Changing the oil on a BMW R1150GS.

I'm not the most mechanically minded person on earth, so if you need to follow this guide you're probably fucked.

To change the oil on a BMW R1150 GS you will need.

  1. A BMW 1150GS
  2. Oil, about three and a half litres worth.
  3. A new oil filter
  4. A 10mm socket and drive thing for socket.
  5. A bigish allen key. I dunno what size.
  6. An oil filter wrench. The filter is all up in the engine, you need this badboy to get it out and get the new one in.
Take your GS and put it on its centre stand on flat ground. If its not absolutely fucking pishing down outside take it for a wee spin first to warm it up. Warm oil drains better than cold oil.
Put some old newspaper down in case you make a cunt of things and spill oil all over the floor resulting in you slipping later and dropping your bike.

Loosen the four nuts that hold the sump guard on. These fuckers can get pretty badly seized so put some copper grease or something on them. If the rubber mounts break use mole grips or plumbers pliers to unscrew the bastards. 

You should now have the sump guard off and four nuts. Two longish ones from the front with big washers and two smaller ones with wee washers from the rear.

Remove the sump plug to drain the oil out into an appropriate receptical, this will take a few minutes so go and have a beer or a cup of tea or something. I spoke to occasional Mikeworld visitor Paul and his dog Dot for a few minutes.


Once all the oil has finished draining replace the sump plug. Put a new crush washer on it if some spare ones came with your oil filter, the spare crush washers are for you gearbox and final drive plugs. DO NOT OVER TIGHTEN YOUR SUMP PLUG. Remove the old oil filter. Mind, this will be full of oil that with pish out all over the shop so be careful. Make sure the rubber ring from the old filter comes out too. Use some oil to lube the ring on the new filter and use the oil filter wrench to install it. Just don't tighten it up too much. Again, more ballet dancer than sumo wrestler.

Pour your new oil in. I went for this semi synthetic 20w50 from Put three and a half litres in then start your bike. It might knock it's cunt in for the first few seconds before the new filter fills up and the oil gets around the engine. Turn the bike off. Once you're sure there's no leaks replace the sump guard remembering to grease the threads so you don't get seized nuts. Check the oil level glass. If its half full perfect, if not top it up a wee bit. Mind that from top to bottom the sight glass is about a quarter of  a litre so don't go mental.

You should now be back to a scene like this but with oil all over the place. You're bike will appreciate it though.



  1. Too funny. Made me laugh. I'm wondering how difficult a job you had based on all the cursing. Hehe

  2. Is all the bad language really necessary to change oil? Also, your procedure is flawed. Always pre-fill the new filter with oil prior to installation. You might be better off just riding rather than offering maintenance suggestions.

    1. I find the bad language helps. You're right about filling the filter with oil, but thats a bit beyond my skillz.

  3. Brilliant. You always make me chuckle.

    And some days, I do think cursing is needed to change the oil. Most definitely.

  4. I was pissin myself reading this, you sure do have a way with words mike.

  5. I too thought I was fucked when that cunt of mine had crash bars to decuntify that fucker. I bitch fucked that cuntbag whore till the fucker slather fuck cunt slut. Then I damn fuck cock sucker clit faced whore. It's just that easy. Thanks for the pictures too.
