Does anyone listen to the Automotive Hour? It's a podcast that teaches you the proper way to maintain your car. For example never flush your transmission the right way is to drop the pan and do this every 35k. Another is changing your oil depending how you drive the more stop and go traffic change 3k if you do more highway driving you can go longer intervals. The same for radiator fluid even if it says lasts 5 years. I really learned a lot from this podcast. A new episode comes out every Saturday and helps people fix their cars he even will help you if you email him.
