Logan Ruta HD LS is an advanced low SAPS heavy-duty diesel engine oil specially formulated for Euro V & Euro VI engines fitted with emission control systems using DPF, EGR or SCR technology. It is also suitable for previous generation turbocharged and normally aspirated diesel engines used in North America, Africa and Europe that run on low sulfur diesel. Logan Ruta HD LS 15W-40 CK-4 provides exceptional wear and corrosion protection for all engine parts and prevents combustion soot. This lubricant is developed for engines running on low and ultra-low sulfur diesel. When engines are running on high sulfur diesel, the drain interval should be reduced by at least 50% of the engine manufacturer’s recommendation.
