There’s a lot more to RV antifreeze and regular antifreeze than that. It is helpful to know when to use which one, and this article should help you get a better understanding of it.
Some antifreeze only keeps the freezing point lower, while ignoring the boiling point. These can never be used as car Antifreeze because the ones used for cars are not used to defrosting the car, it is used as a coolant.
Car antifreeze is a rather common sight; it’s the coolant that people replace after a certain amount of time. Usually once every couple of years. The base system is the same for all types of vehicle engines. Add a 50/50 mixture of antifreeze and water directly into the radiator valve and rev up the engine till the air is out.

It’s the wanderlust, the freedom of the open road. It’s not the destination, but the journey. It’s exploring the world. You don’t need a house because when you travel, you’re home. That’s RV LIFE. [links]
If you have a bottle of antifreeze of unknown age or you are among one of the RVers that capture drained antifreeze for reuse, how do you know if it still offers freeze protection? here
Every fall when the weather cools, you start hearing RVers talk about antifreeze. If you are new to RVing you may find yourself asking, what is the purpose of RV antifreeze, and do I need some?

Many mechanics claim that testing the pH level of antifreeze is an effective way of determining its condition. Some professional repair shops offer additives ostensibly intended to insure a proper pH in your antifreeze.
Here’s the pitch: water has a pH of 7.0 and antifreeze has a pH of 10.5, so a 50-50 mix has a pH of 8.75, and that’s too acidic to protect the cooling system, so the pH must be modified to something around 10 to protect the dissimilar metals in the modern cooling system. And, further, antifreeze must be frequently replaced to ensure proper pH.
Last, but certainly not least, is whether the antifreeze in your car offers adequate protection against freezing. You can test this.
The sole exception is when the manufacturer says to put something else into the antifreeze solution, as specified in either the owner’s manual or the factory shop manual, in order to address a specific coolant concern. Cadillac, for example, specified the addition of “coolant tablets” to antifreeze in pre-2000 Northstar engines to eliminate a porosity problem with the aluminum engine block casting that could lead to coolant leaks.
Antifreeze’s sweet scent and flavor will attract animals, causing them to consume the product unknowingly. This will be harmful to their bodies and can ultimately disrupt the ecosystem. more
There are many differences between the two types of antifreeze as RV antifreeze is meant for the plumbing system, while automotive antifreeze is meant for the engine coolant system. more
As a result, it is necessary to keep antifreeze away from children and animals in case of ingestion. here
RV antifreeze is designed to avoid evaporation and freezing. here
