What’S The Best Rv Antifreeze?

When it comes to keeping your RV in good shape during the winter, nothing is more important than using a quality RV antifreeze.

Not all antifreezes are created equal, though, so it can be tough to decide which one to buy.

In this blog post, we will discuss the different types of RV antifreeze and help you choose the best one for your needs!

What’S The Best Rv Antifreeze? There are many different types of RV antifreeze on the market, so it can be hard to decide which one is best for your needs.

Here are a few things to keep in mind when choosing an RV antifreeze:

  • The climate you live in
  • The type of RV you have
  • Your budget

If you live in a cold climate, it’s important to choose an RV antifreeze that will protect your plumbing from freezing.

If you have a lightweight RV, you’ll need to choose an antifreeze that won’t damage your plumbing.

And if you’re on a budget, there are some great options that won’t break the bank.

Do you leave antifreeze in boat engine?

Note: Sam likes to leave the engine block flushed, but empty in winter.

However, certain marine engine manufacturers suggest to fill the entire engine up with antifreeze from RV.

Always follow your engine’s maker’s advice.

If you have a boat with an inboard engine, you’ve probably wondered whether you should leave antifreeze in the engine during winter storage.

The answer to this question depends on the make of your engine. Some marine engine manufacturers suggest that you fill the entire engine block with antifreeze from your RV, while others recommend flushing the block but leaving it empty.

Always follow your engine’s maker’s advice to ensure optimal performance and longevity.

Its important to always follow your engines makers recommendations in order to maintain peak performance and prevent any issues down the road.

What antifreeze should I use in my RV?

You’ll need to consult your RV owner’s manual to find out what type of antifreeze is best for your model.

In general, though, most RVs can use either propylene glycol or ethylene glycol antifreeze.

Whichever type you choose, make sure it’s labeled as nontoxic so that it won’t harm your RV’s water lines or plumbing if there’s a leak.

To play it safe, many RV owners opt for propylene glycol-based antifreeze even though it costs a bit more than ethylene glycol-based products.

What is the difference between marine antifreeze and automotive antifreeze?

Marine antifreeze is safe and typically includes corrosion and rust inhibitors that help protect your engine in winter.

However the auto antifreeze was designed to serve as an antifreeze as well as a coolant for your car’s engine.

It is extremely harmful and damaging to the environment.

 If you accidentally put automotive antifreeze in your boat, flush the system immediately and replace the fluids.

The main difference between marine and automotive antifreeze is that marine antifreeze is safe for the environment while automotive antifreeze is not.

Marine antifreeze also typically includes corrosion and rust inhibitors, while automotive antifreeze does not.

If you accidentally put automotive antifreeze in your boat, flush the system immediately and replace the fluids.

Both types ofanti freezes are used to lower the freezing point of water to prevent it from freezing in cold weather conditions.

Automotive antifreezes usually have a bittering agent added to it to make it taste unpleasant so that people do not accidentally drink it, as it can be deadly if ingested.

Marine antifreezes typically do not have a bittering agent added to them.

The main difference between marine and automotive antifreeze is that marine antifreeze is safe for the environment while automotive antifreeze is not.

Where does antifreeze go in a boat?

The answer to this question may seem obvious to some, but there are actually a few different schools of thought on the matter.

Some people believe that antifreeze should be added to the engine’s cooling system, while others believe it should be added to the boat’s bilge.

And still others believe that you shouldn’t add antifreeze to a boat at all!

So, which is the correct answer? Unfortunately, there is no one-size-fits-all answer to this question.

The best way to determine where to add antifreeze to your particular boat is to consult your owner’s manual.

Every boat is different, and each one has its own specific requirements when it comes to adding antifreeze.

If you don’t have your owner’s manual handy, or if you’re still not sure where to add antifreeze to your boat, the best thing to do is to ask a qualified marine mechanic.

They will be able to help you figure out where the antifreeze needs to go in your particular boat.

And, of course, they can also answer any other questions you might have about maintaining your boat. So don’t hesitate to give them a call!

Can I use regular antifreeze to winterize my boat?

The coolant in engines can be toxic and should never be used in any way of winterizing a boat.

The proper way to winterize a boat is by using non-toxic RV antifreeze.

This can be found at most hardware stores.

Always follow the directions on the package when using RV antifreeze.

There are many ways to winterize a boat, but using regular antifreeze is not one of them.

When it comes to properly winterizing your boat, always err on the side of caution and use only products that are specifically designed for boats.

Non-toxic RV antifreeze may cost a bit more than regular antifreeze, but it’s worth it peace of mind knowing that you’re taking care of your boat the right way.

How do you winterize a boat motor without starting it?

The first step is to change the oil.

This will ensure that any water that may have gotten into the motor during the summer months is removed.

Next, you’ll want to add a fuel stabilizer to the gas tank.

This will help keep the fuel from breaking down and causing problems over the winter.

Finally, you’ll need to disconnect the battery so that it doesn’t drain while the boat is in storage.

Follow these steps and your boat motor will be winterized and ready for next spring!

Can you use RV and marine antifreeze in a car?

IS USING RV & MARINE OR POOL & SPA ANTIFREEZE HARMFUL IF I PUT IT IN MY CAR RADIATOR? Yes. SPLASH(r) RV & Marine or Pool & Spa antifreeze is not intended for heating or cooling functions.

If you use it in your car radiator, not only will it fail to protect your engine from freezing, but the high level of corrosion inhibitors could actually damage your engine.

So, while it might seem like a good idea in a pinch, using RV & Marine or Pool & Spa antifreeze in your car is not recommended.

How do you winterize a boat without antifreeze?

There are a few different ways that you can winterize your boat without antifreeze.

One way is to simply drain all of the water out of the boat’s engine and then run the engine for a few minutes to make sure that all of the water is gone.

Another way is to add some type of oil to the boat’s engine before winterizing it.

This will help lubricate the engine and protect it from freezing.

Finally, you can also use a product called engine fogging oil which will help protect your boat’s engine from corrosion during the winter months.

If you follow these steps, you should be able to winterize your boat without antifreeze and keep it in good condition for next year.

Should you use antifreeze with ethylene glycol on a boat?

Tips to Winterize Your Boat utilize ethylene glycol which is extremely toxic to humans in potable water systems.

The best method is to empty the lines and water tanks of any water.

 If you must use water, be sure to use distilled or de-ionized water and not tap water which contains minerals that will promote corrosion.

Water systems on boats are different than those in homes. In a home, water is pumped from the municipal supply into a holding tank and then gravity feeds the home’s plumbing system.

Boat water systems are pressurized by one or more pumps and the pressure is maintained by a accumulator tank.

This type of system can become contaminated with bacteria that thrive in the warm, moist environment of a boat’s bilge.

To prevent this, it is important to sanitize the system before storing your boat for winter.

One way to do this is to add an antifreeze solution to the system. This will protect the system from freezing and will also help to prevent corrosion.

Antifreeze solutions are available in both propylene glycol and ethylene glycol formulations.

Propylene glycol is considered to be non-toxic and is the preferred choice for boats. Ethylene glycol is toxic and should only be used if absolutely necessary.

If you do use an antifreeze solution, be sure to follow the manufacturer’s instructions carefully.

In most cases, you will need to add the solution to the water tank and then run the pumps until the entire system has been flushed with the antifreeze solution.

Is RV antifreeze the same as marine antifreeze?

Because RV antifreeze is the same chemical that is Marine antifreeze, they can be interchangeable.

The difference is in the concentration of the ethylene glycol.

Marine antifreeze is made to protect against freezing and overheating in salt water, while RV antifreeze is made for fresh water cooling systems.

In a pinch, you can use RV antifreeze in your boat’s engine, but it’s not ideal because it doesn’t have the same level of protection against corrosion.

So there you have it, marine and RV antifreeze are basically the same thing!

If you ever find yourself in a situation where you need to top off your boat’s cooling system with whatever is available, don’t worry – RV antifreeze will do the job just fine.


RV antifreeze is a critical component of any RV owner’s arsenal.

It helps to protect your RV from the cold weather and keep all its systems running smoothly.

But with so many different types of RV antifreeze on the market, it can be tough to know which one is right for you.

In this article, we’ve outlined the pros and cons of each type of RV antifreeze, as well as some tips on how to choose the right one for your needs.

So whether you’re looking for conventional green Antifreeze or an eco-friendly propane-powered option, we’ve got you covered.
