Reduces maintenance costs

ISOSYN® technology, including a combination of high performance hydrocracked base fluids and carefully balanced metallic detergent and ashless dispersant additive system, helps provide excellent overall engine cleanliness in all service conditions. ISOSYN® technology also confers the high degree of soot dispersancy required to maintain oil drain intervals in modern engine designs. Highly effective oxidation stability helps protect against the formation of gums and varnish at elevated temperatures.

Prolongs engine life

High efficiency dispersant combination plus proven metallo-organic anti-wear additive system helps provide excellent protection against wear of critically loaded components under all operating conditions. Multigrade viscosity helps provide additional protection against wear at start-up and under high temperature operating conditions.

Preserves full power and performance

Outstanding metallic detergent additive system helps preserve full power and performance by providing excellent upper-ring-belt deposit control under the high temperatures encountered in turbocharged diesel engines.

Extends oil and filter service intervals

Highly effective antioxidant system inhibits the formation of sludge forming materials which can lead to premature oil thickening and filter plugging. Very effective dispersant system further assists by keeping insoluble contaminants finely suspended in the oil, minimizing their ability to block oil filters.

Applications

• Mixed fleets of diesel engines (high speed, four-stroke, turbocharged or naturally aspirated)
• Four-stroke gasoline engines in mixed fleets of diesel and gasoline engines
• Commercial road transport
• Off-highway vehicles and plant
• Agricultural tractors and farm machinery
• High speed diesel engines in marine service (e.g., fishing boat, river transport)
• Generator sets
• Mobile hydraulic systems (where oil type and viscosity are appropriate)
• Diesel engines utilizing diesel fuels with up to 35% biodiesel (B35)*

Service Considerations

For vehicles fitted with Diesel Particulate Filters (DPF), Delo 400 MGX SAE 15W-40 or Delo 400 SLK SAE 15W-40 should be selected in accordance with the manufacturer’s recommendations. The use of these low SAPS (sulfated ash, phosphorus and sulfur) products will maximize intervals between filter cleaning.

While modest by typical heavy duty diesel standards, Delo Gold Ultra has a level of phosphorus higher than permitted by certain recent standards for passenger car motor oils, e.g. ILSAC GF-5, and the ACEA “C” standards. Optimum life of catalytic emission control systems will be achieved by using oils of the performance standard recommended by the vehicle manufacturer.

When using with biodiesel blends containing >6% B100, monitoring oil condition is critical. Fuels with higher biodiesel content increase the risk of fuel dilution in the engine oil. This reduces the oxidation stability of the engine oil as biodiesel tends to oxidise more rapidly thus directly impacting the oil drain intervals. Biodiesel contents greater than B6 have a lower energy content than diesel fuel, which may result in slight horsepower loss and slightly increased fuel consumption.

Always follow OEM recommendation for appropriate fuel and engine oil selection.
