How often do you need to change your motor oil?

Χ a) 3,000 miles
Χ b) 3 months
✓ c) check your owner's manual

Needing to change your car’s oil at 3,000 miles is a myth. Auto makers now are recommending oil changes at 5,000, 7,000 or even 10,000 miles. Following the 3,000 mile myth generates millions of gallons of waste oil every year which can pollute California’s natural resources.

For more information, visit CalRecycle's website and the CalRecycle Check Your Number database to find the manufacturer-recommended oil change intervals for most vehicles (2000-2020).


  • Each year, millions of gallons of used oil are illegally poured down drains, sewers or disposed in the trash.
  • One gallon of used motor oil can pollute one-million gallons of drinking water
  • Used motor oil can be RE-REFINED into new oil that is just AS GOOD AS NEW.
  • Before it is drained, an oil filter can contain over a pint of used oil.
  • Oil filters containing oil SHOULD NOT be thrown into the trash. Remember to recycle!
  • It takes one gallon of used oil to produce 2.5 quarts of re-refined oil.
  • If all used motor oil generated by the public was collected and re-refined, it would provide enough oil for more than 5 million cars each year.
  • State agencies are now mandated to use re-refined oil, and have reported no problems resulting from its use.
  • The CA Highway Patrol spends about $110,000 on 22,000 gallons of re-refined engine oil and maintains 3,800 enforcement vehicles that drive more than 110 million miles per year.
  • Extensive laboratory testing and field studies show re-refined oil is equivalent to virgin oil.
  • Used oil can contain such contaminants as lead, magnesium, copper, zinc, chromium, arsenic, chlorides, cadmium, and chlorinated compounds.  Oil poured down drains or onto the ground or put in the garbage can work its way into our ground and surface waters and cause serious pollution.
