Fleetguard Coolant EG vs. PG

If you mix them the freeze point can't be easily found.

Good point, the freeze point checking device has to be the right one for PG otherwise erroneous readings. The EG checker is the most common and will not give correct results. Otherwise I buy my PG Compleat coolant thru Cummins. I like the stuff and as recognized, won't kill the dog or cat but might give them a good dose of laxative.

The DCA should be monitored using test strips. Last time I bought them from Cummins I asked specifically whether they would test PG coolant and was told yes, so make sure to ask. If DCA needed, I have used both coolant filter charged ones and bottled DCA. I prefer the coolant filter cartrige, just seems to make more sense regarding mixing it with the coolant over a period of time rather than a "shot" approach.
