Use whatever's in it. If you're putting in fresh fluid, use whatever you want. Power Steering, ATF, 5w-10... I used power steering fluid in mine, but ATF will be easier to see through the reservoir, to look at the level...

i used 10w-30 for my trim pump, disconnect the lines on the cyldiners and have a buddy with a bucket or something to drain it into, hit the switch and pump it out, also pump out some fresh oil thru lines before refilling just to flush it out
