What about the lead and other dissolved metals that are in it from being run in an engine? Nevermind the Ph level has to be 12.4 or higher to be considered a non-hazardous material. The EPA told us not to dump it down the drain. Collect and recycle.
While ethylene glycol and propolyne glycol are hte base stocks, there's also a full range of other ingredients that make it harmfull to the environment if dumped. Even the label on bottle states that it's harmfull.
We collect and recycle at the shop I work at.
