New Caltex Delo® 400 SLK SAE 15W-40 Minimizes Operating Costs for Truck Fleet Owners

Share This Post

As the economy opens up, transportation and logistics companies are ramping up operations while cutting down costs. The new Delo 400 SLK SAE 15W-40 is formulated with this in mind.

The Delo 400 SLK is able to boost the performance of various engine designs, allowing one oil for vehicles from different OEMs from America, Europe and Japan — new or old, with or without DPF aftertreatment device — thereby reducing inventory costs for vehicle operators. It enables today’s critical and in-demand commercial land transportation such as shipping and logistics trucks, buses, waste management trucks and off-road vehicles to achieve superb engine performance.

Performance edge for businesses

Introduced by Caltex Delo, which is marketed by Chevron Philippines Inc. (CPI), the new engine oil addresses the needs of diesel engines for on- and off-road vehicles. The Delo 400 SLK SAE 15W-40 is API CK-4 and offers improved oxidation stability, allowing engines to have extended drain intervals to enable smoother and uninterrupted operations even for vehicles operating under stop-and-go and severe operating conditions. The new Delo 400 SLK’s exceptional anti-wear system also offers robust wear and corrosion protection of engine components to bring overall improved equipment reliability, reduced vehicle downtime and lowered operational costs.

The Delo 400 SLK SAE 15W-40 has been field tested. During one such field trial, the 30 trucks field tested reached an extended drain interval of 60,000km to 80,000km, attesting to the product’s enhanced oxidation stability and wear protection.

“With the gradual reopening of the economy and easing of quarantine restrictions in the country, it is vital that companies ramp up their fleet while keeping the engines protected to better meet customers’ ever-increasing needs. When we upgrade our engine oils, we also future-proof our vehicles,” said Area Business Manager of Chevron Lubricants for Philippines Hafiz Nasar.

“At Chevron, we promise to constantly innovate and deliver next-generation products to keep our customers at the forefront of the latest technology developments,” he added.

Industry-leading, advanced formula

The Delo 400 SLK SAE 15W-40 is formulated with ISOSYN Advanced Technology, a unique integration of premium base oils, high-performance additives and the company’s formulation expertise infused into top-tier Delo products. Synthesized with additives for better soot dispersion, minimized filter plugging and sludge protection, the technology guarantees improved engine protection and longer oil life, thus providing Delo users with superior performance advantage.

The product is also made with the latest generation low-SAPS (Sulfated Ash, Phosphorus and Sulfur) formulation, enabling it to maintain emission control system performance that meets strict emission standards and to extend the life of sensitive aftertreatment devices and the cleaning intervals of engine filters.

The Delo 400 SLK’s balanced formulation can lubricate a vast range of high-speed engines requiring API CK-4, CJ-4, CI-4 PLUS/SN or ACEA E9 performance lubricants.

The Delo 400 SLK is available in drum and 18L pail packaging. Contact Caltex by sending an email to or talk to your sales representative to know more about how to avail of Caltex’ newest engine oil.
