\n

The hidden cost is in the engine hours. Every minute the truck sits idle adds wear, brings servicing closer and reduces the productive life of the vehicle without moving a single load.<\/p>\n

Most of the cost of fleet idling never appears on a fuel receipt. Fuel prices fluctuate and Saudi’s extreme climate increases wear on vehicles, but idling is one of the few operating costs site managers can actively reduce without slowing the work. The challenge is that it often goes unnoticed because the real cost sits in engine hours and maintenance rather than on the fuel bill.<\/p>\n

Idle hours build up in loading queues, crew breaks, shift handovers and equipment waiting for other equipment. What feels like normal site operations can quietly add hundreds of unnecessary engine hours over the course of a year.<\/p>\n

Where Idle Hours Hide on a Compound<\/h2>\n

Idle time rarely comes from one long delay. It builds up across dozens of everyday site activities that feel normal but quietly add unnecessary engine hours.<\/p>\n

The most common sources include:<\/p>\n<\/div>\n

\n
1<\/span><\/p>\n

Loading and tipping queues are the largest source of idle time.<\/b> A truck waiting to load or tip keeps the engine running to maintain cab cooling, air pressure and its position in the line. Some of this is unavoidable, but most of it comes from queues running longer than anyone has timed.<\/p>\n<\/div>\n

2<\/span><\/p>\n

Crew breaks are taken with the engine left on.<\/b> In peak Riyadh heat, the cab becomes unworkable within minutes, so drivers keep the air conditioning running during breaks. Some of this is a necessary heat safety requirement, but the waste comes from engines running in empty, stationary vehicles.<\/p>\n<\/div>\n

3<\/span><\/p>\n

Shift handovers happen with engines running.<\/b> A few minutes at each handover, twice a day across a six day week, adds up to a steady block of idle time before queues or breaks are even considered.<\/p>\n<\/div>\n

4<\/span><\/p>\n

Equipment waiting on equipment is common on Riyadh construction compounds.<\/b> A tipper waits for an excavator and a water truck waits for a pump connection. The engine stays on by default, because switching it off is rarely assigned or enforced.<\/p>\n<\/div>\n<\/div>\n

Why Idling Costs More than the Diesel<\/h2>\n

Fuel is the smaller part of the cost. The bigger cost is engine hours, which do not appear on fuel reports.<\/p>\n

Start with fuel, as it is the most visible part of the cost. The US Department of Energy estimates idle burn for a heavy diesel truck at roughly 3 litres per hour. At SAR 1.79 per litre, that works out to about SAR 5 per idle hour.<\/p>\n

A heavy truck idling for three hours a day, six days a week, burns roughly SAR 90 of diesel each week. Across a fleet of 100 heavy trucks, that’s around SAR 40,000 in fuel every month before a single load has moved. And that’s before accounting for the additional servicing, maintenance and engine wear created by those idle hours.<\/p>\n

These figures are based on heavy trucks. Light vehicles consume considerably less fuel while idling, so the actual cost will depend on your fleet mix.<\/p>\n

Engine hours are a hidden cost. Most plant and modern trucks are serviced based on engine hours from the onboard computer, not distance travelled. That means idling adds wear without moving the odometer, bringing servicing forward sooner than expected.<\/p>\n

Three hours of idling a day adds up to roughly 900 engine hours a year on a truck that has not moved. On vehicles still serviced mainly by distance, that same idle time simply shows up as wear between service intervals instead.<\/p>\n

Long periods of idling mean the engine often runs below its optimal operating temperature. That reduces combustion efficiency and can dilute the engine oil with unburned fuel. On newer trucks, lower exhaust temperatures can also prevent the diesel particulate filter (DPF) from regenerating properly.<\/p>\n

The US Department of Energy notes that reducing idle time lowers engine wear and the maintenance costs that follow, particularly for heavy duty vehicles. Saudi diesel remains cheaper than most markets, but since the 2022 pricing reform prices have risen from SAR 0.63 to SAR 1.79 per litre, meaning fuel now makes up a larger share of the idle cost than it once did.<\/p>\n

How to Track Idle Time per Vehicle<\/h2>\n

Without telematics<\/a>, a site manager is left guessing which trucks idled the most last week.<\/p>\n

Telematics tracks each vehicle by recording engine running time against GPS movement<\/a>. If the engine is running but the vehicle is not moving, it is counted as idle and can be broken down by vehicle, shift and driver. The system can also send an alert when idling goes past a set time, such as 15 minutes, so a supervisor knows immediately instead of finding out a week later.<\/p>\n

A yard geofence is used to separate on site waiting from road driving, so a truck queuing inside the compound is not treated the same as a truck stuck in traffic.<\/p>\n

Saphyroo’s Drive360<\/a> is designed for Saudi site fleets, showing idle time by truck and driver and sending alerts as it happens rather than a week later. A compound geofence separates on site idling from road driving, so the data you act on reflects what is actually happening on the ground.<\/p>\n

How to Reduce Idle Time Without Slowing the Site<\/h2>\n

Not all engine running is waste. A water truck powering its pump or a power take off (PTO) operating equipment is doing productive work. The goal isn’t to eliminate idling, it’s to identify and reduce unnecessary idle time before it becomes avoidable fuel, maintenance and engine hour costs.<\/p>\n<\/div>\n

\n
1<\/span><\/p>\n

Set an idle threshold and trigger alerts.<\/b> A 15 minute alert turns idle time from a passive record into something a supervisor can act on immediately.<\/p>\n<\/div>\n

2<\/span><\/p>\n

Start with the worst offenders.<\/b> The data ranks every vehicle by idle hours and the highest numbers usually come from trucks on loading and tipping faces, not a fixed set of \u201cbad\u201d machines. The focus should be on fixing the task or delay, not blaming the truck.<\/p>\n<\/div>\n

3<\/span><\/p>\n

Separate productive running from dead idling.<\/b> A water truck running its pump is doing work and should not be counted as idle, whereas a tipper sitting in a queue waiting for work is the real source of wasted time.<\/p>\n<\/div>\n

4<\/span><\/p>\n

Treat cab cooling correctly.<\/b> Keeping an occupied cab safe in peak Riyadh heat is a safety requirement, not waste. The waste is engines left running in empty cabs or left on, out of habit, when cooling alternatives are available nearby.<\/p>\n<\/div>\n

5<\/span><\/p>\n

Focus coaching on the few drivers who account for most idle time.<\/b> Once ranked, the data makes it clear who is driving the problem, turning the conversation into specific action around drivers and shifts instead of general instructions.<\/p>\n<\/div>\n<\/div>\n

None of this requires a system to start. Before buying anything, compare the engine hour meter with the odometer on your three busiest trucks. A high ratio of engine hours to distance is your idle problem and you can size it in five minutes with a torch and a notebook. The tools only matter once you know the number is real.<\/p>\n

Take the water truck at the gate as an example. Two hours there uses about SAR 10 of diesel and adds two hours to the service clock for every truck in the same position. The fuel bill is unavoidable, but the engine hours are the cost you can actually choose to see and manage.<\/p>\n<\/div>\n
