Check Your Number” encourages motorist to look up the recommended oil change interval for their automobile instead of defaulting to the old standard of 3,000 miles. Did you know that with today’s new technologies, many car makers confirm automobiles can now maintain top performance with longer space between oil changes? So it makes economic and environmental sense to “check your number” and be sure you are not changing your oil too soon, creating unnecessary waste of money and resources. Check your owners’ manual, or simply click on www.CheckYourNumber.org to easily find out for free the recommended time to change the oil on most vehicles made from 2000-2015.
