Speak to the mechanic
Like computers, nobody knows anything about cars. Unless you’re a grease monkey who spends every waking hour polishing their vehicle, you probably have no idea where to put the blinker fluid or how to maintain the exhaust drive. Thankfully, you can speak to a mechanic about your car woes.
We mean speak to the mechanic, not the person behind the desk whose job it is to sell you as much useless crap as you can afford. If you care about your car, you should also care about your mechanic. Creating a personal relationship with them will mean receiving better diagnoses on your car troubles.
