With growing concern over the environmental impact of diesel engine emissions, the Environmental Protection Agency (EPA) adopted stringent emissions standards for both NOX and particulate emissions. To further control emissions, the EPA also set lower limits on diesel fuel sulfur levels (15 ppm sulfur) that are used for on-highway and off-highway applications. Coolants Plus offers all grades of Heavy Duty Diesel Motor Oil to satisfy the most current EPA requirements, manufacturer's specifications and API CK4 service classification.
