- Maximizes oil service life
Exceptional oxidation/nitration resistance and base number retention characteristics enable extended drain capability, even in engines designed to use a very low oil feed rate and in arduous landfill applications.
- Lowers operating costs
Long component life with outstanding piston deposit control, providing scuffing protection to the cylinder liners. Protects against abrasive wear.
- Minimizes maintenance costs
Promotes engine cleanliness optimized dispersant/detergent system allied to oxidation/nitration resistance, minimizes oil thickening and sludge formation, protecting against filter plugging, cylinder head sludge.
- Extends engine life to overhaul
Superior performing anti-wear additive protects against valve train wear and scuffing on parts operating under boundary conditions. Optimized ash level provides excellent valve recession control and controls potential for pre-ignition.
- Catalytic converter compatibility
Low phosphorus additive system optimized for use with catalyst systems.
- HDAX® 9500 is a superior quality, high performance dispersant/detergent type gas engine oil formulated specifically for landfill gas, biogas, digester gas and sour gas applications.
- HDAX® 9500 is formulated with premium base oils which contain extremely low sulphur, nitrogen and aromatics. It uses a premium additive package containing ashless dispersants, oxidation inhibitors, metallic detergents and a metallic antiwear agent.
- HDAX® 9500 provides excellent corrosion resistance, prevents deposit and sludge formation, and provides protection against wear and scuffing.
- HDAX® 9500 is designed for use in four-stroke engines burning landfill gas (including gas containing elevated levels of chlorofluorocarbons and/or siloxane), biogas, digester gas and sour gas.
- The combination of excellent base number retention and oxidation/nitration resistance allows HDAX® 9500 to deliver extended drain capability - even in applications where the oil feed rate is deliberately kept low, placing extra stresses on the lubricant. HDAX® 9500 prevents sludge formation on cylinder liners, which could interfere with oil flow and lead to higher oil consumption.
- Superior corrosion control ensures maximum liner life even in intermittent operation in sour gas applications, which may result in the formation of significant levels of acidic condensate.
- HDAX® 9500 provides excellent control of carbonaceous deposits on pistons, ensuring correct piston ring operation and providing scuffing protection to cylinder liners.
- Optimized ash level provides protection against valve recession, while avoiding the formation of ash deposits in the combustion chamber that could lead to pre-ignition.
