Premium performance low-ash gas engine lubricant

HDAX ® 9200 Low Ash Gas Engine Oil SAE 40 is a premium performance low-ash, dispersancy and detergency type gas engine lubricant, offering robust component protection even under heavy loads, and is designed for use in natural gas applications.

HDAX 9200 Low Ash Gas Engine Oil SAE 40 is formulated with a premium base oil, offering extremely low sulphur, nitrogen and aromatic content, in combination with ashless dispersant and oxidation inhibitors, with a metallic detergent and anti-wear additive system. HDAX 9200 Low Ash Gas Engine Oil SAE 40 offers reliable corrosion resistance and good combustion chamber deposit protection. Good piston deposit control helps minimise ring sticking. HDAX 9200 Low Ash Gas Engine Oil SAE 40 oxidation and nitration resistance performance is designed to minimise viscosity increases in service.

Benefits

Oxidation and nitration resistance with base number retention offer extended drain in engines designed with a very low oil feed rate
Combustion chamber and piston deposit control, increased liner protection, sludge, wear and corrosion protection contribute to reduced downtime
Helps minimise valve recession, combustion chamber deposits and ash build up, helping minimise the potential for pre-ignition
Dispersant/detergent system and oxidation/nitration resistance helps minimise oil thickening and promotes engine cleanliness

Applications

HDAX 9200 Low Ash Gas Engine Oil SAE 40 is designed for the new generation of high output, turbocharged, low emission 4-cycle engines requiring low ash lubricants and is recommended for use in natural gas applications
HDAX 9200 Low Ash Gas Engine Oil SAE 40 also meets the more demanding needs of high speed 4cycle gas engines in cogeneration applications
HDAX 9200 Low Ash Gas Engine Oil SAE 40 is formulated to meet catalyst compatibility requirements
HDAX 9200 Low Ash Gas Engine Oil SAE 40 is suitable for use with fuels containing low levels of sulphur and chloro-fluoro-carbons (CFC). (In sour gas/high CFC applications, lubricants with higher base reserve may be required – for example, HDAX 9500)
