You only oil the ones in the middle that all connect to each other! If you look up poptropica cheats and walk throughs for wild west island, there is a video and it shows which ones to oil too.
The mill gears on Astro Knights Island are in the second-floor loft of the mill, and they are locked to prevent the windmill arms from turning. Grab the short hanging rope to unlock the gears. Go outside and turn the windmill arms counter-clockwise by climbing on them, and you will see the roof dome open.
To unlock the gears in the mill you have to jump on the haystack,then the giant gray thingamajigs, then to the wood thing with hay on it,then jump on the rope and the mill gears should be unlocked. GOOD LUCK!
you first have to get the oil can. Then oil the middle row and the gears will turn
you don't move the mill for the guy. go inside. jump up the boards until you get to the top (you can see the gears). jump on top of the huge gears to get to the rope that is just hanging there. pull it. get out and turn the mill be jumping on it. the hatch on top will just open the more you turn it. Turn it counter clockwise so it will work. (To the left side.) Go inside to power the hovering thing with manure
Make a trail of oil to the big gears
To get to the hovercraft in the attic of the mill, pull the rope to unlock the gears. Then go outside and turn the windmill arms by jumping on them. When they turn counterclockwise, the roof dome will open. Add manure to the hovercraft and it will go to the swamp.
they turn and make movement
You have to get on the sign on the side then jump on on of the hands of the mill and make it turn counter clockwise,then the top of the mill will open and you go in.
with windmills which gears turn a generator to make electricity
Go inside the mill, on the second floor, and hang from the rope that unlocks the mill gears. Then go outside and climb on the windmill arms to turn them counter-clockwise. This will open the roof dome. (see related question)
Go inside the mill (Ye Olde Rumour Mille) and up into the loft. Hang from the rope to release the gear lock on the windmill arms. Turn them counterclockwise to open the mill dome.
you have to stand on the mill and you have to make it go left and up the top is a little hole thing when it comes open quickly go in it
