Just so you know, this has nothing to do with riding, but its a funny story and good example of how mechanics take advantage of the non-technicly inclined. Yesterday, im in the car with my mom, and she realizes her jeep is due for an oil change (which I offered to do for her many a time) so we pull into the oil can henrys. Well, we get the standard oil change, and then, as this old wanker is looking under the hood, he puts on his most concerned, shocked look he can muster. He puts his hands in his pockets and waltzes over to my mother. "Ma'am, theres a problem, you're cars coolent is in serious need of replacement, and you're system needs a serious flushing." and my poor gullible mom replies, "Oh, well I better have that done then, how much is it?" and he replies "well, that'll cost you around 70 dollars. Its well worth it, otherwise you're car could overheat and you could be in some very serious trouble." Overhearing this I get out the car and walk over to this guy, and ask him what exactly is wrong with our "coolent". He tells me that its become overused and is showing signs of breaking down. Then I asked him how water and antifreeze breaks down, and asked if he could show me the "coolent". So sure enough, he takes me over to the radiator, opens the filler cap, and says, "you see that, how its looking pretty old? It's starting to lose its cooling properties." And sure enough! He was right!!! The water was clear, and green with antifreeze!!! (not to mention that i had replaced the radiator with a new one when the old one was punctured, so the coolent was but 2 weeks old) Obviously in dire need of replacement. Well anyway, I told him that he was full of **** and if he didnt charge us anything for the oil change I wouldnt report him and the oil can henrys to the BBB. Anyway, once again proves, that you should never let anyone who doesnt understand cars walk into any kind of service establishment alone, its like throwing a baby lamb into a circle of old, greasy bastard foxes.
