I bought because you never have to change it. Works well no problems.

Always had to refill my coolant when using 50/50 coolant due do water evaporation. Now my coolant level doesn’t drop, making my sea doo spark less likely to have problems out on the water. Now I’ll be switching to evans for my VW golf and Yamaha scooter so I only need to keep one type of coolant for all my machines.

Nicely packaged. Got everything I asked for. I was just missing the evans stickers to put on the rad caps... I have a feeling they should be included.. Not the worst problem in the world.
