My 12GS as of 2 weeks ago has now started to use oil at a much faster rate than it did before I had a new rocker cover fitted – I also started using 20w50 oil rather than 10w40 a few days before I needed a new rocker cover… so not sure if it’s one, or other, or both (or neither!) that might be to blame… anyone have any suggestions?
Scenario is as follows:
Bike got pushed over while I was away for the weekend – bike was on its side for probably 12 hours or more before I could get back to pick it up, the right hand rocker cover cracked near the corner bolt, and all the oil leaked out. Had it recovered to my friendly BMW dealer, who checked it over, fixed the rocker cover, and gave it the all clear. The oil that was used for the refill was Castrol Actevo 20w/50. Up until one week before I had been running Castrol 10w40, but used 20w50 for a refill the week before, and had 20w50 put in when they did the rocker cover repair (since that’s what BMW are now recommending…).
Pick up bike, oil level glass completely full as expected. One week later, routine check, and I was very surprised to find that the glass was now indicating that the oil level was now over 2/3 empty. Usual usage, daily commute of about 10 miles through typical London traffic. One longer run at the weekend to see some friends on the edge of town. Not a massive run out. Mdae a mental note to keep a closer eye than usual on oil usage, I topped it up to over ¾ full on the glass on Monday morning, usual commute usage during the week, one long run up to Cambridgeshire on Friday to leave bike in friend’s garage while I’m away for a couple of weeks - and was surprised to find that the oil level is now down to absolute minimum again. It’s drinking the stuff, t’would seem.
There are no outward signs of anything up anywhere i.e. leakage, smoke from exhaust etc. Bike seems to be running absolutely fine. And I can’t believe that it’s down to using 20w50 rather than 10w40 so I figure it must relate to the rocker cover repair, but can’t figure out why that should make a difference?
Anyone got any ideas...?
