iv got about 15 chainsaws most retain their fluids pretty well. I dont store them on a white sheet of paper so I cant say for sure but whenever they cause a big spill its because the cap isnt seated well because it got woodchips on it. One of my favorites is an 80s homelite and the cap seal is a hard material so if its not totally clean and tight itll leak. Thats the only one id like to seal because it mostly lives on the hood of my jeep. Alot of them the oil hose that comes out of the tank is barely pushed on the nipple without a clamp so im sure they seep when the hose gets old and hard. I much prefer tanks that have the caps on top so they cant leak
