Mobil has announced their line of PC-11 (CK-4, FA-4) Mobil Delvac diesel engine oils for heavy duty trucks.  The new classifications take effect in December 2016 and are designed to outperform current CJ-4 oils by increased oil drain intervals and boosting uptime.  Mobil is transitioning their current line of CJ-4 Motor Oils to the CK-4 classification, which can still be used in older vehicles and prior classifications, as well as introducing a related but separate line to meet new FA-4 specifications for improved fuel economy in new engines with limited backward compatibility.

The CK-4 motor oils include Mobil Delvac 1 ESP 5W/40 full synthetic, Mobil Delvac Extreme 10W/30 and 15W/40 synthetic blend, and of course Mobil Delvac 1300 Super 10W/30 and 15W/40 for premium conventional that meets or exceeds OEM performance.  MobilFleet customers will also be transitioning to new Mobil HDEO available in both 10W/30 and 15W/40 weights which will meet CK-4 requirements.

For our customers who receive bulk product, deliveries after December 1st will meet the the new CK-4 requirements while package goods will transition as inventory is depleted.  For questions or more information, please contact your Asheville Oil Company sales representative or call our office at 828-274-7978.
