From digest.v6.n875 Sat Jul 12 17:10:40 1997 I've noticed lots of 'digesters' recommending the various entended life antifreezes. Before you put the stuff in your cars, you should dig a little deaper and get recommendations from your vehicle manufacturer. As far as I know, GM is the only manufacturer that condones their use. Chrysler, as a way to beat the system, uses the orange dyes, but with regular antifreeze, in their new vehicles. Renault and Volvo, in Europe anyway, say that it should not be used in their engines. I don't know BMWs official position. Problem is with water pumps that cause cavitation (vacuum formation) which most water pumps do. Cavitation, by itself is suspected to cause pitting but, when coupled with certain components in the extended life antifreeze, causes significant impeller pitting, significantly decreasing pump life.
