People use a shop vac to create suction so that they can, for example, change out an oil drain plug without having to drain the oil first. One filter gushes hydraulic oil on the lX2610 when it's change and people have suggested using the shop vac trick to minimize oil loss. Many videos show the vac hose fitting tightly in the fill port, but some say to leave a gap so that it's not real tight. Tight would create more suction, but 'might' suck up oil? I'm kinda thinking it won't, but wonder if anyone has any real world experience that would bear on the 'tight or not-so-tight question?
Thanks
