HOW CAN CHEVRON HELP? Visit www.ccjdigital.com/partner-solutions/chevron to learn more about how new PC-11 oils will meet the demands of operating conditions, and protect today's and tomorrow's on and off highway heavy-duty diesel engines. DID YOU KNOW? There are two subcategories of the new engine oils: • Oils in the API CK-4 category will be backward compatible with previous generation oils and will meet the needs of new and older engines in both on- and off-highway applications. • The API FA-4 oil category is designed for some heavy-duty on-highway diesel engines scheduled for introduction in late 2016 or early 2017. 3 Piston Deposits Piston deposits can be especially troublesome in engines because they can have a snowball effect: • They cause a loss of oil consumption control, which requires more make-up oil refills between changes. That adds costs not only for extra oil, but also for the labor to replenish it. • As engine oil is consumed it can accumulate in the emis- sion control system, driving more frequent Diesel Particulate Filter (DPF) regeneration cycles, which in turn means more frequent DPF cleaning intervals. • Additional regeneration cycles have a fuel economy penalty as well. For both on- and off-highway engines, new CK-4 and FK-4 engine oils address oxidation, wear protection and pis- ton deposit control needs to offset any potential downtime, maintenance and fuel costs. These oils won't sacrifice per- formance to meet emissions or fuel economy standards, and their advanced properties will provide vehicle and equip- ment operators with improved engine durability. 1 Oxidation Stability Performance tests for the new category of oils reflect the industry's focus on meeting the new challenges users face. Along with seven stringent tests used for current oils, the new oils also must pass two additional, very demanding tests. In particular, the aggressive Volvo T-13 test addresses oxi- dation, or oil's propensity to break down at high operating temperatures. Oxidation is especially harmful to engines because it causes oil to thicken and form deposits, and it fosters corrosion. Oxidation stability in the new engine oils is intended to address those issues. It is also a key factor allowing OEMs to consider extending recommended oil drain inter- vals. In fact, Chevron recently added an oxidation indica- tor to its recommendations for used oil analysis. Finding an oil that can maximize protection against oxidation will be crucial. 2 Wear Protection Maintaining the durability and reliability of your hardware is critical to keeping vehicles on the road. The new CK-4 and FA-4 oils have been developed to enhance engine longevity, measured as the time between overhauls. This is critical for the first owners of new engines as they plan for a pre-determined service life that eliminates the need to rebuild engines. It could also help boost the resale value of used equipment and make it more attractive to buyers.
