I'm impressed

I think someday most cars will call for it, if not all. That is of course, if the internal combustion engine survives.

Tom,
No old Buicks get 10W-30 in the winter and 20W-50 in the summer.

New car is a turbo but I think the others get spec'ed for synthetic oil too. I think they're doing it to get the highest "mpg" numbers on the window sticker and elsewhere. With the government requiring higher mileage .........

Capthead,
I kinda liked the Prius but you can't get one that's not a hybrid. No V8s either.

A thought just occurred to me. Would my 73 Buick do well on 5W-30 mobile 1 synthetic? Could use more gas mileage on that one!

Coolant disposal/recycle

Any suggestions for the disposal/recycle of used coolant?

Check with your town...some allow you to pour it down the drain...

Some auto repair and marinas recycle it..but often just the glycol based ones.

Recyling - ask at your local garage. They have to deal with it regularily.
My garage does nick me something for it as it costs him. The oil he takes for free.

What about your marina?

One thing I don't understand is this relatively new idea of 'pre-mixed coolant'. It sounds to me like they are diluting the original product (with water I suppose) and selling me a diluted product?? ....so I have to buy twice as much to get the full benefit??
Can't I simply dilute my own 'full strength' product?

Brian, sure you can and as others have pointed out, around 65% solution will give the lowest freeze point. However, the specific heat capacity gets worse the greater by volume of coolant. Here is a good explanation in layman terms (even I could understand it) of how it all works.

Things you should know about coolant – hellafunctional

The auto parts store I called would not take it but my county has several disposal sites and some of them will accept used coolant. So check with your city or county.

Walmart told me they would accept it over the phone but when I got there they weren't sure. After some complaining on my part they agreed to take it and dumped it in with the used oil. I don't think they were supposed to do that.

This reminds me, I still have five gallons in a jug, waiting for me to get rid of it.

Greeting: I rarely get angry or upset, but when dealing with anti-freeze products containing Ethylene glycol being dumped in to any drain which leads in to fresh or salt water, the person doing so should be "shot". A cup full will distroy the life in a ten to twenty acre pond. Please recycle do not discharge it into a CT drain. Enough said, Bill

Greetings,
Mr. C. I hear ya' loud and clear. Either municipalities don't know or care (they should) about what gets recycled. One of MY beefs is quite simple. Nobody around here will accept used flashlight type batteries. Into the trash then to land fill then into the environment/water table.
Now back to coolants/fluids....

That must be a mighty shallow pond as the LC50 dose for fish is 17800mg/liter.

Sounds shaky for toxic amount though I would never just indiscriminately dump....plus the treatment plants supposedly take care of the the antifreeze toxicity...otherwise they wouldn't approve of it (either in just reduced concentrations or what they add before it's released).

Before getting all upset about a little antifreeze...there's plenty more to worry about in the environment.

I'll be sure to report the EG spill to the EPA when my airplane de-ices on my next flight.

What about the toxicity of Ethylene Glycol?

“The City has not performed analysis for Ethylene Glycol, per se, at the treatment plant inflow. However, ethylene glycol, while toxic at high concentration, is highly treatable at the concentrations received by a wastewater treatment plant. It is broken down by the biological processes just like all of the other organic compounds received for treatment. Of course, the discharge of “significant quantities” (hundreds of gallons) of relatively concentrated ethylene glycol could result in a toxic condition being created at our treatment plant. However, it’s highly unlikely that service shops will ever release such volumes.”

Hmmmm. Perhaps my sarcasm was not detected.

EG will poison your kitty and your kiddie when ingested due to its sweet taste. One cup will not likely poison the daphnia or trout when placed in a bucket, let a twenty acre pond.

Sorry Cyclone Bill. No offense, but hyperbole makes my otherwise inert passive aggressive nature kick in.

I'd rather you shot me for s character flaw than some poor sap spilling EG. (Please note my use of hyperbole in that last sentence.)
