Hello all, I've been told the the only anti freeze to be used in the A.M. is the green glycol?

Anything else will rot out the rubber seals at the bottom of the wet liners!
Also the oil is important, something called , Swepco ?

I've had the car 10+ years, using Castol 20/50, and yellow Prestone.

Can anyone comment on the right or wrong of these issues.
