How to reduce maintenance costs of an ageing off-road fleet
28 Nov 2025
Purchasing new equipment and updating your fleet often comes with high capital costs. With this in mind, many fleet operators are choosing to extend the life of older equipment for longer than they may have in previous years.
However, as your equipment ages, its maintenance costs increase while efficiency declines. So, how can you get the most out of your ageing fleet?
In this blog, we’ll explore how you can keep older machinery productive and reliable with smart lubrication strategies and predictive maintenance.
Understanding the risks of ageing equipment
As equipment gets older, it becomes less reliable, and as a result, it comes with more risks that can cause project delays. From worn-out seals, damaged hoses and contaminated fluids to mechanical failures and deteriorating components, there are multiple risks to consider when prolonging the life of your fleet. Risks can include:
- Wear and tear of components
- Unplanned downtime and breakdowns
- Poor fuel efficiency
- Difficulty sourcing parts and accessing expertise
- Increased repair costs
- Reduced efficiency and productivity
- Leaks, pressure drops, and pump failures
However, there are plenty of ways you can proactively mitigate these risks with regular fluid checks and changes, along with implementing a preventative maintenance schedule. This is even more important with ageing off-road fleets, so you can stay ahead of potential issues and keep your fleet in top operating condition.
The role of lubrication in equipment longevity
The right lubricants are crucial for smooth operation, but they become even more important when dealing with ageing fleets that need increased protection. Lubricants add a protective coating to older components under a lot of stress to reduce friction between moving parts.
By using the wrong lubricants, you might experience oil oxidation, seal degradation and sludge build-up as well as performance issues such as increased consumption, temperature spikes and noisy operation. These can all lead to component failures, breakdowns and unplanned downtime, which can cause project delays. They also increase the total cost of ownership, as unexpected repairs, parts replacements, and downtime can significantly raise maintenance expenses over time.
High-performance lubricants are essential for off-road vehicles, offering formulations designed to withstand extreme conditions. For maximum protection, choose products that contain additives such as anti-wear agents, pour point depressants, corrosion inhibitors, and hydrophobic agents.
Smart maintenance tips for extending equipment life
The key to long-lasting off-road equipment is regular maintenance that keeps your machinery safe, compliant and reliable. To give your ageing fleet the best chance at longevity, follow these tips to extend equipment life:
- Run regular oil analysis
Through regular analysis, you can accurately monitor wear metals and oil oxidation, which can all lead to oil and component degradation. Regular analysis can also indicate whether your equipment is properly lubricated, as well as preventing over-lubrication, which can lead to failures.
- Upgrade lubricants for better protection
As equipment ages, the original OEM-recommended lubricants may no longer be available, or a higher-performance alternative may be better. Additionally, if components have been replaced, you should upgrade your lubricant to one that is better suited to the newer component.
- Don’t forget your cooling system
Often overlooked, cooling systems are exposed to a number of environmental factors that can deteriorate the system, including sea air, road salt, debris and chemicals. With this in mind, it is important to ensure cooling fluids and radiators are clean, efficient and leak-free.
- Stick to a strict greasing schedule
Grease is excellent for lubricating joints, bearings, pins and bushings, and it’s important to lubricate these components regularly. This can sometimes mean as often as every 6-48 hours. For older equipment with worn joints, look for quality greases with additives such as stabilisers, anti-oxidants, corrosion inhibitors, anti-wear and extreme pressure additives, solid lubricants and tackifiers.
- Inspect seals and filters more often
Seals can begin to corrode and wear, which often leads to leaks and equipment failures. Meanwhile, filters in older equipment can become clogged faster, so it’s important to check their condition and change seals and filters frequently before they lead to further damage.
- Log everything digitally
Apps, software and a predictive maintenance partner, like Gulf CARE, can help you track service and fluid change intervals. By logging maintenance checks and lubricant condition, you can ensure fluids are changed frequently enough to keep machinery running smoothly, while safely extending drain intervals, where appropriate.
When to re-evaluate lubrication choices
If your current lubrication choices are no longer offering the level of performance you require, it may be time to rethink your lubrication strategy. With older fleets, it’s likely that the original OEM-recommended lubricant is now outdated or underperforming, so switching to a suitable modern, compatible alternative could maximise uptime and increase longevity.
You should also consider switching up your lubrication choices if:
- Your machinery has undergone significant repairs or component replacements
- Your operating conditions have changed.
This ensures you are using the right lubricants for the operating temperatures and loads you are working with, so your fleet can perform at its best.
With Gulf CARE, we can assess your current lubrication strategy to make sure it aligns with the demands of your off-road fleet and keep it operating efficiently for as long as possible.
The road to longevity
Just because your off-road fleet is getting older, it doesn’t mean there’s not plenty of life left in it. With the right maintenance and a robust lubrication strategy, you can protect your fleet and still deliver a strong return on investment. From predictive maintenance and high-performance lubricants to fluid analysis with Gulf CARE, there are plenty of ways to extend the lifespan of an ageing fleet.
