economy, and rightfully so — but we're also very cognizant that the engine is king," says Barnaby Ngai of Petro-Canada, which makes Duron brand lubricants. "At the end of the day, you're not going to save much money if the engine isn't moving." Although we don't know the exact specifications of the new oil category yet, both Chevron and Shell this year highlighted the protection possibili- ties of a lower-viscosity oil through engine teardown events. Chevron conducted a live teardown of a Detroit DD15 engine, with more than 400,000 miles of service using Delo 400 XLE 10w-30, during the Mid-America Trucking Show in Louisville, Ky., in March. "There's a misconception that lighter viscosity oils don't offer the same level of protection as heavier oils," said Jim Gambill, Chevron's North America commercial and in- dustrial brands manager, at the show. "We're here to dispel that myth. "What we're looking for is wear that can be seen in touch areas like the cam, cam lobes, and some of the bearing materials," he explained, showing off the parts that were coming off the engine. "The wear was really good. We're also looking for deposit control around the ring and piston; the rings were really clear. The crosshatching inside was fully intact — no sign of early wear there." In May, Shell shared with journal- ists its teardown resulting from a fleet field test comparing Shell Rotella 15w-40, 10w-30, and an experimen- tal 10w-30 with viscosity properties similar to what is expected in the new category.

Shell laid out the parts for inspec- tion in the Clarke Power shop in Greensboro, N.C., and dared truck- ing journalists to tell the difference. They couldn't. Howard Hill, engineer, lubri- cant technology, who's in charge of Shell's field test program, noted that the highest iron wear rates they saw were about 100 ppm, and Detroit Diesel's condemnation level is 250 ppm, so it was well under that con- demnation level. Both Chevron and Shell took par- ticular note of the lack of any sludge buildup anywhere in the engines. "We like how the oils are perform- ing," said Shell's Hill. "We're very, very pleased with the new technol- ogy, and it's proven itself out with the engine inspections." n www.truckinginfo.com JULY 2014 • HDT 61
