Reliability and durability are our priority

Caltex Lubricants stands for one thing above all else – reliability. Properly lubricating the inside of a heavy duty diesel engine requires more than just creating a protective film. Delo heavy duty engine oils provide soot dispersancy, wear protection and sludge control, to guard against loss of engine life and help reduce fuel and oil consumption. Additionally, Caltex Delo products deliver integrity and performance as proven by various bench testing results. Caltex industry leading lubricants have logged countless hours providing protection to diesel engine parts in heavy duty vehicles.

Keep your fleet running longer

Managing a fleet of trucks, buses or coaches is challenging, as these vehicles need to operate daily to stay profitable. We provide high-quality Caltex products and services to help keep your fleet moving forward and running longer. One of these services is our oil analysis programme with physical and chemical tests of oils in use. It's designed to help fleet operators track the health of their lubrication system, optimise performance and identify potential issues before they cause major failures – reducing unnecessary maintenance and vehicle downtime.

Our oil analysis programme

For fleet operators aiming to increase productivity and optimise vehicle performance, monitoring oil condition is an effective method for tracking the health of the lubrication system. Regular fixed service intervals can sometimes lead to oil drain intervals that are shorter than necessary and parts being changed before they need to be.

Our oil analysis programme offers a simple and effective way for monitoring vehicle performance. By regularly analysing oil samples, you can optimise oil change intervals, identify lubrication needs and understand the changing conditions within your trucks and buses. This information allows for precise maintenance scheduling, reducing downtime and minimising the risk of major failures.

Benefits include: 

• Optimised oil changes: Regular oil analysis ensures that oil drain intervals are based on actual usage and condition, preventing premature changes and reducing unnecessary maintenance costs.
• Enhanced truck and bus performance: By monitoring lubrication needs and changing conditions within vehicles, the programme helps maintain optimal performance, extending component life and preventing costly failures.
• Improved maintenance scheduling: Oil analysis provides actionable insights to refine service intervals, minimise downtime, and protect against unexpected breakdowns, keeping your fleet operating efficiently.
