HEAVY DUTY EXTREME DIESEL ENGINE OILS API CK-4

Performance Specifications

Developed to meet the EPA's 2007 On-Highway Exhaust Emission Standards which require significant reductions in nitrogen (Nox) and particulate matter(PM) for 2007 model year trucks and maximum chemical limits on sulfated ash (SA), phosphorus (P), and sulphur(S) to address the emissions system compatibility and durability standards. The performance tests are a combination of existing CI-4Plus, CI-4 and CH-4 engine tests using today's diesel fuel (500 PPM's) combined with new engine tests using ultra low sulfur diesel fuel (ULSD=15 PPM) mandated for on road use. Considerable performance upgrade over CI-4 Plus in terms of emission control combined with superior protection of valve train wear, piston deposit control and soot handling capability.
