Motor/Engine Oil (Re-refined)

Industrial Consumer

Changing motor oil every 3,000 miles no longer applies to most cars.  Many cars can be driven up 15,000 miles before needing an oil change.  Motor oil is one of the largest hazardous waste streams.  See when your car's manufacturer recommends changing your oil.  And get frequently asked questions.

Criteria for Motor/Engine Oil (Re-refined)

Criteria for Suggested products:

Motor/engine oil must contain a minimum of 75% re-refined base stock (unless the products falls under one of the exceptions contained in this document).  Bidders must identify the manufacturer which is providing re-refined base stock and include in their response to the RFR, a letter from said manufacturer certifying the actual re-refined content and that all re-refined base stock meets all requirements of this RFR. 

The only exceptions are:

  • 5W20, which City staff can use on a Limited Use basis.  Thus, a re-refined base with a minimum of 50% re-refined base stock is desirable, but not required.  
  • 5W30 oil, where the base stock must be a minimum of 50% re-refined.  
  • It is desirable that the vendor offers a closed-loop system wherever possible and feasible for collecting used motor oil for the sole purpose of recycling the product into new motor oil.
