Extended Oil Change Intervals – Part 1

Extended Oil Change Intervals – Part 1

There is a new public service campaign being conducted by the California Department of Resources Recycling and Recovery (an essential gov’t function no doubt 😉 ), regarding engine oil change intervals called “Check Your Number”.


The campaign seeks to challenge the 3000 mile oil change habit that a claimed ten million people still follow despite huge advancements in motor oil, metallurgy, engine technology, oil life monitoring and filtration. Most vehicle manufacturers for the last decade, or more in some cases, have recommended oil change intervals at 5000 to 7500 miles on conventional (non-synthetic) oil. Some manufacturers that run synthetic oil as a factory fill, recommend as long as 15K miles.

So why to this day why do nearly a third of all Californians still shell out the money and time changing their vehicles’ oil every 3000 miles? I have heard a few reasons from customers, some of them highly rational, but I’d love to hear from you guys why you do or don’t change your oil every 3000 miles.
