FUCHS Lubricants has introduced a new TITAN CARGO PRO 3977 SAE 5W-20 engine oil.  As part of the introduction of the Euro VI-d emissions standard for commercial vehicles by law MAN has published the MAN M 3977 specification. The specification has been specially designed to lower the fuel consumption and reduce CO2- and exhaust emissions in new MAN Euro VI-d engines.

To realise the savings, the specification requires a low viscosity engine oil with a viscosity grade of SAE 0W-20 or 5W-20 as well as a lowered HTHS value. In addition, MAN specific field tests have to be completed. Engine oils according to MAN M 3977 offer an excellent oxidation stability as well as an improved foaming behaviour, ensuring full utilisation of the specified service intervals.  

The MAN M 3977 specification can be used in selected MAN Euro VI-d engines and is not backwards compatible with older MAN specifications such as MAN M 3677.  

Product Profile and Application

TITAN CARGO PRO 3977 SAE 5W-20 is an Ultra High-Performance engine oil of the latest technology, which has been specially developed for use in MAN Euro VI-d commercial vehicle engines. In addition, TITAN CARGO PRO 3977 SAE 5W-20 meets the highest fuel economy requirements and achieves significant fuel savings. The low-ash additive technology provides excellent protection for modern exhaust aftertreatment systems such as particulate filters, exhaust gas recirculation systems and catalytic converters and promotes their reliable functioning over the entire lifetime.  

Furthermore, TITAN CARGO PRO 3977 SAE 5W-20 offers an excellent wear protection in comparison with other engine oils of higher viscosity grades.
