I still remember the first time I tried to figure out how to drain oil in Car Mechanic Simulator 2015. I was excited. Nervous. Maybe even a little overconfident.

If you’ve just started playing Car Mechanic Simulator 2015 (CMS 2015), you’re probably getting that same mix of excitement and confusion. Trust me, it’s normal. It might feel like you’re actually working under the hood of a real car. That’s the charm of CMS 2015. But like in real life, oil changes can get messy—unless you know the steps.
This article will walk you through how to drain oil in Car Mechanic Simulator 2015 like a pro. It’s not just a dry list of instructions. It’s packed with friendly advice, useful tables, personal insights, and SEO-friendly tips to help you truly master this simple but essential task in the game.
So, if you’re stuck on your first job or just want to clean up your workflow, buckle up. You’re about to learn the right way to drain engine oil in CMS 2015.
Why Draining Oil Matters in CMS 2015

Much like in real life, engine oil is the lifeblood of the vehicle. Without clean oil, the engine doesn’t run efficiently. In Car Mechanic Simulator 2015, the same logic applies. If you try to install new parts or complete certain jobs without draining the oil first, the game will call you out. You might even lose money by damaging parts or getting lower job satisfaction ratings.
Here’s why oil changes are a big deal in the game:
-
Mission completion: Many repair jobs require an oil change.
-
Avoid penalties: Draining oil improperly causes job errors.
-
Simulation realism: The game simulates real-life mechanic processes.
-
Engine health: New oil = better engine performance.
And believe it or not, even though it’s a game, it feels really rewarding when you do it right. There’s something calming about getting your hands “dirty” without actually getting dirty.
Let’s break it down step-by-step.
Tools You’ll Need to Drain Oil in CMS 2015
Before you touch a car, you need the right tools. Just like a real garage, Car Mechanic Simulator 2015 requires proper equipment.
Here’s a quick list:
-
Oil Drain Tool (You can buy it in the Tools section)
-
Car Lift (Most cars must be raised for oil drainage)
-
Access to the Garage Work Area
Pro Tip: If you try to drain oil without a lift or oil drain tool, it just won’t work. And yes, I’ve made that mistake more times than I care to admit!
Here’s a quick table of essentials:
Tool / Item | Purpose | Where to Get It |
---|---|---|
Oil Drain Machine | Collects old oil | Buy from Tools tab |
Car Lift | Raises vehicle for underbody access | Already in garage (use arrow) |
Engine Info Panel | Shows oil condition and level | In Inspection Mode |
These tools are your best friends for any job involving fluids in CMS 2015.
Step 1: Set the Car on the Lift
Let’s get to the juicy part—how to drain oil in Car Mechanic Simulator 2015.
Once you’ve accepted a job that involves an oil change, the first thing you’ll want to do is bring the car to the lift.
Here’s how:
-
Click on the car in the garage.
-
Select “Move Car”.
-
Choose “Car Lift A” or “Car Lift B”.
Boom. The car moves to the lift like magic.
Now hit the lift button to raise the car. You’ll want it high enough to access the oil pan from underneath. If you’ve ever worked on a real car, you know how awkward it is to crawl under one. CMS makes that part easier—but only if you raise the car correctly.
Why this matters: You can’t access the oil drain plug unless the car is up in the air. You’d be surprised how many players forget this step and think the game is bugged.
Step 2: Position the Oil Drain Under the Vehicle
Okay, car’s in the air. Now it’s time to grab your oil drain tool.
-
Go to your tools inventory.
-
Find the oil drain (a red and silver rolling canister).
-
Click on it and select “Move Equipment”.
-
Move it to Car Lift A (or B, depending on your setup).
Once it’s there, click on the oil drain again and choose “Use Equipment.” If it’s positioned correctly under the oil pan, the oil will begin to drain.
It’s oddly satisfying to watch the dark liquid flow out. It’s a bit like cooking when the sauce hits just the right consistency—something about it just feels good.
Important Tip: If the oil drain isn’t placed correctly, the option to drain oil won’t appear. It can be frustrating, but don’t force it—just reposition it carefully.
Step 3: Remove the Oil Filter (Optional but Recommended)
So you’ve drained the oil. Great! But if you want to do a complete oil change in CMS 2015, you’ll also want to remove the old oil filter.
Here’s how:
-
Switch to Disassembly Mode (hold right mouse button).
-
Look under the car for the oil filter (usually a small, round part attached to the engine block).
-
Click on it and remove it.
Replacing the filter isn’t always required for every job, but it’s a good habit. Think of it like changing your socks after a long run. You could skip it, but do you really want to?
Once removed, don’t forget to add a new filter before refilling the oil. The game will penalize you if you forget. And yes—I’ve learned that one the hard way, too!
Step 4: Lower the Car and Refill the Oil
After the oil is drained and the filter is replaced, it’s time to lower the car.
-
Use the car lift button to bring the vehicle back down.
-
Click on the engine cover to remove it (if needed).
-
Locate the oil fill cap on top of the engine.
-
Click it and choose “Add Oil.”
Pour the oil in slowly and watch the dipstick level carefully. Overfilling is just as bad as underfilling. CMS 2015 doesn’t let you eyeball it, so keep checking the oil level gauge.
Quick Tip: Use the dipstick after every few seconds of pouring. When it hits the full line—stop.
I’ve gone past the line a few times, and trust me, spilling oil isn’t fun—even in a game.
Common Mistakes Players Make When Draining Oil in CMS 2015
Even the most experienced players slip up once in a while. So if you’ve already messed up a few oil jobs—don’t worry, you’re not alone. Here are the most common goofs people make when learning how to drain oil in Car Mechanic Simulator 2015.
1. Forgetting the Oil Drain Tool
This is the number one blunder. A player raises the car, clicks all over the engine, and nothing happens. Why? They never brought the oil drain machine to the vehicle. It’s like trying to cook pasta without boiling water. Always grab the tool first.
2. Not Raising the Car Fully
You need the vehicle to be fully lifted to access the oil pan underneath. Halfway won’t cut it. The drain plug area stays grayed out if the car’s not high enough.
3. Skipping the Oil Filter
Some jobs require it, some don’t. But changing the oil filter is always good practice. Think of it like cleaning your blender before making a new smoothie—you could skip it, but the results won’t be great.
4. Overfilling the Engine
This one hits hard. You pour in the oil too fast, don’t check the dipstick, and boom—you’ve overfilled. Now the engine’s performance might suffer. The game isn’t forgiving about it either.
5. Not Completing the Job Checklist
CMS 2015 uses a job checklist system. If oil change is listed and you forget even one part—like the filter—you’ll fail the task. Always double-check that every step is done before hitting that finish button.
Speed Tips: How to Change Oil Fast and Efficiently
Once you get the hang of it, oil changes in CMS 2015 can be lightning quick. I’m talking two to three minutes, tops. Here’s how to shave seconds off each task:
-
Memorize tool locations so you don’t waste time scrolling
-
Always use hotkeys to switch between disassembly and assembly mode
-
Position the oil drain machine before lifting the car
-
Use the mouse wheel to zoom in and click precisely
-
Replace the oil filter while the oil drains to multitask
The game rewards speed and accuracy. Fast oil jobs mean more completed contracts, which leads to better XP and more cash in your virtual wallet. And let’s be real—there’s something satisfying about doing it with clean execution.
Real-Life Parallels: What CMS 2015 Teaches You About Car Maintenance
Let me tell you something funny. I had never changed real engine oil in my life until after I mastered how to drain oil in Car Mechanic Simulator 2015. When I finally did it on my old Honda Civic, it felt weirdly familiar. That’s how realistic this game can be.
Here’s what CMS 2015 teaches you that translates to the real world:
-
Oil is critical for engine health—both virtually and in reality
-
You need the right tools to do the job
-
Skipping steps causes damage or job failure
-
You should always double-check your work
-
Clean workspaces matter, even in virtual garages
CMS 2015 might be a game, but it builds muscle memory and mechanical logic. I’ve met real mechanics who recommend it to beginners because it builds intuition—even if you’re just clicking a mouse.
How Oil Changes Affect Your Progress in CMS 2015
You might think oil changes are just filler tasks in the game. But actually, they’re key to leveling up faster. Here’s why:
-
Early missions often include oil changes
-
Completing them accurately boosts your job rating
-
High ratings mean more reputation points
-
Reputation points unlock bigger jobs
-
Bigger jobs = more money + XP
Basically, the better you get at oil jobs, the faster you grow in the game. It’s one of those low-risk, high-reward systems. Nail the basics, and you’ll open doors to engine rebuilds, gearbox jobs, and full restorations later.
Don’t skip or rush through oil jobs—they lay the foundation for everything else.
