“HDAX 9700 provides the market with a fuel-agnostic lubricant, engineered to support both distillate and gaseous fuels without compromising on performance,” said Luc Verbeeke, senior staff engineer at Chevron Marine Products. “Operators who are investing in dual-fuel medium speed engines need confidence that their lubricant will perform across fuel types, eliminating the need to change lubricants with each fuel source selection.” 

Developed in response to stricter emissions regulations and the rise of dual-fuel engine technology, HDAX 9700 is a premium SAE 40 oil formulated to protect medium-speed four-stroke engines running on diesel, LNG, CNG, biofuels, methanol and ammonia. Its hybrid additive technology effectively controls ash accumulation, improves resistance to oxidation and nitration, and helps prevent corrosion – all with low oil consumption.
HDAX 9700 is also an excellent choice for engines equipped with exhaust aftertreatment systems such as Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR).

The lubricant has been validated through over 20,000 hours of field testing on a Wärtsilä dual-fuel vessel and is the first and only lubricant to receive time-unrestricted approval from MAN Energy Solutions for use in four-stroke engines operating on either LNG or low-sulfur distillates (≤0.10% S).
