PrestoneAS240-12PK Washer Fluid Booster De-Icer Additive with Dirt Blocker-15.5 oz, (Pack of 12)

for eight dollars and change this bottle only makes one gallon of deicer windshield fluid. a gallon of windshield washer/deicer fluid in local auto supply store cost less than five dollars for a premium brand washer/deicer

The package arrived on time and was exactly as described. I have used this product for many years and it works great. Ordering online and having it delivered to me was much easier than driving around to several stores trying to find out who has some in stock. The price was almost the same as in the store without me having to drive all over to get it.

I always keep a bottle around. You never know what some service tech put in your tank and ensuring it will not freeze is just smart. Granted, I only test it down to about zero, but I've had no issues and I've been using it for years.

This was the truck I needed to keep the cheap washer the dealer put in from freezing. I learned my lesson and I will keep it topped off with good low temp fluid before they add cheap stuff at the dealer

I've had the worst luck with frozen nozzles for the washer fluid when it snows even using the -20 fluid, added a bottle of this and haven't had a problem with freezing so far.

Used it before when the washer fluid froze years ago. AutoZone no longer carried it. Found it on Amazon for more than I did the first time in Autozone. It works great if your windshield fluid freezes. Takes a few hours to work after pouring in.

My work vehicle gets filled with the water and tab windshield wash (which is almost useless in the winter). Gave this a shot, and it’s got my approval. Windshield wash nozzles sprayed, and didn’t freeze up either.

This stuff is great for saving a washer resovior from freezing when bug wash is used all summer and the weather changes
