Stop Waiting for Breakdowns: 3 Smart Fixes for Fleet Maintenance As a Fleet Technical Manager, I see a lot of money wasted on Corrective Maintenance (CM)—fixing things after they break. The most effective strategy isn't just following a schedule; it's using data to be smarter. Here are 3 key points about maintenance that really save money and improve uptime: The Hidden Cost is Downtime: When a truck breaks down, the repair bill is only 20% of the cost. The other 80% is the cost of the cargo delay, missed delivery, driver wages, and emergency response. Focusing on true Planned Maintenance (PM) is 5x cheaper than waiting for CM. Most companies use junior staff for oil changes and inspections. This is a mistake! You need your most experienced mechanics on the job. They are the only ones who can spot a small, early problem (like a tiny leak or a worn bushing) that prevents a major engine failure later. Quality of inspection is everything. Oil Testing is Better Than Mileage: Don't just change oil based on distance (km/miles). Use Oil Sample Analysis. This technical test tells you the real condition of the oil and the internal health of the engine. Sometimes, you can safely extend the interval and save money. Other times, you find a hidden problem before it damages the engine. This is a true GM-level cost control.
