Due to exhaust emissions limits mandated by the U.S. Environmental Protection Agency in 2007, demands on big-truck motor oils and coolants will be higher than ever.
Never fear; Chevron says it has the lubricants and coolants that will satisfy both the EPA and trucking industry needs. “I feel this is the most robust category of lubricants we’ve ever developed,” said J.A. McGeehan, Chevron’s global manager of heavy-duty motor oil, during his seminar, “How to Optimize Performance with the New API CJ-4,” held Thursday, Aug. 24, at the Great American Trucking Show in Dallas.
Chevron says its new CJ-4 big-truck motor oil will thrive in the higher heat created by ’07 engines. It also was designed to compensate for the reduced lubricity of the ultra-low-sulfur diesel fuel the new engines will use. Chevron’s CJ-4 has reduced amounts of sulfur and phosphates, too, which means less ash gathering in the diesel particulate filters all ’07 Class 8 on-highway trucks will have, the company says.
Chevron says its extensive testing – which included big-truck engines from Caterpillar, Cummins, Detroit Diesel, International, Mack and Volvo – shows that CJ-4 lubricates as well as or better than its predecessor, CI-4 Plus.
What this means, according to Chevron, are higher performance and lower costs. Major engine makers have not released oil-change information yet, but Chevron says its field test data has shown that using CJ-4 means reduced engine wear and longer intervals between oil changes and DPF cleanings.
Older engines also run fine on Chevron’s CJ-4, the company says. “CJ-4 is clearly backward-compatible and will provide the same or better lubrication as our previous motor oils,” McGeehan said.
CJ-4 hits the market Oct. 15, in Chevron’s Delo jug with LE for “low emissions” or Texaco’s Ursa jugs sporting EC for “exhaust compatible.”
