Here's another reason to change your own oil. So friday after work I decide to get an oil change. Normaly I do it myself but it's to cold and the garage floor is wet. Anyway...I go to a VIOC place to have it done...it's comical how they work but they change the oil anyways and I drive home and everything is fine. Didn't drive it yesterday but today I went somewhere and as soon as I got on the expressway I hear something clanging. I think for a minute and ahh. I bet the plate underneath is loose. My Blazer has a plastic plate underneath to protect it and it must be removed to get to the oil filter and oil pan. So I pull over and take a look. Sure as sheet it's hanging there by one bolt. SNAP???
