Buyer’s Guide for Buying the Best RV Antifreeze
In this section, you will learn about the important features to look for before buying an RV antifreeze for winterization. We also added some easy tips that will assist you in selecting the best RV antifreeze. There is also a short how-to video on installing the RV antifreeze.
Antifreeze Depending on Price and Amount
The best budget RV antifreeze we mention in our article comes at a price of $19.25. Normally, the cheaper RV antifreezes are priced between $15-$20. The PEAK RV & Marine Antifreeze is a great selection for such a price and it is also a high-quality RV antifreeze.
Depending upon the amount of antifreeze the price will increase. But it is more economical to buy in a large amount as the cost is less if you consider per gallon price. Also, a 1-gallon antifreeze pack is hardly enough for winterizing a large RV. We have Camco Easy Going RV and Marine Antifreeze that comes in a 6 x 1-gallon pack, enough for winterization.
Also the price increases with added extra features like slush protection, pre-dilution, and safety grades, like the safest RV antifreeze in our article, BioTherm Fluids RV Antifreeze. As safety is always the number one priority, paying a little more to be safe is always recommended.
Dilution and Concentration
RV antifreeze comes in two forms: pre-diluted, and concentrated antifreeze. Concentrated ones require mixing in water before use, but they are less expensive than pre-diluted ones. Pre-diluted RV antifreeze is ready to be used in your RV’s plumbing system.
But keep in mind that for concentrated RV antifreeze if you mistakenly mix more water than indicated, then the temperature rating can be reduced and can damage your RV in winter. So, you have to be precise in mixing in exchange for the price advantage.
Chemical Formula
The formulation of antifreeze is important in selecting the best non-toxic and non-corrosive RV antifreeze. Usually, RV antifreeze uses additives like methanol or isopropanol to prevent the water in the plumbing system from freezing. All modern antifreeze is mostly FDA approved and environmentally safe. But older antifreeze products are usually more deleterious as they are ethanol-based.
Some antifreeze additives like phosphates may induce corrosion and rust in your piping system. So, it is recommended to avoid such products.
An RV antifreeze can be easily spilled and flushed into the environment. Thus, it is always encouraged to buy a biodegradable RV antifreeze as it is safe for your RV and any other living beings around you. We recommend buying BioTherm Fluids RV Antifreeze as it is the safest and most environment-friendly RV antifreeze out there.
Temperature Rating
Temperature rating is an important factor in considering the RV antifreeze brand. As an example, the record winter temperature in Maine is -48°F. So, an RV antifreeze with a -50°F temperature rating is enough for pipe protection.
However, some states, like Alaska, have colder winters. So we recommend using Century Chemical TF1 Transfer Fluid in such cold regions, as this RV antifreeze has a temperature rating of -100°F.
Applicability and Usage
Most of the RV antifreezes are not just specially made for RVs, but rather they can be used in marine systems and all-terrain vehicles as well. As an antifreeze works the same in both plumbing systems and engine cooling systems, you can use the same product in both.
The most versatile product we reviewed in our article is SPLASH RV & Marine Antifreeze, which is famous for its wide application of use.
Different Varieties of RV Antifreeze
Usually, you can find three types of RV antifreeze depending on the main chemical composition. The propylene based is the most popular and ethanol-based are the oldest. The mixed blend of both is rare in the case of RV antifreeze.
Most modern RV antifreeze is propylene-based as propylene glycol is less toxic and environmentally safe. The US FDA approves propylene-based RV antifreeze as they are safe to use in drinking water systems. They are also better lubricants for your piping system. This chemical is also common in processed foods.
Ethylene glycol antifreezes are sometimes seen in older automobile brands as they have higher boiling points and a great temperature rating. But they are not safe for use in a drinking water system. But ethanol-based antifreeze is less expensive and more widely available than propylene-based RV antifreeze.
Difference between normal and RV antifreeze and why do you need it?
There is a lot of difference between a normal antifreeze and an RV antifreeze. Normal antifreeze is mostly ethanol-based and is used for engine cooling systems. They are toxic and dangerous if consumed. But RV antifreeze is generally FDA-approved and safe to use in drinking water plumbing systems. So always check if you are buying the right antifreeze.
Also, RV antifreeze is an absolute must if the temperature falls below freezing during the winter season in your region. As the temperature reaches below freezing, the moisture and water in the pipes will freeze and cause pressure to build-up, which afterward creates fractures in pipes.
RV antifreeze is a chemically compound additive that will decrease the freezing temperature of the water in RV pipes. This prevents the water from freezing and keeps the pipes from fracturing. So, for winterization, you cannot do without an RV antifreeze.
How to Install Antifreeze in an RV
