Roger England, chief research and development officer for Valvoline, takes issue with how some industry studies arrive at their conclusions regarding ash loading. England believes fuel quality may be a better focus for truck fleets and operators looking to reduce exhaust aftertreatment system issues and clogged DPFs.
“If you are burning 100 to 200 times more fuel than oil depending on your duty cycle, then a little change in that can be a lot bigger deal than a big change in something small,” England said. “Worrying about the chemistry of the oil is almost like the tail wagging the dog. It’s not where the issue is. The issue is around fuels and fuel quality.”
