“We believe that API CK-4 and FA-4 will deliver major efficiency and operational benefits for businesses operating heavy duty vehicles in North America, but more needs to be done to raise awareness of this, which is why we have introduced the website,” Howard McIntyre, vice president for lubricants at Suncor, said in a statement.

“End users will need to consider which oil category is most suitable for their vehicles depending on age, application and operating conditions. The new DURON website will help them choose with confidence and understand the enhanced benefits such as extended drain intervals, higher fuel economy or extreme temperature protection they will receive,” McIntyre said.
