What is meant by the term “ash content” in natural gas engine oils?
The ash deposits are the residue remaining after the oil is burned during operation. The ash is made up of metallic detergent additives, such as calcium, barium and magnesium compounds. Lack of ash deposits can cause valve recession, which is the gradual wearing of the valve into the head, and if the ash level is too high, unwanted and harmful deposits can occur. CITGO offers Pacemaker Gas Engine Oils that are specifically formulated for all natural Gas applications including ashless, low ash, and high ash applications.
