Pilot Flying J said it plans to have diesel exhaust fluid at the pump available at all diesel lanes by this fall.
The company said that after an investment of $165 million, it currently has DEF at the pump in 3,000 lanes at 400 of its 650 locations.
DEF is available at all Pilot Flying J locations in one-gallon and 2.5-gallon containers, the company said.
DEF is a necessary additive for diesel engines that have selective catalytic reduction systems to limit nitrogen oxide emissions.
