One of our top mechanics, JerryH20, posted one of the most-often asked questions of mechanics everywhere. The question in our Ask a Mechanic forum was “Oil Change Debate: 3000 or Ownr Manual Recommendation??” (See it here)
The reason this question is controversial is because of the change in thought from the “older school” mechanics and the newer ideas brought forth by manufacturers. The rule of thumb for mechanics has always been “3,000 miles” in between oil changes on gasoline vehicles. Today’s owner’s manuals in vehicles are often pushing that to 5,000 or more miles between changes.
