I am adding some wetting agent to my coolant, does the reserve coolant tank fluid get circulated?
MikeM, you are likely correct the CX-5 has excellent cooling and he may not see benefits. But a good wetting agent may help with lubricity and possible less wear on moving parts (water pump, thermostat, etc.), so I can't see how it could hurt. It's his money, do you think he's worried about that when he's rolling on $2k of wheels/tires/suspension?! (lol2)
