best antifreeze to use

I did a full doubke flush then used the Zerex G05 the yellow stuff.

That's just what I used because I had a few vehicles running that exact stuff and it was easy to just have one type on hand. It's pretty good stuff from my experience.

There is some stuff in "The Perfect Collection" on this possibly.

Typically I use the NAPA/Carquest non diluted good ol green stuff.

I have used Delo ELC for the past 15 years. Still have the original radiator in the truck. I also use it in a 2011 Taurus and in my 2017 Mustang GT. Partially for the same reason as Timd32. Simplifies inventory. I test the coolant every year in each vehicle and do not keep track of mileage on coolant. I believe that the last time I changed the coolant in the truck was about 6 years ago. Also have a hydrometer and check dilution every year. I have not ever had the coolant not pass. No pump failures since switching either. My bet is that Rotella ELC would perform as well.
