Is the Prestone All makes/ models a Dexcool equivalent or simply an old fashioned safe green?
Best description would be a dex-clone. Why? Well because it's not Dexcool but it has the dreaded 2eha as an ingredient.
And, while Peak Long Life and Extended Life may be the same ( I believe they are). They are not the same as Peak Global Lifetime, gold bottle, which has NO 2eha. Long Life does, and since I believe it is the same, so does Extended Life.
Read tenderlion's post right here
, it has an email response from Peak.
FWIW, I am using Prestone AM/M Extended Life (2eha) in an Altima and Tacoma with no isssue.
