I change my own oil. Only time I revert to other people doing it is when I'm in a hurry to leave town and notice I'm like 2 grand over the milage limit. But really I like changing the oil in my car. I get to pull up the car in the garage and jack the front up, crank the radio to 10 on whatever old school rock station I find, grab a beer and take my sweet time with it. Make the neighbors think I'm a gearhead. I can usually pull this off, though not so much in my wifes compact suv. Btw, I never dispose of my oil in a timely manner. I'll just funnel the old oil back into the jug that came with the new stuff. Seriously, I got like 25 liters of used motor oil. If anyone wants to kill Wefalds grass PM me...
