The best RV antifreeze

Best RV Antifreeze

Antifreeze in a car or in an RV works the same — it keeps any water in the engine from freezing or raising to the boiling point to prevent damage.

The secondary use of RV antifreeze is for winterizing your RV.

Propylene Glycol antifreeze is the best type of RV antifreeze as it’s non-toxic, non-flammable, safe for all RV plumbing types, and lubricates the seals and gaskets in your toilet and sink so they last longer.

Common Reasons You Need RV Antifreeze

Keeps the RV engine running smoothly in cold weather and keeps water from freezing up and bursting lines.

To winterize RV plumbing lines before storage or during extreme cold-snaps while on a camping trip, so pipes don’t burst.

To keep water in your holding tank from freezing when camping in frigid regions so that you can flush the toilet.

RV antifreeze is non-toxic, so if it accidentally spills or you have a leak, it won’t harm the environment.

Common Benefits for Using an RV Antifreeze
