Fleet operators demand better and better fuel efficiency and, beginning with model year 2017 heavy-duty trucks, federal regulators will as well. For the first time in 10 years, OEMs, oil marketers, and standards organizations are coming out with a new category for heavy-duty diesel engine lubricants designed to maximize fuel efficiency from the latest in powertrain technology.
Lubricants: The next oil change
“It's kind of confusing in the marketplace because we’re going to end up with 5W-30s or 10W-30s that fall into both categories and they're going to be different. This is new territory for us. Historically, all the heavy-duty diesel engine oils have been in the higher HTHS category. Part of the consumer education process that the industry will be undertaking is to help them understand that there are multiple oils that would carry the same viscosity grade.” - Roger Gault, Truck & Engine Manufacturers Assn. vice president for regulatory activities
