Maximize fleet performance: Essential engine maintenance best practices

Oct. 1, 2024
Maintaining heavy-duty engines is essential for fleet efficiency. Proper maintenance extends vehicle lifespan, reduces downtime, and minimizes repair costs.

Maintaining the longevity and optimal performance of heavy-duty engines is crucial for the efficiency and safety of your fleet. Proper maintenance not only extends the lifespan of your vehicles but also enhances their reliability on the road and reduces downtime. In this article, we will explore essential best practices that help your fleet achieve peak performance and keep your vehicles on the road smoother and longer.

Factors leading to engine wear

Engine wear can occur due to various factors and accurately identifying these is essential for mitigating potential risks.

  • Contamination: Contaminants play a significant part in engine wear. Dust, dirt and metal particles can infiltrate the engine, leading to abrasive wear and damage to vital components.
  • Engine Oil Condition: The condition of the engine oil plays a pivotal role in engine wear. Over time, engine oil can deteriorate, losing its effectiveness and ability to provide proper lubrication and protection.

Improper maintenance practices, such as neglecting scheduled oil changes or using the wrong grade of oil, can expedite engine wear and compromise performance. Adhering to maintenance best practices ensures that the engine operates at its peak performance and contributes to engine longevity.

Best practices for maximum fleet performance

1. Regular inspections

  • Schedule routine checks: Regular visual inspections can help you identify leaks, wear, and unusual noises in your vehicles.
  • Fluid levels & oil analysis: Monitor oil, coolant, and other fluid levels regularly. Monitoring oil levels and conducting oil analysis can help assess the engine oil's condition and identify any potential issues early on. Regular oil analysis can detect contaminants, assess oil condition, and identify any potential issues or abnormalities within the engine.

2. Scheduled maintenance

  • Follow manufacturer guidelines: Check OEM guidelines and adhere to the recommended service intervals for oil changes, filter replacements, and other maintenance tasks.

3. Oil changes

  • Regular oil & filter changes: Fresh, clean oil optimizes engine performance, protects against wear, and enhances fuel efficiency. Regularly changing engine oil and filters at recommended intervals is crucial for preventing contamination and maintaining oil quality.
  • Select the right engine oil: Choosing the right oil with the appropriate SAE viscosity grade and API designation is critical for matching the specific needs of your engines. Follow OEM recommendations and consider your vehicles’ operating conditions. Consider lower viscosity engine oils for emissions standards compliance and for their advancements in additives. The benefits of using lower-viscosity oils include cost savings, improved engine durability, and flexible formulation.
  • Use quality oil: Do not always go for the cheaper brands in the market because sometimes "cheap is expensive." Consider premium products like CITGO CITGARD Heavy-Duty Engine Oils. CITGO CITGARD HDEOs are engineered to improve engine durability, performance, and protection in old and newer engines. They are formulated for heavy, medium, and light-duty off-road and commercial on-road vehicles as well as stationary diesel engines. CITGARD Heavy Duty Engine Oils offers a wide product range for multiple engine types: gasoline, diesel, and mobile natural gas engines. They are guaranteed to reduce total operating costs and improve fuel efficiency and carbon footprint.

4. Monitoring systems

  • Use advanced diagnostic tools and technology: Invest in advanced diagnostic and predictive tools and technology to streamline maintenance processes. These tools can help quickly identify issues, perform accurate diagnostics, and optimize maintenance schedules. Preventative maintenance tools, like CITGO LubeAlert Fluid Condition Monitoring Service, can identify trends in a variety of equipment, providing valuable insights into equipment condition and conveniently helping to plan your vehicle's maintenance activities.

5. Vendor supplier relationships

  • Establishing strong relationships with your vendors and suppliers who specialize in maintenance for engines and equipment can be beneficial in the proper maintenance of your fleet. This can ensure timely access to expertise and technical support specific to each vehicle type. Contact your supplier about choosing the right heavy-duty engine oils that will work for your needs, such as the premium line of CITGO CITGARD HDEOs, for your optimized fleet operation.
