Truck ia a 2006 Freightliner M2 with the CAT C7 engine/HUEI. I change the oil every 12k - 14k kms to keep the HUEI happy. My cost on both oils are about the same, $75 for 20l. Also use this oil in a Toyota forklift. Is one of these oils significantly better than the other? I have been using the Delvac for many years.
