Royal Purple Purple IceCooling System Optimizer Antifreeze & Coolant, 12 Fl Oz

I've used the royal purple ow-20 oil a few times and was pleased with the brand so I thought I'd try the ice product for my radiator we'll see if it's worthy of $$$

seams to work I'll know a little better on my next road trip,,,for my Coachmen 32 RV with a 6.0 vortex motor drive about 10, miles seams like it may be working correctly

i put in my radiator fluid it helps the car cool down boaa . i drive a grande cherokee and i could hear needed a little help to cool down man this is .ade for jeep . buy it yes i recommend this for your radiator fluid just one helps the radiator fuild lubrication parts it really does help . Houston is been extra hot on the roads and in the parking lots its a inferno so hot on the engine..thank for this i will be life long customer of yours purple royal 💜

my engines doesn't run as hard as it used too

It seems to work decently well, it's definitely anti-corrosive and 3rd party testing indicates it does what it claims!

royal purple products are quality and thats why i use them in my vehicles. walmart stocks a good supply and it saves me the hassle of going to a auto parts store.

I use this product for last 10y on Toyota, Lexus and Nissan ! works as advertised!

Still in the testing process

seller shipped product fast but when product came within 100 miles of delivery the shopper re routed to another customer. seem like very shady buisness. cannot believe walmart hasnt removed them from seller list .

I put this in 3 of my vehicles and not one change in engine temp as advertised. All new coolant and proper working setup before. I just wanted it to run cooler as they said it would. Nope engine temps are still the same. I dont recommend this snake oil treatment.
