Glad to hear you have good luck with em, My brother-in-law runs em in his 96 Silverado and swears by em, it runs good too. I had a bad trip with em in my Olds, they werent +4, just the plain plats, but that was my experience.

Update, changed the Trans modulator, Seafoamed the engine again, (more smoke), have put about 550 miles on it since Sunday and today it seemed to run better than it had, maybe since I got it. It seemed to cruise home effortlessly tonite. Maybe she is as glad to get home as I always am. And it was 102 degrees today.
