HDAX 5100 Ashless Gas Engine Oil SAE 40 is recommended for gas fueled engines manufactured by: Ajax Caterpillar (except 3400, 3500, 3600) Clark-Dresser Cooper Bessemer (two-stroke) Dresser-Rand (Ingersoll-Rand) Categories I, II Fairbanks-Morse/MEP Waukesha VR and Intermediate/Clinton Worthington (two-stroke). Total Base Number TBN is formulated into the finished lubricant to counteract the by-products of combustion/ acids. Formulators aim for a relatively slower TBN depletion rate, which is a function of a balanced additive package, base oil quality and formulation experience. Field Test Performance In a 6,000 hour field test in a GE Jenbacher type 4 landfill site gas engine run at 1,500 rpm, HDAX 6500 LFG Gas Engine Oil SAE 40 demonstrated an average oil drain interval of 1,200 hours.

Understanding Value Drivers in Maintenance of Natural Gas Engines For Typical Operations: Downtime directly impacts production and revenue. Unscheduled downtime costs due to engine failures are significant, due to complexity involved with repairs. Lubrication preventative maintenance tasks are difficult to manage in remote locations. Due to size of engines, lock-out process and remote locations, safety is often a major concern for the mechanics. Engine overhaul costs are expensive extending time to overhaul by one year or more is significant to lowering total cost of ownership (TCO).
