Time for a bit of oil

With Falcon developing a bit of a raspy growl when travelling in 1 direction i thought it was time i performed a bit of maintenance on the fleet and oiled the gears. Growler really needed the oil as it no longer growls now! The nickname will remain intact though. Unfortunately oiling Falcon doesn't seem to have solved its growl but it might just be a case of the oil needing to work its way in. Here is Growler on a post-oiling test, without the cover.
