HDAX® 9700 is a premium performance, uniquely-designed engine oil recommended for dual fuel, medium-speed, four stroke cycle trunk piston engines burning natural gas with approximately 3 percent diesel pilot fuel ignition and up to 100 percent low sulfur diesel fuel (<500 ppm sulfur).Where to buy ›
Delivering value for you
HDAX 9700 Dual Fuel Engine Oil is a premium dual fuel gas engine oil with proven field service experience in dual fuel engines operating with diesel pilot ignition natural gas mode and up to 100 percent diesel mode for extended operational periods. It offers reliable deposit control, corrosion resistance and wear protection. Its hybrid technology is designed to control ash accumulation in combustion chambers to minimize risk of preignition and the rough engine operation that may be associated with engine misfire and detonation.
Fit for purpose formulation minimizes risk of rough engine operations that may result from misfiring or detonation when operating in dual fuel mode and using an elevated ash engine oil, as is typical of medium speed diesel engine oils.
A combination of premium base oils and high performance additives offer excellent oxidation and nitration resistance over extended oil life.*
Very low combustion chamber and piston deposits help protect liners from scoring and extend engine top-end maintenance cycles.
The unique ash containing additives in the oil allow minimal valve recession with low levels of combustion chamber deposits, to minimize the potential for pre-ignition and spark plug fouling.
Helps minimize oil consumption.
HDAX 9700 Dual Fuel Engine Oil is recommended for dual fuel, natural gas / ultra low sulfur diesel medium-speed trunk piston engines in coastal marine, inland marine, railroad and power generation applications. These high output engines may be turbocharged and equipped with exhaust catalysts systems. HDAX 9700 Dual Fuel Engine Oil has field service experience in: Wärtsilä dual fuel engines in coastal marine operations
