SACRAMENTO – The California Department of Resources Recycling and Recovery (CalRecycle) has developed a website, www.CheckYourNumber.org, which allows users to look up OEMs' recommended oil-change intervals for vehicles.


SACRAMENTO – The California Department of Resources Recycling and Recovery (CalRecycle) has developed a website that allows users to look up an OEM’s recommended oil-change interval for vehicles, www.CheckYourNumber.org. The site asks for a vehicle’s make, model, and year before providing the recommendation. Using the site is free.
Fleet managers interested in finding recommended oil-change interval information can quickly look up vehicle-specific information, which makes it easier to benchmark oil-change related costs based on manufacturer recommendations.
Also related to oil changes, some fleets are seeing as much as a 20% discount in the cost of synthetic oils by working with certain national providers, according to a recent news story on oil-drain intervals.
