Most failures don’t begin with a loud bang. They start with something deceptively small: a lubricant that’s contaminated, breaking down, or simply the wrong fit for the job.

Even the strongest RCM (reliability centered maintenance) programs can get tripped up by wrong lubricants, inconsistent schedules, contamination, or oil analysis that gets skimmed instead of truly interpreted. When lubrication slips, the entire maintenance program feels it.

In this post, we'll break down why lubrication still ranks among the top causes of asset failure, how it connects to a successful reliability centered maintenance program, and why pairing oil analysis with vibration monitoring gives you the most complete, condition-based view of your asset health.

‍

What Is Reliability Centered Maintenance (RCM), and Where Does Lubrication Fit?

A reliability centered maintenance (RCM) analysis is a highly customized process with a unique approach for each asset that's tailored to its usage, key component parts, and unique threats to usability. The RCM process is designed to:

• Identify system functions
• Pinpoint the critical failure modes that threaten those functions
• Evaluate the consequences of those failures
• Determine the most cost-effective maintenance strategies to prevent them

‍

Teams implement reliability centered maintenance to ensure that maintenance efforts are both efficient and effective, reducing costs while maximizing asset performance. Done well, an RCM program drives all these gains while giving maintenance teams a clear path toward continuous improvement.

But here’s the part many organizations miss: lubrication affects nearly every major failure mode associated with rotating equipment. If lubrication fundamentals aren’t solid, no RCM strategy—no matter how thorough—can deliver its full value.

Why Lubrication Still Tops Failure Lists

Lubrication is so foundational that it quietly shapes every metric: performance standards, maintenance costs, asset availability, and long-term system reliability. Yet it’s still one of the most overlooked maintenance activities. Even the most skilled maintenance teams can underestimate what poor lubrication does across the production line.

‍

The hidden costs of poor lubrication

Most lubrication-related failures are preventable. The costs stack up as small errors such as contamination, incorrect viscosity, and missing early wear indicators compound over time.

• Lost production from unplanned downtime
• Increased scrap and product spoilage
• Higher repair costs and spare parts usage
• Emergency labor and overtime
• Excess energy consumption from increased friction
• Accelerated wear that shortens the useful life of critical assets

‍

Here are some eye-opening estimates of the damage that lubrication issues cause:

How lubrication directly shapes RCM outcomes

Clearly, lubrication is a primary failure driver. And when you think in terms of RCM evaluation criteria, the condition of your oil is directly tied to:

• Functional failure (loss of required function)
• Failure modes (bearing wear, overheating, contamination, viscosity breakdown)
• System failures (cascading breakdowns across interconnected assets)
• Cost effectiveness (predictive vs. preventive maintenance vs. reactive repair costs)
• Maintenance performed proactively rather than after failure occurs

‍

This makes lubrication a strategic leverage point. Following lubrication best practices and going beyond the red, yellow, and green in your oil analysis reports is key to optimizing RCM program results.

Oil Analysis: The RCM Multiplier Most Teams Underutilize

‍

A reliability centered maintenance strategy depends on choosing the right maintenance tasks for each asset. Oil analysis is one of the most powerful condition-based maintenance tools you can use to support that process.

Without comprehensive, in-depth oil analysis, you're operating with visibility gaps. Red/yellow/green labels tend to oversimplify asset condition and hide early, actionable warnings such as subtle changes in wear metals, viscosity shifts, or contamination levels that often never trigger a color change. And without the ability to identify trends, teams can’t see accelerating wear or emerging failure modes.

‍

When oil analysis becomes a strategic, trended data source, you'll have:

• Visibility into wear particles indicating internal component wear
• Insights about contamination (water, dirt, coolant, cross-contamination)
• Lubricant health including oxidation, additive depletion, and viscosity changes
• Remaining useful life estimates that help you schedule maintenance with precision

‍

Here's a real-world example of the value of oil analysis. When early warnings in oil analysis data were overlooked, a $150,000 gearbox lost over half its value due to a wear rate running 261% above normal. That's over five years of asset life lost, when a timely response at the first signs of low viscosity and particle buildup could have prevented the damage.

Oil analysis, interpreted correctly and acted upon quickly, changes the entire trajectory of asset life—and your maintenance costs along with it.

Why Vibration + Oil Analysis = Reliability Centered Maintenance at Its Best

Vibration monitoring and oil analysis are complementary tools that work together to provide a holistic view of asset health. Vibration monitoring tells you what is happening mechanically, while oil analysis shows you why.

‍

When both signals are integrated in the same condition monitoring program, teams close the visibility gaps that lead to reactive maintenance. In one case, $897,600 was saved and 336 hours of downtime were avoided when vibration flagged abnormal wear and oil analysis confirmed contamination and degraded viscosity in an extruder. This is a classic example of how proactive, condition based maintenance tasks outperform run-to-failure approaches every time.

How Lubrication Strengthens an Entire Reliability Centered Maintenance Program

A strong lubrication strategy supports every pillar of RCM.

1. Reduces maintenance costs

With correct lubrication and trended oil analysis, you eliminate premature wear and extend the intervals between overhauls, directly cutting repair costs and unnecessary maintenance activities.

‍

2. Improves equipment reliability

Because most rotating equipment failure modes originate with friction, wear, heat, or contamination, lubrication directly improves asset condition and system reliability.

‍

3. Helps identify failure modes early

Oil analysis reveals early evidence of the most common RCM failure modes (bearing wear, gear degradation, contamination, oxidation, viscosity breakdown) long before failure occurs.

‍

4. Enables condition based maintenance

RCM emphasizes suitable proactive tasks, not blanket scheduled maintenance. Oil analysis gives you the real-time condition data required to perform the right task at the right time.

‍

5. Supports continuous improvement

Once lubrication performance is monitored, trended, and tied to KPIs, teams can refine processes, improve training, reduce maintenance backlog, and accelerate RCM program maturity.
