Just thought I would pass along an article that I read in one of my trade magazines, Motor Age. You cant view the magazine unless you have a subscription but if you go to
www.searchautoparts.com and type GDI into the search engine it pulls up the article. It has some very good information on the subject with GM and Ford both adding comments. Thought some of you would enjoy it. Tracey fell free to comment on the article as you probably have more knowledge on the subject than the authors do.
