What should i use?

Guys, look into the chemistry, the Prestone Universal IS Dex-Cool.

Best is a G-05 spec coolant, the newer Chrysler or Ford Gold or Zerex G-05.

anyone here use amsoil coolant? im thinking about switching to that this spring. supposedly its 250k miles.....

coolant is coolant. use the yellow stuff. it is all water with a little extra.

yeah im going with yellow saturday =]

Pretty much, but without the chances of turning to sludge when exposed to green coolant or air.

It uses the same organic acids, it has the same chance of sludging up as any other dex-cool.
