I have been an engineer in the auto industry for more than 40 years and I am a car nut. I am a member of several car clubs and forums and am amazed at the tremendous amount of misinformation that gets published. Here you can get the facts without the BS, and if you want the science behind your questions, I can give that too.

If you are an auto enthusiast and want reliable information about car repair, modification, or car shopping advice, you can get it here. – Dave
