I only have a 6" trim saw. Instructions say that water alone is OK but water with some additive (cooling) is even better.
Which additive do you all recommend. I want something concentrated which can be diluted for use as I don't want to have gallons of the stuff around. No room.
Thanks in advance.

I am on an additive search as well, or more accurately a new additive. I don't know if it's the hard more alkaline water here, or a change in the additive, but the Johnson Bros additive I have used for years now froths.

“You preachers of equality, the tyrannomania of impotence clamors thus out of you for equality: your most secret ambitions to be tyrants thus shroud themselves in words of virtue. Aggrieved conceit, repressed envy—perhaps the conceit and envy of your fathers—erupt from you as a flame and as the frenzy of revenge.”
—Friedrich Nietzsche

I use Finish Jet-Dry. It'surfactant action decreases water tension, which enables increased contact between water and other surfaces. That closer contact enhances heat transfer. It’s readily available and it takes just a couple of drops in a water-based trim saw.

I've heard of using wetting agents, imagine just straight borax might do it.
In my case I don't want to drain the saw, so rust inhibitors are also important.
After this years trip north I want to finish the trim saw with the dry sump and water pump so the blade won't be submerged when not cutting.

I use Tool Cool water-soluble synthetic lube / coolant from the Rock Shed. $8 / 8 oz ain't cheap but i don't cut very much and it seems to work ok. No rust issues on my blade ever (pan is cast aluminum). Plus i like having an excuse to cruise over to Keystone a couple times each summer.

EDIT: Oh yeah, mix is 10:1 for cutting so 8oz doesn't go very far.
