Chevron HDAX LFG Gas Engine Oil is a premium quality, medium ash, dispersant/detergent type gas engine oil formulated especially for landfill gas and sour gas application.

It is formulated with ISOSYN™ base stocks and an additive package containing ashless dispersant, oxidation inhibitors, metallic detergents, a metallic antiwear additive, and a special combination of inhibitors to protect engines from the corrosive combustion byproducts encountered when landfill gas and sour gas are used.

Chevron HDAX LFG Gas Engine Oil provides outstanding corrosion resistance in landfill gas and sour gas applications, even when intermittent operation results in the formation of significant levels of acidic condensate. At 0.7 wt% ash, Chevron HDAX LFG Gas Engine Oil gives this performance with out the higher levels of combustion chamber deposits associated with other products used in this application.

It also provides an extra measure of valve protection for those four-stroke engines where medium ash oils are preferred (e.g., Superior and Waukesha).

Chevron HDAX LFG Gas Engine Oil provides excellent piston deposit control to minimize the possibility of ring sticking.

Applications

Chevron HDAX LFG Gas Engine Oil is especially recommended for four-cycle engines fueled by landfill gas containing elevated levels of Chloro-Fluoro-Carbons (CFCs) and sour gas applications where corrosive wear is a special concern. The low phosphorous level (270 ppm) of Chevron HDAX LFG Gas Engine Oil makes it compatible with Engelhard NSCR emissions catalysts.
