Eurol Diesel Guard 15W-40 is a modern engine oil suitable for heavily loaded diesel engines with or without turbochargers and off-road equipment. Eurol Diesel-Guard 15W-40 amply fulfils the latest strict norms regarding deposits on the piston crown and on the rest of the piston. Due to the high temperature and ageing stability and because of the presence of strong deterging additives, Eurol Diesel-Guard 15W-40 ensures both the oil and the engine stay in good condition. Wear is limited to a minimum, even under the most severe working conditions, so the quality of Eurol Diesel-Guard 15W-40 is guaranteed during the full drain interval regardless the type of engine and working conditions. Eurol Diesel-Guard 15W-40 can be used for application in Euro II, Euro III and Euro IV and some Euro V engines, when fuels with high sulphur contents are involved. Eurol Diesel-Guard 15W-40 is not recommended for diesel vehicles with a Diesel Particulate Filter. Eurol Diesel-Guard 15W-40 is also recommended in gasoline engines, where SAE 15W-40 with API SL is prescribed.
