I cannot decide on a coolant to use with an Accu-lube setup. I will do mainly aluminum and steel milling.
They recommend the LB2000, but I see a lot of complaints about it being gummy and messy.
They recommended LBSYNT01 as a synthetic alternative, but my searches don't produce much info or opinions on this.

I have seen some people recommend the Trico MD-7. At this point from what I can find searching, this is the only one I see good reviews for.

I am looking for more opinions. This is a micro-drop system, so I am only interested in coolants for this type of system.

Thanks
