How to Oil Service a BMW R850R
1. Place your R850R on the center stand and turn on the engine. Let the engine idle for five to 10 minutes. This allows the oil to warm up and flow out of the engine more quickly.
2. Shut off the engine. Position the oil drain pan underneath the motorcycle's engine. Remove the oil drain plug from the oil pan with an 8 mm Allen wrench.
3. Drain the oil out of the engine and into the pan.
4. Remove the oil filter next to the oil pan, using the oil filter wrench. Drop the old filter into the drain pan. Attach the new filter.
5. Reinstall the oil drain plug and tighten it using the 8 mm Allen wrench.
6. Open the oil filler cap located at the top of the R850R. Slowly pour in 3.75 quarts of fresh oil. Reattach the oil filler cap.
7. Remove the BMW R850R from the center stand and turn on the engine again. Allow it to idle for a few minutes so that the new oil will circulate throughout the engine.
8. Turn off the engine and allow your BMW motorcycle to sit for several hours. Check the oil indicator sight glass near the engine oil pan to ensure that the oil level is at the minimum level. Add more oil as needed.
