Car Mechanic Simulator 2018 is one of the most realistic auto repair simulation games, where even something as routine as changing the oil requires attention to detail. It is easy for beginners to get confused in the interface or miss an important step, which leads to “breakdowns” of virtual cars. This article will help you figure out how to properly pour oil into the engine, avoid mistakes and save game money on unnecessary repairs.

Unlike real life, where the consequences of an incorrect oil change can result in a major overhaul, in the game you only risk your virtual reputation and time. However, even here there are nuances: from the choice type of oil (mineral, semi-synthetic, synthetic) before controlling it level after filling. We'll walk you through the process step by step, including hidden game mechanics that aren't discussed in the tutorial.

We will pay special attention hidden parameter "fill quality", which affects engine wear in the long term. Even experienced players often miss this point, focusing only on the visual level of oil in the pan.

Preparing for an oil change: tools and materials

Before you start pouring, make sure you have everything you need. B Car Mechanic Simulator 2018 tools are bought in the store (Shop → Tools), and consumables are in the section Consumables. Without the right equipment, you won't even be able to unscrew the pan plug.

Here minimum setwhich will be required:

  • 🔧 Wrench (size depends on car model, usually 17 mm or 19 mm)
  • 🛢️ Funnel (purchased at Shop → Consumables, costs ~$15)
  • 🧴 New oil (type and size depend on the engine - more on that below)
  • 🔩 Oil filter (necessarily new, even if the old one “looks fine”)
  • 🧽 Rags (for cleaning up spilled oil, affects the cleanliness of the workshop)

Important: in game You cannot use the same oil for different engines. For example, if you filled 5W-30 into the engine requiring 10W-40, this will lead to accelerated wear and tear after a few in-game days. Check the requirements in Car Info → Engine Specs.

📊 Which brand of oil do you use most often in CMS 2018?
Castrol
Mobil 1
Liqui Moly
Valvoline
Anything cheaper

Step 1: Draining the old oil - where to look for the plug and filter

Start with this lift the car on a lift (F → Lift Car). B CMS 2018 The pan and oil filter are always located at the bottom, but their position varies depending on the model. For example, in JDM cars (for example, Mazda RX-7) the filter may be hidden behind a protection that will have to be removed.

To find the pan plug:

  1. Point the camera at the car and search hex nut (usually the largest at the bottom of the engine).
  2. Hover your cursor - if it's a traffic jam, a hint will appear Unscrew oil plug.
  3. Hold LMBto unscrew. Be prepared: the oil will start leaking out immediately!

The filter is more complicated: it can be either on the bottom or on top of the engine. In some machines (for example, BMW M3 E36) the filter is located front of the cylinder block and closed with a plastic cover. Use Inspect Mode (Tab) to inspect the engine from all sides.

💡

If the oil does not drain or flows too slowly, check to see if the drain plug is clogged with dirt. The game simulates this - clean it with a brush (Shop → Tools → Brush) before adding new oil.

One of the most common questions from newbies: "What kind of oil should I fill in?" B Car Mechanic Simulator 2018 Each engine has its own requirements for viscosity and type of oil. If you fill in the wrong amount, the engine will overheat or wear out quickly.

Below is a table with recommendations for popular models in the game:

Car model Engine type Recommended oil Volume, l
Honda Civic (D16) 1.6L I4 5W-30 (synthetic) 3.7
BMW M3 (S50) 3.0L I6 10W-40 (semi-synthetic) 6.5
Ford Mustang (5.0L) V8 5W-20 (synthetic) 5.7
Mazda RX-7 (13B) Rotary 10W-30 (special for rotary engines) 4.0
Toyota Supra (2JZ) 3.0L I6 Turbo 15W-50 (synthetic) 6.3

Important: the game has "universal oil" (Universal Oil), but it is only suitable for simple motors (e.g. VW Golf 1.4). For sports or turbocharged engines, its use will lead to breakdown after 1-2 game days.

What happens if you mix different types of oil?

In CMS 2018, mixing oils with different viscosities results in the formation of "sludge" in the engine. After 3-5 game days a notification will appear Engine sludge detected, and you will have to flush the system with a special liquid (Engine Flush, costs ~$50).

Step 3: Installing a new filter - why you shouldn’t skip this step

Many players forget to change the oil filter, considering it unnecessary. In reality (and in the game) the old filter becomes clogged with dirt particles, which leads to:

  • ⚠️ Impaired oil circulation (the engine heats up faster).
  • ⚠️ Abrasive particles getting into the oil (accelerated wear).
  • ⚠️ Risk of “oil starvation” during a cold start.

To replace the filter:

  1. Find its location (see step 1).
  2. Hover your cursor and a tooltip should appear Remove oil filter.
  3. Unscrew the old filter (hold LMB).
  4. Take the new filter from inventory and install it in place (RMB → Install).

Tip: Before installing a new filter lubricate its rubber ring with oil (click RMB → Lubricate). This will prevent sticking and make the next replacement easier. In the game, this does not affect gameplay, but adds realism.

Step 4: Filling with oil - how not to spill or overfill

Now the most crucial moment is filling in new oil. B CMS 2018 this is done through oil filler neck, which is usually located on top of the valve cover. To find it:

  1. Open the hood (F → Open Hood).
  2. Look for the cover with the inscription Oil Cap or the oil canna icon.
  3. Remove the cover (LMB), then take the funnel from inventory and place it in the neck.

Filling process:

  1. Take the oil canister from inventory.
  2. Point at the funnel and a hint will appear Pour oil.
  3. Hold LMBto start pouring. Release the button to stop.

Key points:

  • 📉 Do not add all the oil at once! In the game (as in reality), you need to check the level with a dipstick (Dipstick) every 0.5–1 liter.
  • 🔄 If you overfilled, drain the excess through the tray plug (you will have to lift the car again).
  • 🕒 After pouring, wait 10-15 seconds (time is accelerated in the game) so that the oil flows into the pan.
💡

The optimal oil level on the dipstick is between the marks MIN and MAX. If the level is higher MAX, this will lead to increased pressure and the risk of damage to the seals.

Step 5: Checking the level and starting the engine - hidden nuances

After filling the oil, many players immediately close the hood and take the car for a test drive. This is a mistake! B Car Mechanic Simulator 2018 yes hidden mechanics of the "first launch", which affects engine wear.

What to do:

  1. Close the oil filler cap.
  2. Insert the dipstick (Dipstick) back and take it out again to check the level.
  3. Start the engine (F → Start Engine) and let it idle for 20-30 seconds.
  4. Turn off the engine and check the level again with the dipstick - it may fall because the oil has filled the filter and channels.

If, after starting, foam or emulsion is visible on the dipstick, this means that:

  • Water got into the oil (for example, if the car was left in the rain for a long time in the game). Solution: drain the oil, dry the pan with a hairdryer (Shop → Tools → Hair Dryer), fill in a new one.
  • Different types of oils were mixed. Solution: complete flushing of the system.
💡

To speed up level checking, use a hotkey Q (quick access to the dipstick) if the cursor is already hovering over the engine.

Common mistakes and how to avoid them

Even experienced players sometimes make mistakes when changing oil in CMS 2018. Here are the most common ones and ways to prevent them:

⚠️ Attention: If a notification appears in the game after changing the oil Oil pressure low, this means that you either did not add oil or forgot to tighten the sump plug. Do not ignore this message - the engine will fail after 1-2 in-game days!

Top 5 mistakes:

  1. Using the wrong oil.

    For example, fill 5W-20 into an old diesel (Mercedes OM617), who needs 15W-40. Consequence: accelerated wear of the turbine.

  2. Screwing the pan plug without a sealing washer.

    Puck in play (Crush Washer) can be purchased separately for $5. Without it, the plug will leak, and the oil will disappear within a few in-game hours.

  3. Ignoring the oil filter.

    If you do not change the filter, after 3-4 oil changes it will become clogged and the engine will begin to lose power (Engine power reduced by 15%).

  4. Oil overflow.

    B CMS 2018 overflow more than 0.5 l higher MAX leads to squeezing out seals and leaks.

  5. They forget to “reset” the service interval.

    After changing the oil, you need to reset the counter in the on-board computer (Car Info → Service Reset), otherwise the client will return the car with a claim.

To avoid these mistakes, always follow the checklist (see widget above) and use Inspect Mode (Tab) to inspect the engine for leaks after replacement.

FAQ: Frequently asked questions about changing oil in CMS 2018

Is it possible to use one oil for all cars?

No. In the game, as in reality, each engine requires a specific viscosity and type of oil. For example, Mazda RX-7 rotary engine needs special oil for rotary internal combustion engines, and diesel BMW M57 - in oil with a high alkaline number. Using universal oil (Universal Oil) is permissible only for simple gasoline engines with a volume of up to 1.8 liters.

What to do if the engine knocks after changing the oil?

Knocking noise after oil change CMS 2018 means one of the problems:

  1. You filled up the oil wrong viscosity (for example, 5W-20 instead of 15W-50 for racing engines).
  2. In the engine insufficient oil level (check with a dipstick).
  3. You forgot tighten the drain plug or filter.
  4. Got into the oil dirt or metal shavings (needs washing).

Solution: drain the oil, flush the system (Engine Flush), check all plugs and fill with the correct oil.

How to speed up the oil change process?

B Car Mechanic Simulator 2018 you can optimize the process:

  • Use pneumatic impact wrench (Shop → Tools → Impact Wrench) to unscrew the plug faster.
  • Buy oil pump (Oil Pump), which automatically pumps out oil without a lift.
  • Prepare all tools and consumables in advance quick access (keys 1–9).

With these improvements, replacement time is reduced from 5 to 2 minutes of game time.

Where can I get money for expensive oil at the beginning of the game?

At the beginning of the game you have few funds, and high-quality oil (for example, Mobil 1) costs $30–$50 per canister. Here's how to save:

  • Buy oil wholesale in the section Bulk Purchases (up to 20% discount).
  • Use "budget" brands (for example, Valvoline instead of Liqui Moly) for simple machines.
  • Complete oil change tasks for cheap cars (for example, VW Polo or Toyota Corolla) where mineral oil is required.
  • Sell empty cans (Empty Oil Canister) back to the store for $2–$3.
