I just had my 1994 4-cylinder Camry's cooling system flushed and refilled with Prestone Long-Life (Dex-Cool) and distilled water. My mechanic referred to it as "Dex-Cool," and being curious, I did a Google search on that name. I found anecdotal evidence both for and against it; see, for example, .
I also found that there's a class action lawsuit against GM based on the alleged troubles caused by Dex-Cool; see .
I wanted to use this antifreeze because of the extremely long life claimed for it--150,000 miles or five years--and because I trust the Prestone brand name. If you use this antifreeze in your Camry, what have been your experiences with it? TIA.
(BTW, I understand that Dex-Cool was not a Prestone invention, but I think Texaco was the first to market it, and subsequently GM adopted it (in 1996) for their cars.)
Regards,
Mike
