we will discuss the benefits of using RV antifreeze in your car and dispel some of the myths about it. Stay safe this winter and keep your car running smoothly with RV antifreeze!

Can You Use Rv Antifreeze In A Car? Avoid using RV antifreeze in your car and reverse. There are many different antifreezes that are not identical! Antifreeze products contain 90 90% glycol as well as 10% added ingredients. Glycol is a type of carbohydrate that is which is the principal ingredient of protecting against freezing.

The other ingredients in antifreeze can include corrosion inhibitors, dyes, and water. The different manufacturers have their own secret recipe for the mix they use.

Yes! RV antifreeze will protect your car from freezing temperatures and has many benefits. Here are some of the benefits of using RV antifreeze in your car:

It is less expensive than automotive antifreeze

RV antifreeze contains more glycol which gives it a higher boiling point than automotive antifreeze. This means that it can better protect your engine from overheating.

What antifreeze should I use in my RV?


If you’re looking for the best antifreeze for your RV, then propylene glycol is the way to go. It won’t cause any harm to your plumbing or pipes, and it’s also non-toxic, making it safe for use around children and pets. Plus, propylene glycol is effective in both hot and cold weather, so you can use it all year round.


Ethylene glycol is another option for RV antifreeze, but it’s not as safe as propylene glycol. Ethylene glycol is toxic, so if there are any leaks or spills, it can be dangerous for people and animals. It’s also not as effective in cold weather, so it’s not the best choice for winter use.

Is RV antifreeze the same as auto antifreeze?

There is an important distinction between RV antifreeze and auto antifreeze. RV antifreeze is intended to be piped into the system for plumbing in an RV. It is thus non-toxic, just similar to marine antifreeze. However, auto antifreeze is a toxic substance and should not be employed in the engine of your boat.

RV antifreeze is also known as propylene glycol, and it can be found in most hardware stores. Auto antifreeze, on the other hand, is composed of ethylene glycol and will poison animals that drink it. So, if you’re looking for a non-toxic option to keep your pipes from freezing in your RV, go with propylene glycol!

Can I put RV antifreeze in my radiator?

This is a question that we hear quite often here at our shop. The short answer is yes, you can put RV antifreeze in your radiator. However, we recommend against it for a few reasons.

First, RV antifreeze is expensive. Second, it can be difficult to get all of the RV antifreeze out of your radiator before refilling it with water. Third, and most importantly, RV antifreeze does not protect your engine as well as regular engine coolant.

Engine coolant has corrosion inhibitors that help protect your engine from rust and corrosion. If you do choose to use RV antifreeze in your radiator, be sure to flush the system thoroughly before refilling it with fresh

Can you use auto antifreeze in RV?

Antifreeze from cars (ethylene glycol) should not be used in an RV’s holding tank . It should not be thrown down a drain or in the environment.

If you accidentally use it, flush the tank with large amounts of water. If possible, have a professional do it. Do not risk your health or the environment by using automotive antifreeze in your RV.

The best way to avoid problems is to buy an RV-specific product that is safe for holding tanks and won’t harm the environment if it’s accidentally dumped. Many of these products are available at campgrounds and RV dealerships.

Some examples are Camco’s Tasteless Antifreeze, Thetford’s Aqua-Kem Deodorant, and Valterra’s V22362 Blue Bowl Waste Digester & Holding Tank Deodorant. Be sure to read the labels carefully and follow the directions.

Is Caravan antifreeze the same as car antifreeze?

The answer to this question is both yes and no. Caravan antifreeze is a type of car antifreeze, but not all car antifrees are suitable for use in a caravan.

Caravan antifreeze usually has a higher concentration of glycol than car antifreeze, which makes it more effective at preventing freezing in lower temperatures. It’s important to check the label of your antifreeze before using it in your caravan to make sure it’s up to the task.

If you’re unsure whether or not your car antifreeze is suitable for use in a caravan, it’s always best to err on the side of caution and use caravan-specific antifreeze

What is the difference between RV antifreeze and auto antifreeze?

Again, there’s the difference between RV and auto antifreeze. RV antifreeze is intended to be in the system for plumbing in an RV. It is, therefore, non-toxic similar to marine antifreeze. Contrary to auto antifreeze, it is harmful and shouldn’t be employed in the engine of your boat.

Auto antifreeze, on the other hand, is for automotive engines. It will cause corrosion in your boat’s engine and should never be used.

There are also different types of auto antifreeze. The two most common are ethylene glycol and propylene glycol. Ethylene glycol is more toxic than propylene glycol, but it has a higher boiling point and freezes at a lower temperature.

Propylene glycol is less likely to cause damage if it leaks from the cooling system, but it doesn’t work as well in extremely cold weather. Ultimately, you’ll need to decide which type of antifreeze is right for your car based on where you live and how you use your vehicle.

Is RV antifreeze heavier than water?

A: Perhaps however, you should remember that antifreeze weighs more than water and will try to find the lowest level within the pipe. If the main drain pipe is set at a constant pitch, which many do you might notice antifreeze draining out of the main drain in the water, within a few minutes of adding it to the pool.

If this happens, don’t be alarmed. Simply open the valve at the lowest point of the main drain line and let the antifreeze drain out until water comes out. Close the valve once water is seen coming out of the line. You’ve now bled the line of any air pockets and are ready to fill your pool with antifreeze.

If you have an automatic pool cover, you’ll need to take special care when adding antifreeze to your pool. Be sure to check your owner’s manual for specific instructions on how to do this properly. In most cases, you’ll need to remove the float switch from the automatic cover’s housing and set it aside in a safe place.

Can I use any antifreeze in my car?

The answer is no. You should always consult your car’s owner’s manual to see what type of antifreeze the manufacturer recommends. Different types of antifreeze are not interchangeable, and using the wrong kind can damage your car’s engine. Make sure you know what you’re doing before you add any fluids to your car.

If you’re unsure about which antifreeze to use, ask a qualified mechanic or bring your car to a reputable service station. They’ll be able to help you figure out which antifreeze is best for your vehicle. In the meantime, stay safe on the roads this winter!

Can RV antifreeze be used as windshield washer fluid?

RV antifreeze shouldn’t be used for windshield washing fluid. One reason is that RV antifreeze has a pink hue and therefore, using it as washer fluid may cause it to discolor and darken your windows.

Additionally, while RV antifreeze may help to prevent your washer fluid from freezing in extremely cold temperatures, it can actually damage your car’s paint if used too frequently.

If you’re looking for a product that will help to keep your windshield clean and clear in all weather conditions, we recommend using a dedicated windshield washing fluid. These fluids are typically formulated with special surfactants and cleaners that won’t damage your car’s paint or cause any other issues. Thanks for reading! Drive safe!

Windshield washing fluid is designed to be mixed with water so that it can easily be sprayed onto your windshield without damaging the glass.

What’s the difference between antifreeze and windshield washer fluid?

Antifreeze, sometimes labeled antifreeze/coolant, keeps the engine from freezing in the winter and overheating in the summer. The windshield wiper fluid helps improve visibility during stormy or cold conditions by melting ice and cleansing the windshield.

 While both liquids are important for car care, they should never be used interchangeably.

If your car is low on either of these fluids, it’s important to top them off as soon as possible. You can usually find these fluids at any auto parts store. Be sure to check your owner’s manual to see what type of fluid is best for your car.


Yes, you can use RV antifreeze in a car. It is important to make sure that the product you are using is rated for the lowest temperature expected during your trip. Mixing different types of antifreeze can cause damage to your vehicle’s engine and cooling system.
