Royal Purple 01600 Purple Ice Super-Coolant Radiator Additive - 12 oz.

Excellent product !!

I still like to drive one of my older cars regularly. Over the years it appears that there's some build-up that just will not flush out of the engine. This only affects the car when the Houston temperatures get into the mid to upper nineties. The car does not overheat but it runs hotter than I would like. I tried the purple ice, Which coincidentally I installed during a multi day period Of nearly 100 deg. temperature days. To my amazement my engine temperatures were lower (even when compared to the gauge reading during the lower 90 deg. temperature days). There are people out there who believe that your car engine thermostat will just adjust to compensate for any improvement the product may cause thus rendering purple ice ineffective. However think about this logically, the reason a person would add this is because during periods where your thermostat is completely open and is unable to provide any more cooling your temperature may still increase.... and this product is able to help disperse that increased heat in some way by its chemical formulation... again, Your thermostat is fully open and your engine temperatures continue to climb non the less....adding this can help Another way that this product indicates its effectiveness is that my engine takes longer to reach operating temperature by about triple the time. So this product is absolutely doing something to help the coolant release heat. And for those that think that there is a problem with driving your car for 15 to 20 extra minutes before it reaches operating temperature asked them to phone their friends in Wisconsin Minnesota Alaska in other extreme cold States and they will find that this is normal for a few months a year with no adverse effect on your car engine reliability.... Sorry for being so long.. this product works

I use this in all my cars. It does lower the operating temperature as stated. Cheaper on Amazon than your local parts store

This coolant performs well and helps maintain stable engine temperatures under regular use. It feels like a quality product that supports consistent cooling performance. It mixes and circulates without issues in compatible systems. It’s a bit more expensive than standard options, but the performance feels solid. Overall, it’s a dependable coolant for maintaining engine health.

Honestly I can't see a difference. If my vehicle had an actual temperature gage instead of bar graph I could tell. Still, I'm giving it a chance. Fingers crossed.

Works great

My car is still overheating but to be fair it might be my radiator cap?

Two bottles is what usually works on my big block 10 degrees or more cooler ! Ice ice baby !!

Buen producto. No debe usarse completo, sino por onza en cada litro si tienes mezcla 50/50 anticongelante ( si no, no te sorprendas que haga espuma; además que no sirve de nada ponerle una mayor proporción a lo que indica Royal Purple). Por otro lado, no esperes una baja de temperatura, sino mayor capacidad de "reducción" de temperatura del sistema de anticongelante, y la confiabilidad de un aditivio que alargará la capacidad de flujo del anticongelante y la vida útil de tus mangueras. A veces buen precio: 350 pesos.

Una bomba! Unico neo, va a sciogliere eventuali prodotti per rattoppare le condutture... quindi meglio usarlo su auto che non hanno problemi di perdite, perché é com l aspirina per gli esseri umani! Ringiovanisce i condotti

Amazing product, had to try but it works, superb quality, does what it says.tried on my nissan juke 1.6 turbo and cools much better dropping the temperature much more quickly than just normal coolant. Temperature between 84 degrees and 87 degrees.

جيد

A must add to your cooling system. Keeps the temperature down in summer heat. My car runs cool.
