Buyer’s Guide to Buying the Best RV Antifreeze
When it comes to picking out the best RV antifreeze, there are a few key factors you need to consider to ensure you’re getting the most bang for your buck. Here’s a friendly guide based on my own experiences and some solid advice from the RV community.
Price
RV antifreeze prices are fairly consistent. Generally, a gallon jug of propylene glycol-based antifreeze starts around $15-$20. If you’re like me and love a good deal, buying in bulk can save you quite a bit. Typically, purchasing five gallons or more reduces the cost per gallon significantly.
Dilution and Concentration
The choice between pre-diluted and concentrated antifreeze often boils down to convenience and cost. Pre-diluted antifreeze is ready to use right out of the jug, which is super convenient. This is great if you don’t want to mess around with mixing ratios, especially if you’re not confident about getting it just right. However, it does come at a higher price.
On the flip side, concentrated antifreeze is more budget-friendly and easier to store for future use. You just need to dilute it before use. Personally, I find that having the concentrated version on hand is convenient for those unexpected cold snaps, and it saves me a bit of cash too.
Formula
The formulation of your RV antifreeze is critical. First off, avoid any antifreeze containing phosphates as they can lead to rust over time. Instead, look for formulas that are biodegradable and non-toxic, as they’re safer for the environment and any accidental spills.
Modern RV antifreeze is designed to be safe for plants and animals, which is a huge plus if you care about the environment like I do. Also, consider the lifespan of the antifreeze both in storage and while it’s in your RV’s system. You want a product that remains effective over time without breaking down.
Temperature Rating
The temperature rating of the antifreeze is one of the most crucial factors. This rating indicates how low the temperature can drop before the antifreeze starts to slush or freeze. If you’re traveling to areas where temperatures can plummet, you’ll need antifreeze with a rating of -50°F or even lower.
Consider the lowest temperatures you might encounter and choose accordingly. If you’re traveling through milder winters, you might not need the maximum protection, but it’s always better to err on the side of caution.
Versatility
One of the reasons I love RV antifreeze is its versatility. Besides using it to winterize my RV, I’ve found it handy for other systems like my boat, pool, and even the pipes in my vacation home. It’s a great all-in-one solution for preventing freeze damage in various setups, making it a worthy investment.
Different Types of Antifreeze for RVs
Choosing the right antifreeze for your RV can make a world of difference in how well your water system weathers the winter months. Let me walk you through the three main types of RV antifreeze available today: ethanol-based, propylene glycol-based, and ethanol/propylene blends.
Ethanol-Based RV Antifreeze
Ethanol-based antifreeze, often referred to as alcohol-based, is the most accessible and budget-friendly option out there. You can find it in nearly every RV store and big box retailer. However, beyond its affordability and availability, it doesn’t offer much else.
Here’s why I’m not a fan of ethanol-based antifreeze:
- Compatibility Issues: Many RV water systems aren’t designed to handle ethanol-based antifreeze. It can wear out certain components and leave an unpleasant taste in the water lines even after flushing.
- Flammability: Ethanol is highly flammable, which introduces a risk of fire.
- Drying Effect: It dries out rubber, meaning you’ll need to check and possibly replace seals and gaskets more frequently.
Given these drawbacks, I steer clear of ethanol-based antifreeze unless I have no other option.
Propylene/Ethanol Blend RV Antifreeze
A propylene/ethanol blend strikes a balance between the two extremes. It combines the protective qualities of propylene glycol with the cost savings of ethanol.
Here’s what you need to know:
- Protection: It offers better protection than pure ethanol-based antifreeze without the severe drying effects.
- Cost-Effective: While more expensive than ethanol alone, it’s still cheaper than pure propylene glycol.
This blend can be a good middle-ground if you’re looking to save some money without compromising too much on performance.
Propylene Glycol-Based RV Antifreeze
Now, propylene glycol-based antifreeze is my top pick and here’s why:
- Non-Toxic: It’s safe for humans and pets, commonly used in the pharmaceutical and food industries. No worries if a bit remains in your water system after flushing.
- Excellent Protection: It offers superior freeze protection and doesn’t dry out your system’s rubber components. In fact, it acts as a lubricant, helping your gaskets and seals stay in top condition.
- Revitalizes Your System: After winter, your water system often performs better, thanks to the lubricating properties of propylene glycol.
The only downside? It’s a bit pricier and not as widely available. You’ll likely need to visit an RV specialty store or order it online. Trust me, though, the benefits far outweigh these minor inconveniences.
