I prefer the silicate and phosphate-free coolants such as Prestone All Makes All Models as they tend to have a longer service life and may be less damaging to seals.
I think the ready to use stuff is a waste of money. Think about it, you pay for one gallon, or buy the stuff you have to add water to, and you make 2 gallons for the same price,get it?
