Has anyone tried changing your water to coolant ratio since Optimal Coolant Ratio Depends on Your Climate for added benefits....
FWIW I was thinking of a
70/30 water-to-anti-freeze mixture and prior to winter switching back to 40-60.
Here's a good article below.....
Since the lowest freezing point is achieved at a
40/60 water-to-anti-freeze ratio, there's no added benefit to using more anti-freeze. Therefore, if you live in an area that will never see less than 26°F, your car's performance will most likely be optimal at a
90/10 ratio year round.
If you live in an area that can see temperatures as low as -10°F in the winter, but can also get to 95°F in the summer, then you're better off running a
60/40 ratio. However, if you're one that may get stuck in traffic with the air conditioner on during the summer months, you may want to make the switch to a
90/10 ratio until winter hits again to get the most out of your car year round.
Make sure to read your vehicle's owner's manual to find the coolant system's capacity so that you can figure out how much anti-freeze to add! https://www.ngk.com/learning-center/article/653/quest-for-the-ideal-coolant-ratio
