I use NAPA thread cutting oil... yes it sounds weird, but its not whats on the lable that counts, but how it works.
its a water soluble oil that mixes with the effluent and coats the inside of the tank and prevents stuff from sticking, IN ADDITION to lubricating the valves....
veggie oils set ON TOP of the effluent and can only lubricate what it sticks to... and most oils wont stick to a wet surface, so there is very little lubrication happening...
I have no idea about how this may affect the bacteria that helps break down the waste because we usually dump at least every two weeks, which isnt much time for the bacteria to work its magic anyway... AND, the cutting oil being water soluble, it doesnt ever cause a build up, emulsification or congealing in cold weather....
I pour in a pint about every 6-8 months or so, and it has worked well for me the past 6 or 7 years since I've been using it....
