Idle costs more than you think: save fuel & protect your engine
You might not think twice about leaving your engine running while waiting for someone or sitting in traffic - but that simple habit could be quietly costing you.
According to energy and automotive efficiency experts, unnecessary idling can use up to 2 litres of fuel per hour, depending on the vehicle and conditions. That means wasted money, extra emissions, and avoidable engine wear - all from staying still.
Why idling is bad for your engine
When your engine runs without moving, it doesn’t reach optimal operating temperatures. This leads to incomplete fuel combustion, leaving behind carbon deposits that slowly build up on pistons, valves, and injectors. Over time, those deposits reduce power, clog critical systems, and cause your engine to work harder just to deliver the same performance.
Idling also increases wear on key components - particularly the engine oil, which can become contaminated more quickly when the engine isn’t running efficiently. The result? Higher maintenance costs, reduced lifespan, and poorer fuel economy.
The environmental and financial impact
Beyond the wear and tear, idling wastes fuel and contributes to avoidable emissions. A 10-minute idle every day adds up to over 60 hours of unnecessary engine time per year - that’s hundreds of dollars in wasted fuel and additional CO₂ released into the atmosphere. Multiply that by every driver on the road, and the environmental footprint is staggering.
How to protect your engine from everyday habits
The good news: you can counteract the impact of idling and everyday driving with simple, preventative maintenance.
Keeps injectors and intake systems free of carbon build-up, improving throttle response and efficiency.
NOTE: For petrol engines only.
Improves combustion, defends against ethanol-related corrosion, and helps petrol engines run smoother and cleaner.
Enhances combustion efficiency, cleans injectors, and reduces soot formation in diesel engines.
Reduces internal friction, improves compression, and extends the life of critical moving parts.
Small habits, big savings
Cutting down on idle time is one of the easiest ways to reduce waste and extend your vehicle’s life. Combine that with high-quality maintenance treatments, and you’ll enjoy sharper performance, longer engine health, and better fuel efficiency - no matter what or where you drive.
