Review on Red Line πŸš€ Water Wetter 12 oz (2-Pack) by Curtis Domus

Revainrating 5 out of 5

-30F measurable difference and needed in Arizona

We have been using this in all our BMWs for almost 20 years. This makes a massive 30F difference in cooling, which is crucial in the Arizona summer. There are far fewer electric fans powered by brake lights.

Pros
  • Oils and Fluids
Cons
  • Minor repairability
