Oil and Lubricant Shell Argina XL 40
Diesel Oil
Shell Argina XL Oil
Shell Argina XL is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual fuel. Argina XL is designed for conditions of very high oil stress and has been further optimised to improve deposit control.
Performance Features
Excellent engine cleanliness
Higher detergency than even Argina X, leading to exceptionally clean crankcase, valve deck and pistons. The formulation has been further optimised to reduce deposits in critical areas, e.g. piston undercrown.
Very high oxidation resistance
Longer oil life and greater resistance to oxidative thickening.
Extra high Base Number (50)
Longer oil life in engines where life is limited by depletion of Base Number (BN). In many cases a satisfactory equilibrium BN level can be maintained, in conditions where this would be impossible with a 40BN oil.
Full compatibility with Argina family
Argina XL can be used to top up engines already running on any other member of the Argina family, giving immediate control of BN without the need for an oil change.
Specifications and Approvals
Argina XL is approved by Wartsila and meets the engine test criteria for API CF.
