Changing the Engine Oil and Filter on your BMW F650, F700, or F800 Twin-Cylinder Motorcycle
Besides tires, there is nothing more hotly debated on various motorcycle forums than engine oil. Personally, I ascribe to this thinking: "Having engine oil is better than having no engine oil. Having engine oil at the correct level is better than having engine oil that is too low or too high. Having the correct viscosity/rating is better than the incorrect viscosity/rating. Finally - Having clean oil is better than having dirty oil."
With that in mind, BMW currently recommends that the 650/700/800 twin-cylinder "F" motorcycles use a SAE 15W-50 API SJ/JASO MA2 type of oil.
Originally, BMW recommend a different weight of oil, but then released a bulletin in March of 2013 (71-04-2013 (005)) noting the switch. At the same time, all of the motorcycle owner's manuals received the updated specification. The SJ rating denotes the oil has been tested according to the American Chemistry Council Product Approval Code of Practice and may utilize the API Base Oil Interchange and Viscosity Grade Engine Testing Guidelines, while the JASO MA2 is the "Japanese Auto Service Organization's" rating for modern motorcycle engines where the wet clutch, gearbox, and engine used the same oil. JASO-MA2 rated oils do not contain friction modifiers which could cause our F-twin bike's clutch to slip. (Think of all the trivia contests you're going to win now!)
Note 1: The specific bike shown is a 2013 F800GS, but the oil/filter change should be applicable to all twin-cylinder F650, F700 and F800 bikes and models
Note 2: The tools and materials used are by personal choice and are not due to any affiliation with any brand
Note 3: Early model F-twins came with a 24mm bolt as the drain plug, most were (and should be) replaced with the style that uses a 10mm hex socket. That "new" drain plug BMW Part Number is: 11 13 7 708 604
Materials Required:
- 3.1 quarts of BMW (or equivalent) 15W-50 oil
- Oil Filter - BMW Part Number: 11 42 8 409 567
- Crush washer for drain plug - BMW Part Number: 11 41 7 652 949
Tools Required:
- Oil filter wrench that fits the oil filter above (sold at many online retailers and your favorite dealer)
- 10mm hex socket (or possibly 24 mm 6-point socket)
- Ratchet(s) that fits both of the above
- Torque wrench(es)
- Drain pan
- Paper towel, rags, or your least-favorite t-shirt
