Caltex’s Delo® 400 SLK SAE 15W-40 engine oil will help your farm save costs while maintaining productivity.

Every farmer knows that machinery downtime spells trouble for the profitability and sustainability of a farm. Therefore, what is poured into the engines of machinery is extremely important. Astron Energy, the licensee of Caltex lubricants, understands this well. That’s why the company strives to offer only the best to its customers, such as Caltex’s Delo® 400 SLK SAE 15W-40 engine oil — a top-quality heavy-duty diesel engine oil.

Delo® 400 SLK, with advanced ISOSYN® technology, improves on the Delo® 400 MGX and now ranks first in Astron Energy’s premium series of heavy-duty diesel engine lubricants. 

Delo® 400 SLK is a low SAPS engine oil with API CK-4 specification. Low SAPS means it contains low levels of sulphated ash, phosphorus and sulphur. It is suitable for use with diesel fuel with a sulphur content of up to 500 ppm. The API CK-4 category remains compatible with older CJ-4 (from the Delo 400 MGX), CI-4 Plus, CI-4 (standard) and CH-4 categories.

Delo® 400 SLK SAE 15W-40 provides improved oxidation stability, allowing engines to have longer drain intervals. It also enables smoother and uninterrupted performance, even for vehicles operating under stop-and-go and extreme conditions.

Delo® 400 SLK’s exceptional anti-wear system provides protection for engine components against wear and corrosion. All of this means improved equipment reliability, reduced vehicle downtime and lower operating costs.

Delo® 400 SLK is capable of boosting the performance of various engine designs. This makes one type of oil suitable for vehicles from different original equipment manufacturers, from American and Japanese to European, old or new, with or without a diesel particulate filter (DPF) after-treatment device.

Thus, it helps reduce inventory costs for vehicle operators. This is attributed to Delo® 400 SLK meeting lubricant standards for newer engines (Euro IV and V standards) while remaining compatible with older engines. 

This engine oil offers the following benefits to customers:

Reduces operating costs

Exceptional soot dispersion keeps soot in suspension, minimising filter clogging, cylinder head sludge, abrasive polishing wear and oil thickening. It provides strong protection against wear and corrosion of engine components due to the effective anti-wear additive system. Therefore, it improves equipment durability and reliability while reducing machinery downtime.

Maintains emission control system performance

This engine oil is formulated with the latest generation low SAPS technology, which means reduced levels of metals, phosphorus and sulphur. Furthermore, Delo® 400 SLK extends the service life of sensitive catalyst metals and lengthens diesel particulate filter cleaning intervals.

Reduces inventory costs

Delo® 400 SLK is a balanced formulation that provides excellent overall performance in mixed vehicle fleets with different engine designs, including modern low-emission diesel engines. It allows for one oil for many services and reduces the risk of product misapplication. Additionally, this heavy-duty oil is compatible with previous API oil service categories and engine models.

Uses for vehicles on and off highways

• Commercial road transport with or without DPF.
• Old and new vehicles.
• Stop-and-go vehicles, such as buses and waste removal trucks.
• Most light-duty vehicles with diesel engines.
• Vehicles and facilities not used on highways, including agricultural machinery.
• Many gas-powered heavy-duty vehicles.
• Diesel engines using diesel fuel with up to 20% biodiesel (B20).
