Thread: show us your chainsaws

Yep, the good old rapeseed oil. Twice the price for half as good! One thing about using hydraulic saws under water is the water effectively lubricates the bar to a certain extent so you can get away with much less oil on the bar and chain. Rapeseed oil tends to pick up a lot more moisture from the outside too, hard on filters and if there's a leaky connection as soon as you make the tool cold water pressure if its higher than line pressure can get into the hoses...
