Motor Oil Change Services

We offer full motor oil services in Thornhill, ON to keep your vehicle running right. Regular oil changes are a must for engine health and longevity.


Full Synthetic Oil Change

Synthetic oil gives your engine extra protection. We use synthetic oils that handle extreme temperatures better than regular oil.


Synthetic oil comes with some real perks:


  • Longer change intervals
  • Better fuel efficiency
  • Cleaner engine
  • Improved protection during cold starts


This premium option is great for newer vehicles and those in tough conditions. It costs more up front, but you might save money over time with fewer changes and less engine wear.


We recommend synthetic oil for high-performance vehicles, cars in extreme weather, or if you tow heavy loads.


Synthetic Blend Oil Change

Synthetic Blend is the perfect middle ground between conventional and full synthetic options. This service combines the enhanced protection of synthetic oil with the affordability of conventional oil, making it ideal for drivers who want upgraded engine protection without premium pricing. 


Synthetic blend oil delivers superior high-temperature resistance and improved cold-weather performance, reducing engine wear during those harsh Thornhill winters when conventional oil becomes thick and sluggish. 


It's particularly beneficial if you frequently make short trips where your engine doesn't fully warm up, drive in stop-and-go traffic, or own a vehicle with moderate mileage. 


Unlike conventional oil that breaks down faster, our synthetic blend maintains its protective properties longer, potentially extending your oil change intervals slightly while providing better protection for your engine's vital components. 


Conventional Oil

Conventional oil is still a solid, budget-friendly choice for many cars. We've got a range of conventional oil weights to fit your engine.



Most conventional oils need changing every 3,000-5,000 km. It's a bit more often than synthetic, but the price per service is lower.

Our Oil Change Inspection Checklist

When you stop by our Thornhill center for an oil change, we do more than just swap out your oil. We run through a full inspection to keep your car running its best.



Here's what our technicians check every time:


Engine Oil System Check:


  • Drain all old oil
  • Replace oil filter
  • Add new oil to the right level
  • Look for leaks around the filter and drain plug


Fluid Level Inspection:


  • Brake fluid
  • Power steering fluid
  • Transmission fluid
  • Coolant/antifreeze
  • Windshield washer fluid


We also check a few other key things:


  • Tire pressure and tread
  • Air filter
  • Battery health
  • Wiper blades
  • All exterior lights


If your oil change warning light pops up, don't ignore it! That's your engine asking for fresh oil, and waiting could mean big trouble.


After the inspection, you'll get a report with our findings and any recommendations. We believe in keeping you in the loop.


We reset your oil life monitor so you'll know when to come back next.

How Fresh Oil Protects Your Engine

Fresh oil is like a shield for your engine. With clean oil, moving parts glide smoothly instead of grinding and causing damage.



But oil doesn't last forever. Heat, moisture, and daily driving break it down, letting in contaminants that can harm your engine if you don't change it out.


Fresh oil gives you:


  • Lubrication – Less friction between moving parts
  • Cooling – Pulls heat away from engine components
  • Cleaning – Carries off dirt and metal bits
  • Sealing – Helps keep compression where it belongs


Skip oil changes, and sludge starts to build up. That thick gunk blocks oil flow and can lead to overheating or even major engine failure.


At our Thornhill center, we always use oil that matches your car's needs. Our techs drain the old stuff, swap the filter, and make sure your engine's protected.

How Often Should You Change Engine Oil?

How often you need an oil change depends on your vehicle and how you drive. Most newer cars can go 8,000 to 12,000 kilometers between changes.



For Thornhill drivers, your owner's manual is the best place to check. It's tailored to your car.


If you drive in tough conditions, you might need oil changes more often. That includes:


  • Lots of short trips (under 10 km)
  • Very hot or cold weather
  • Stop-and-go traffic in the GTA
  • Towing heavy stuff
  • Dusty roads


Older cars usually need oil changes every 5,000 kilometers. Even if you don't hit the mileage, we suggest an oil change every 6 months. Oil breaks down over time, even if you barely use the car.


Regular oil changes are one of the simplest ways to keep your engine going strong. Fresh oil lubricates, reduces friction, and helps get rid of gunk.

What Is Viscosity Rating?

Viscosity rating tells you how thick or thin your oil is. That matters for how well it protects your engine at different temperatures.



What Does Your Oil Life Monitor Tell You?

Your oil life monitor keeps track of how your oil is holding up, but it doesn’t actually test the oil itself. Instead, it looks at engine revolutions, temperature, and driving habits to estimate when you’ll need a change.


We suggest paying attention to your monitor. When it drops to 15% or less, it’s time to book an appointment.


Remember, tough driving (like extreme weather or traffic jams) can wear out oil faster. The monitor might not catch everything.


The oil life percentage doesn’t tell you about viscosity, so knowing both helps you take better care of your vehicle.


How Do We Dispose Of Old Oil?

We stick to tough environmental protocols when getting rid of your vehicle's old oil. Used oil goes straight into special containers, so there's no chance of spills or nasty contamination.


We've teamed up with certified recycling facilities in Thornhill. That way, the oil gets processed the right way and harmful chemicals stay out of our water and soil.

Real Stories in Thornhill, ON

"The staff at MR automotive are very professional and honest. When Bobby told me my air conditioning would be a little more expensive to fix due to the previous owner crazy gluing all of the lines together - I was happy to understand the situation instead of just being presented with a huge bill to replace everything. This isn't the type of shop where you'll be told to replace things prematurely or without proper explanation and proof - which is quite hard to find these days!"

"MR Automotive is full of people who know their stuff but it's also great for people who aren't car-savvy (like me!) I trust Bobby & David to do a great job every time, they never sell me on anything I don't need, but make sure I at least understand what's going on. Thankful to have a mechanic I know and love."
