Few maintenance jobs are as important as changing your engine oil. It’s often put off, but it’s a cornerstone of your vehicle’s longevity and performance. Here’s how often to do it and why it matters.
How often should you change your oil?
It depends on your make, model and driving conditions, so follow the manufacturer’s recommendations. For most modern vehicles that means roughly every 10,000 miles (about 16,000 km) or every six months, whichever comes first. Check your owner’s manual for the exact interval for your car.
Why regular oil changes matter
Lubrication
Oil is the lifeblood of your engine. It lubricates moving parts to minimise friction and wear. Without it, components grind against each other, leading to early failure and costly repairs.
Heat dissipation
Oil also carries heat away from critical components. Fresh oil absorbs and transfers heat effectively, helping prevent overheating and damage.
Contaminant removal
Over time oil collects dirt, dust and metal particles, which leads to sludge and lower performance. Regular changes flush these contaminants out.
Engine health
Replacing old, degraded oil with fresh oil protects your engine against wear and keeps it running efficiently for longer.
Fuel efficiency
A well-lubricated engine works less hard and uses less fuel. Skipping oil changes increases friction and fuel consumption, so staying on top of it saves you money at the pump.
The bottom line
An oil change isn’t just a routine chore. It’s a simple, proactive way to protect the heart of your vehicle. Stick to the recommended interval and your car will run smoother for longer.
