Whenever I am driving, a thought often occurs to me, "Have any of these cars around me had an oil change recently?". I often drive around thinking that my car is the only one with fresh oil in it with the level at the full mark and everyone else is driving sludged engines two or more quarts low. I know this is not always true, but I take pride in maintaining my vehicles and seeing how most people I talk to are either ignorant or apathetic (usually both) when it comes to vehicular maintenance, it may as well be true. And don't get me started on ATF flushes! Anyone else have similar experiences?
