Curious how they tested the 1 million miles or the 20,000 hours. Spring time I am doing a refresh of my coolant since I have never done it for the past 5 almost 5 yrs I have had my truck, only put maybe 30,000 miles on it.
Some other company is making it where such tests were done. It's some major brand rebranded. Which one though, is anyone's guess. Read the fine print on the back (above the yellow box), 1mil miles is only half true, it needs an extender at 600k/4yrs/10k hrs.
It's only about $1.50/gal less than Final Charge 50/50, which was right on the shelf next to it. So it's perhaps not the best choice out there. I just figured I'd share what I saw.
I currently run Zerex G-05 in my RV which is about $10/gallon if you get the full strength (~$20/gal) and mix yourself with distilled water. My F250 needs a flush and replace badly but it's parked/stored right now, so it can sit like it is.
