In this article we will tell you:

• what oil do you need to fill in BMW

• When you should change oil in gasoline and diesel engines of bmw

• How to change the oil in a BMW (consider the example of BMW e39)

BMW service manual says – oil change must be carried out every year, or once a year and a half (depending on the amount of  distance traveled)

When to change oil

• Gasoline engines – 15,000 kilometers (~ 9,000 miles)

• Diesel engines – 10,000 kilometers (~ 6,000 miles)

If the car is operated in harsh conditions, the oil should be changed 2 times more often.

• Gasoline engines – 7000-8000 kilometers (~ 4000-5000 miles)

• Diesel engines – 5,000 kilometers (~ 3,000 miles)

Oil and its viscosity

Oil classification by base type:

• Mineral

• Synthetic

• Semi-synthetic

Mineral oil loses its characteristics quickly, unable to protect the engine and ensure its normal operation.

However it does attract many drivers because of its cheap price

If you want your car to be serviceable, use only synthetic or semi-synthetic oils, the presence of special additives in them will extend the life of the engine.

The viscosity of engine oil is the parameter that is marked with the letters SAE on the package.

Viscosity is regulated by different types of scavengers and chemical additives.

Motor oil viscosity table.

The main criterion is the climate in which the car is operated.

Functions and main tasks of oil

Lubrication of moving parts to reduce friction between them

• Cooling

• Corrosion Prevention

• Removal of wear products

Use oil recommended by the car manufacturer.

The main thing is that the oil complies with ACEA class: A3 / B3 (CCMC-G5 / PD2) or API SJ / CD. This list includes a large number of manufacturers, updated every year and called Special Oil.

These oils are recommended by BMW AG.

If you do not trust anyone, you can order original oil from BMW. Original code 83 21 9 407 782. This is the code for a liter canister. For a complete oil change in the engine, 6.5-7.5 liters are needed. (depends on the engine).

In general we can use these types of oil:

• BMW 5W40 – original

• Motul 8100 X-Clean + 5w30

• Pennasol “Super Pace 5W-40”

• Bardal 5w40 XTS.

• Mobile Super 3000 5-40

• Shell Helix Ultra 5-40.

• Total 5W40 • Liqui-Moly 5W40

Oil change in the BMW e39

To change the oil we need:

1.Instruments:

36 mm socket

17 mm spanner

Flat screwdriver

2. Materials:

engine oil

oil filter

drain plug sealing washer

Engine Oil Capacity for BMW E39:

• 2.0 M52V20 – 6.5 liters
• 2.2 M54V22 – 6.5 liters
• 2.5 M52V25 – 6.5 liters
• 2.8 M52V28 – 6.5 liters
• 3.0 M54V30 – 6.5 liters
• 3.5 M62V35 – 7.0 liters
• 4.4 M62V44 – 7.5 liters

We proceed to the replacement process.

1.Lift and secure the front of the vehicle.

2.Start the engine, let it run for 2-3 minutes.

This is done in order to warm the oil, since warm oil is not so viscous, and therefore, when draining, it will be possible to remove more dirt and metal particles.

3.Loosen the oil filter housing cover with the 36 mm head.

This is done so that the oil in the filter and the oil cup flows into the oil pan, if you do not perform this operation, then with a high probability you will leave a liter of old oil in the engine.

4.Find a container for old oil and place it under the drain plug.

5.We unscrew the drain plug with a 17 mm wrench and wait until the oil drains completely

6.Replace the o-ring on the cork and to screw it in

7.Remove the oil filter

8.Check filter housing; if the old filter still remain  partially on it, then clean it; if you do not, you may damage the new one

9.Remove the oil filter housing cover O-ring with a flat screwdriver.

10.Lubricate with fresh engine oil and install the lower stem o-rings and the upper cap o-ring.

11.We clean the interior where was the filter with the old oil and insert a new filter

12.Install the oil filter housing cover and spin it.

13.And just now we fill in new engine oil

14. Check the level on the oil dipstick

The mark will show the maximum, even if a little more, then everything is fine

15.We start the engine for 5-10 minutes, after what we check the level on the dipstick, it should be in the middle between the minimum and maximum levels
