OEM is formulated to the manufactures specs. A lot of part in an engine are coolant sensitive. Why mess around with something else?
Ok, so what should I get mate? Honda formula?

You can use whatever you like as long as it meets spec for the vehicle. I use Amsoil coolant with their dominator coolant boost.

Zerex's blue coolant will work fine in your car, it is basically the same as the Honda Type 2 coolant that was put in your car from the factory. If sticking with OEM fluid helps you sleep better it's not expensive to get from a dealer. Both will be problem free.

For my radiator upgrade last weekend, I went with genuine Honda coolant. It's about $25/gallon. I've used Zerex with several of my Hondas without concern, but the closest Honda dealership is 3 minutes from my house. Plus, I never lavished this much attention on my previous Civics, CR-Vs, and the Fit.

Just remember if you live in warmer climates you should run a 60/40 ratio of water/coolant to keep temps down

I'll usually use either Zerex or Peak, have had zero issues with either one. I recently used Peak when I drained my coolant to change out my thermostat and radiator hoses.

I got this, haven't changed it yet. Does anybody know how many Gallons/Liters come out for a drain and fill? I have 2 gallons aka 7.56 Liters. And my pan holds 11 quarts.

I never had any problems running hot until I was tracking my FK7 for more than 20 minutes. The ECU started cutting the throttle, and my coolant temp was around 220 F. I was running Zerex coolant with a stock radiator, and it was about 80 F ambient temperature. That's when I decided to upgrade my radiator.

I could see an argument for adjusting ratios in a much warmer climate zone, where it rarely gets below freezing. We see temps temps from over 100 to -25 F in Nebraska. I don't want to mess around with ratios.

It's about a gallon with the 1.5T. When I flushed the OEM radiator a couple years ago, I don't think I got a whole gallon out. This time, with a radiator swap, I've put in exactly a gallon.
