I am manually reverting to undo deletes on 09:17, 14 September 2013 and 09:16, 14 September 2013. edits by IP 125.99.118.188. The first edit removed info arguably overly-specific info on graphite lube, however the second edit removed general context necessary to understand the article as a whole. Dear 125.99.118.188, if you have a good reason then please discuss it here. Thanks! --72.37.171.20 (talk) 19:21, 9 October 2013 (UTC)[reply]
