A friend runs it in his car.

I really dont see the point or benefit and I would not use it in my own car.

Whilst yes it may have some positives, ultimately it has less heat transfer ability than water.

Hi PT, I use Hyper Lube Coolant additive, with similar chemistry as Evans products.
I use soft water I make for home use to fill my cooling system.

These types of products REDUCE Coolant Voltage to ZERO.

YES, I AGREE with Steve's "tech" of LESS HEAT TRANSFER, which is VERY GOOD for engine HP.

The MOST IMPORTANT item in a cooling system is WHEN the coolant boils.
Increase the coolant system pressure as do Cup Cars and you increase that boiling point.
The Evans type of products ALSO raise that boiling point.

It is not snake oil? No.

If you are not seeing sustained tracked time (high temp) is it worth it? In most people's opinion, no.

If you do make the change, follow their flush procedure.

Obviously there is a potential benefit from the fluid not boiling, so it could maintain some cooling at those high temperatures

But then if temperatures are getting so high in the first place. IMO that is a problem that needs addressed rather than a fluid that doesnt boil.

I have it and use it. I will say I do not think it has the same capacity of removing heat as water and water wetter. Now here is he rub, my car has an MID sleeved block and they recommend it since it will not flash to steam on the very hot sleeve, like water does. Even though it is not over heating or boiling over, water briefly flashes to steam and recondenses before leaving the block or so I was told. This means hot spots on your thin sleeves causing extra stresses. I also only use a 7psi cap. You do not need to add pressure for the Evans, as it boils at 375 F at atmospheric pressure. We had a head gasket let go and I opened the cap with nary a hiss. People thought I was nuts, but I knew my temps were only at 260. No where near 375. Try that with water, but call the medics first. I like it and seem to have my cooling sorted for now.

I will point out, something most will never think of, it is very flammable. Not a big deal, most fluids under the hood are. So a head gasket leaking onto a header could be bad.

Flammable....? er nope

Er yep!

The fire I heard about was a turbo car that lost a head gasket. I am sure a red hot manifold is well be beyond the flash point. Open flame will not light it, but red hot metal would.

Hi ALL, SURE Glycol will "flame" when heated by HOT Metal, then a local spark for the ignition.

The Evans coolant/Delco coolant is Glycol based.

MY Concern is about the Coolant System Voltage being reduced to ZERO if possible.
This happens when there is NO/LOW water in the cooling system.
Water Ions can also be neutralized as happens when Hyper Lube is induced into the coolant
The LACK of a current flowing through the engine/radiator will increase engine life.
