Engine oil is the essential lubricant that maintains low friction among engine moving parts and additionally cools the engine. It is important to understand the role of oil viscosity in engine longevity.

A cold engine needs the oil to be low viscosity (thin) in order to circulate it. Low viscosity oil has the ability to form a low-friction layer between cold engine components. As the engine and oil heat up, it is important that the oil remain viscous instead of thinning out and losing its ability to maintain the lubricating layer. Modern engine oils are engineered to operate in a wide range of temperatures. Additives are used in both petroleum based and synthetic oils to maintain relatively stable viscosity through a range of temperatures. 

Oils are designated with a standard scale of viscosity markers: low numbers such as 5W indicate low viscosity (thin) and high numbers such as 50W indicate high viscosity (thick). Modern multi-viscosity oils are designated with a high and a low range. For example, 5W-50 indicates an oil that is as thin as 5W when cold but remain thick like 50W when hot. 

For most of North America the climate is such that BMW's synthetic 5W-40 is adequate nearly year round. However, for certain climate regions (extremely hot or extremely cold) or for sustained high-speed driving (towing a trailer for example) it may be necessary to consider oil with a more specialized viscosity range. Consult your owner's manual for the multi-viscosity oil suited to your climate and vehicle use.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches. 

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you are working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability. 

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.

In this article, I'll go over the steps involved with replacing the engine oil and filter on the BMW M44, M52 and M54 engine. Be sure to work with a warm engine and have a drain pan with a capacity of at least 10 liters. You should replace your engine oil and filter every 5,000 miles. Changing your engine is one of the most frequent and basic tasks you will perform on your BMW Z3. Remember to use high quality oil that meets BMW specifications, (specifications can be found in your owner's manual) a high quality oil filter and keep yourself protected from engine oil. 


Run engine for 2-3 minutes to warm engine oil. Do not allow engine to get too hot.

Models with 4-cylinder engine:

Figure 2

Models with 4-cylinder engine - Using an oil filter socket and a 6ÂÂ" extension, loosen oil filter housing lid until you can see sealing O-ring (green arrow). This allows oil in filter housing and filter to drain into engine oil pan. If you do not do this first, you will leave about a liter of old engine oil behind. Raise and support front of vehicle. See our tech article on jacking up vehicle. Place drain pan centered below oil drain plug.

Models with 4-cylinder engine - Using a 17mm wrench, remove oil drain plug. Allow engine oil to drain until it stops dripping. Keep an eye on oil as it drains. The stream of oil will move and there is a chance it will miss the drain pan. Install oil drain plug with new sealing washer and torque to 25 Nm (18 ft-lb). Remove drain pan from below vehicle.

Then torque oil filter cover to 25 Nm (18 ft-lb). Fill engine with engine oil, while filling use dipstick to obtain correct level. Oil capacity 4-cylinder: 5.0 liters

Models with 4-cylinder engine - Start engine; confirm oil warning light goes out.

Then pull dipstick and recheck oil level. Oil level should be within area marked by green arrows. Check that there are no oil leaks, lower vehicle from jack stands and you are done.

Figure 10

Models with 6-cylinder engine - This photo shows what can happen when a low quality oil filter is used. The filter can collapse and fall apart inside oil filter housing. If your filter is bent like the one shown, inspect filter housing and filter cover for oil filter debris. A broken piece of filter will jam and crush the new filter when you tighten cover.
