RV antifreeze for breaking-in motors?

I have a industrial electric motor re-manufacturer next door to me. I was wrongly delivered a package for them and took it over. Talking with the owner, he showed me around including their bench testing stations and break in/load tanks. They are using straight RV antifreeze in their break-in tanks.
While it makes sense as it would reduce heat, act as lubrication, and would not create corrosion.

Propylene glycol based antifreeze of the RV/Marine type has phosphate in it as a corrosion inhibitor... water needs to be added to the inhibitor to activate the phosphate.
So... I don't know about 'straight'...

Most of use never knew what Ronson lighter fluid was... did we? Well, it is commonly known as heptane. In small amounts it can also be used to break in brushes however it could become a fire hazard if it gets close to its ignition point.

I heard someone at the R4 broke in their motor in Diet Pepsi (or was it diet Coke??)

Back in the innocent days of deadly non EPA chemicals, I discovered a compound called carbon tetrachloride its compound was great for breaking in brushes and it did a great job Now its hard to obtain and very expensive. very toxic!

Clay,
I know elevator companies use carbon tetrachloride on their electric motors. We raced drag cars with a guy that worked for Dover and he would use it for many applications including I think comm drops. Dave Knapp used something similar I believe as well.

Is there any difference between RV and Car antifreeze?? I would think its the same...

Propylene Glycol (non-toxic)- Ethylene Glycol (toxic)

Has anyone ever tried or heard of this?

What type of motors were they breaking in? It would surprise me if they were DC brush motors.

Never heard that, Clay. Ronson Lighter Fluid (Ronsonol trade name) is shown on the Shell MSDS as being naphtha, which is what I was always told it was, not heptane.
Ronsonol Light Fluid MSDS
It's very likely heptane is a constiuent of naphtha, as it falls in the range of hydrocarbons commonly found in naphtha, which is actually a mixture of various hydrocarbons.
From Wikipedia:
"Naphtha normally refers to a number of flammable liquid mixtures of hydrocarbons, i.e. a component of natural gas condensate or a distillation product from petroleum, coal tar, or peat boiling in a certain range and containing certain hydrocarbons. It is a broad term covering among the lightest and most volatile fractions of the liquid hydrocarbons in petroleum. Naphtha is a colorless to reddish-brown volatile aromatic liquid, very similar to gasoline.
In Petroleum Refinery Engineering, full range naphtha is defined as the fraction of hydrocarbons in petroleum boiling between 30 °C and 200 °C. It consists of a complex mixture of hydrocarbon molecules generally having between 5 and 12 carbon atoms. It typically constitutes 15–30% of crude oil, by weight. Light naphtha is the fraction boiling between 30 °C and 90 °C and consists of molecules with 5–6 carbon atoms. Heavy naphtha boils between 90 °C and 200 °C and consists of molecules with 6–12 carbons."
n-Heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16.

RV and camper antifreeze is a non toxic liquid used in the fresh water system to prevent freezing in winter and is drained when the weather warms.
