New Motor Oil For Latest Diesel Engines

New Motor Oil For Latest Diesel Engines ENGINES Engines 31-3-38 If you plan to buy a diesel-powered vehicle in 2007 or beyond, be aware that you'll need to use a new heavier duty motor oil designed for low-emission diesels with particulate traps. While specially formulated for the new engines, the CJ-4 oils are also backward compatible to older engines. "All industry experts say that the new CJ-4 category is the most robust category of lubricants from a performance standpoint that has ever been put out in the marketplace," says Bob Theisen, technical service manager, CHS. "They offer great improvements in wear protection, oxidation protection and in ability to handle soot. That is as important for old engines as new." The new oils have lower levels of sulfated ash, phosphorous and sulfur (SAPS.) Higher levels of SAPS can clog the particulate filter on the new engines. In the past, it was SAPS that neutralized acids and prevented wear. The new ultra low sulfur diesel fuel reduces acid levels in today's fuel, and other additives replace the benefits lost with lower levels of SAPS. The new oils are expected to cost 10 to 15 percent more than previous lubricants. "They're definitely worth the increased cost," says Theisen. "Ultra low sulfur diesel fuel has gotten into the market a lot quicker and is distributed a lot wider than people thought." CHS, marketer of Cenex lubricants, is so confident in the quality and value of the new oil formulation, it is all they plan to market. Other oil companies plan to continue offering the older generation oils. Mike Svobodny of Greenway Co-op in southern Minnesota says, "There are very few of the new engines out there yet. Until you have the 2007 engine, you can continue to use the older oils, but we will see a transition to CJ-4 oils as time goes on." Theisen says CHS is working to confirm the potential for extended drain use of the new lubricants. "We are working with customers on used oil analysis," he says. "We can't make a blanket statement that time between drains will dramatically increase, because it depends on how the tractor or truck is used. We can say it adds a good reason to start making more use of used oil analysis programs."
