Default Miracle cooling additive . . . ?

in the October issue of Hemming's Classic Car, page 18, comes announcement of a product from MPT Industries for adding to the cooling system to "make your car run cooler and smoother". Has a link to .

It claims to do this as "the formula removes hot spots or air pockets to decrease the coolant's temperature up to 20 degrees".

Anyone know anything about this? Anyone willing to test it out?

This would mean doing a before/after under close to identical conditions while accurately monitoring temperature.

The cost is $11.95.

I admit to being skeptical. The old line about "if it seems too good to be true. . . then it probably is" comes to mind.

But . . . if it was worth, say, 10 degrees of decrease under meaningful conditions that were a challenge for the modest Squarebird cooling system (referring to stock), $12 would be cheap.

Alot of guys in this forum have worked hard to improve cooling. 6 blade fans, electric fans, shrouds . . .

the only thing that ended up working for me was to ditch the original 1958 radiator and install a brand new replacement!

I tried one of the cooling additives and in all honestly I didn't notice much if any difference.

Install a fan shroud off a 1961-63 T-bird, makes all the difference.

Y'know, over history, the automotive industry tried a lot of products including alcohol. <--which worked well with water even though it has a LOWER boiling point.

I'm sure 'cost' has much to do with this but it dawned on me that light oil would satisfy all the requirements of a cooling system including; pump lubrication, anti-corrosion, HIGH boiling point, anti-freeze, etc.

For instance, chefs use cooking oils to spread heat, like for popping corn. Without oil, corn kernels burn. Other oils are used for frying (chicken, potatoes), like to the tune of 500-degrees F, before cooking oil boils or flashes, well above the tolerance of rubber hoses.

How would a light oil do as a coolant? We use oil for heat-treat quenching on parts that are cherry red hot. Certainly, a couple hundred degrees for 10W oil should work very well without creating ANY pressure because there is no steam. So, it ain't never boiling over. - Dave
