I was going to purchase a three pack of auto-rx on sale for Christmas, but a seemingly knowledgeable person at Pep Boys persuaded me to purchase CD-2 for sludge clean-up, and Lucas for an oil treatment. I know auto-rx is reall the way to go, but are these products decent, worth using, or should I return them. I trust all of your opinions so much I thought I'd ask first. Oh, I drive a '96 Buick Lesabre 84,000 miles. Long time reader first time poster!
