Not sure when your car is due for an oil change? You’re not alone. While many modern vehicles come with dashboard reminders, those alerts don’t always come at the ideal time — and some older vehicles don’t have them at all. The good news is, your car gives off clear warning signs when it’s running low on clean oil. You just need to know what to look for.
At EuroMechanic – Brock Road Garage, we’ve helped hundreds of Guelph drivers avoid costly repairs by catching oil issues early. Here are five signs that it might be time to schedule your next oil change in Guelph.
1. The Oil Light or Check Engine Light Is On
Let’s start with the obvious one. If your dashboard oil pressure light is on — or your “check engine” light suddenly appears — it’s time to take action.
The oil pressure light usually means your vehicle has low oil levels or poor oil circulation. Both conditions can lead to engine overheating, increased friction, and serious damage. If your oil is dirty or too low to register, your engine isn’t being properly protected.
Ignoring that little red light can lead to big trouble. Bring your vehicle to a trusted mechanic in Guelph for a quick inspection before minor wear turns into a major issue.
2. Engine Noise That Wasn’t There Before
When your engine runs on fresh oil, everything sounds smooth and quiet. But as that oil breaks down, friction between moving parts increases — and you might start hearing:
- Ticking or tapping sounds at startup
- A louder idle than usual
- Knocking sounds when accelerating
These noises are signs that your engine is no longer being properly lubricated. Fresh oil acts as a cushion between metal components. When that cushion wears thin, things get noisy — and expensive.
3. Dark, Dirty, or Gritty Oil
You can check this one yourself. Pull out your oil dipstick and take a close look.
Fresh oil has a clear, amber colour. Dirty oil looks thick, dark, and sometimes gritty — a sign that it’s full of contaminants like dust, metal particles, and engine debris.
If your oil is dark and opaque, it’s time for a change. Keeping clean oil in your engine is one of the most important steps you can take to extend its life and performance.

4. Decreased Fuel Efficiency
Have you noticed you’re filling up more often than usual? Dirty or low oil may be the culprit.
When your engine isn’t properly lubricated, it has to work harder — which burns more fuel. This drop in efficiency is often gradual, but it can become noticeable over time, especially if your driving habits haven’t changed.
Routine oil change service in Guelph helps keep your engine running smoothly and your fuel costs down.
5. A Burning Smell Inside the Cabin
This one’s never a good sign.
If you catch a burning smell while driving, especially something that smells like burning oil or plastic, pull over and check your oil levels. Oil that’s old or leaking can drip onto hot engine components and burn — which not only smells terrible but can cause permanent damage.
If this happens, don’t wait. Come in for auto repair in Guelph so we can find the source of the leak and stop further harm.
Why Staying on Top of Oil Changes Matters
Oil is the lifeblood of your engine. It lubricates, cools, cleans, and protects dozens of fast-moving parts every time you drive. When it breaks down, your engine starts wearing itself down from the inside out.
Regular oil changes help you:
- Avoid expensive repairs
- Improve fuel economy
- Reduce emissions
- Extend your vehicle’s lifespan
- Protect your engine on both short and long drives
Our Guelph mechanics have seen what happens when oil changes are delayed for too long — and it’s not pretty.
How Often Should You Change Your Oil?
Most vehicles need an oil change every 5,000 to 10,000 km, depending on the oil type and your driving habits. If you mostly do short trips or drive in heavy traffic, you might need oil changes more frequently.
At EuroMechanic – Brock Road Garage, we’ll check your oil level and condition and give you a personalized recommendation based on your vehicle and service history.
