Because of the higher levels of sulfated ash, phosphorus and sulfur used to formulate these previous types of oil, there is a risk of plugging the diesel particulate filters (DPF) and could cause more frequent maintenance of the low emission exhaust system. In addition, the older chemistries may not be able to handle the higher temperatures and increase in exhaust gas being pumped back into the crankcase on the new 2007 EPA complaint engines. CITGARD 700, CITGARD 700 Plus, and SynDurance meet the CJ-4 performance category.
