I use the Toyota Red and mix it 60% antifreeze and 40% distilled water. What is your ratio if you mix your antifreeze? I realize most antifreezes come premixed at a 50:50 ratio.

The issue with Pre-diluted 50/50 is that about a quart or more remains in the engine when doing a flush & refill. You end up with something like 45/55 when using pre-diluted.

Now that's what I'm talking about...I was wondering if anyone else ever thought about this. YOU ARE THE MAN!

That may be true for some vehicles Eddie, but for my 04 Camry V6, it didn't make enough of a difference to change the pre-mixed -34F guarantee. Opening the radiator and both engine banks on the 1MZ_FE V6 completely drains the cooling system.

I always buy 2 gallons of antifreeze if doing anything coolant to my cars. 1 gal pure antifreeze into car/truck. Split the other gallon into empty antifreeze jug with distilled water making 2 gallons 50/50 mix. Top off radiator. -30 to -45 all the time. I then mark the remaining jug "50/50".
