Understanding Delo 400 SLK SAE 15W-40 Understanding Delo 400 SLK SAE 15W-40

Equipment in industries like mining, quarrying & construction often runs the risk of unscheduled downtime due to the most extreme service conditions. Delo 400 SLK SAE 15W-40 with ISOSYN Advanced Technology is a premium quality ‘low-SAPS’ heavy-duty diesel engine oil specifically designed to lubricate a wide range of high-speed diesel engines requiring API CK-4, CJ-4, CI-4 PLUS / SM, or ACEA E9 performance lubricants operating under the most severe service conditions. 


Applications perfectly suited for Delo 400 SLK SAE 15W The applications where this low-saps heavy duty diesel engine oil works perfectly are many. Among those are commercial road transport, including the latest engines fitted with exhaust cleanup devices of all types. Also, vehicles meeting the most recent exhaust emissions standards, including US EPA 2002, 2007 and 2010, 2017 greenhouse gas (GHG 17) Euro IV, V and VI, and Australian ADR 80/02 and ADR 80/03 (for heavy duty) also work. It has also been observed that mixed fleets of both old and new equipment from European, North American and/or Japanese OEMs, stop-and-go vehicles in high soot loading service such as buses and waste collection trucks have been included in the list along with most diesel engine light duty vehicles, off-highway vehicles and plants including agricultural equipment, many heavy-duty gas-fueled vehicles, mobile hydraulic systems (where oil type and viscosity are appropriate) as well as diesel engines utilizing diesel fuels with up to 20% biodiesel (B20). 

Why Delo 400 SLK SAE 15W? There are many benefits attributed to this heavy-duty diesel engine oil. Among them are: -  

Minimized operating costs It has been noted that Delo 400 SLK’s exceptional soot dispersancy keeps soot in suspension, while minimizing filter plugging, cylinder head sludge, abrasive polishing wear and oil thickening. This heavy-duty engine also offers robust wear and corrosion protection of engine components due to its effective antiwar additive system which not only improves equipment durability and reliability but also reduced equipment downtime.  


Reduced inventory costs

Balanced formulation provides excellent overall performance in mixed fleets of different engine designs, including modern low emission diesel engines, allowing one oil for many services and reducing the chance of product misapplication. Moreover, it is backward compatible with previous API Oil Service Categories and engine models.


Maintenance of emission control system performance

Formulated with latest generation “low-SAPS” (sulfated ash, phosphorus and sulfur) technology containing reduced levels of metals, phosphorus and sulfur, Delo 400 SLK SAE maximizes the life of sensitive catalyst metals and the cleaning intervals of diesel particulate filters.
