Last time I stopped at an AutoZone that I've never been at, the kid trys to sling Lucas fuel injector cleaner. I said sure if he could explain how it worked without having any solvents in it. Hadn't a clue. I buy sub $300 cars and beat them to death because nobody wants to get their hands dirty or even try to fix things. My caravan was pissing coolant when I bought it. The previous owner said it was a nightmare job and expensive blah blah. $6 on rubber heater hose, a couple clamps and a zip tie. That was 12k miles ago. My 1978 snow blower sat in a basement for 20 years. Cleaned it up. Changed the belts and fuel line and it purrs. My hair Clippers are getting dull. The company suggests a new head or the newest model to replace my older one. Going to buy 600 grit sand paper and put a new edge on it. This isn't rocket science. It's maintenance.
