown to the point that it's protection properties are depleted, and causing the engines internal bearings to seize-up and producing a severe clatter or knocking in the lower part of the engine. (Photo: Engine oil sludge build up.

  7. Different brands of oil have different chemical additives that can shorten or extend the breakdown interval.
  8. Conventional motor oil, which is petroleum based, is susceptible to sludge and has a much shorter life than synthetics. 
  9. Not all synthetics are the same. Each has a unique chemical composition that allows for different time and mileage intervals between servicing. 
  10. The goal is to change the oil BEFORE it has completely broken down and overloaded with contamination.
