How many of you still do it?
I do my own for a coupe of major reasons, despite the fact that I don't save much money and hate getting hot and dirty.
I don't trust that oil change places will...
1.) let all the old oil drain out. I'm obsessed. I start the oil draining in the morning and let it drain for hours. I literally want every drop of old oil and dirt out.
2.) use the full synthetic that I pay for. They can and probably do either use bullshit oil or at least "watered-down" synthetic. I want name-brand shit from Costco.
Also, using the best synthetic, I only change it every 30,000+ miles. A guy from a machine shop showed me years ago that the old "pinch test" for oil is all you need. If you pinch the oil between two fingers and then you have any sort of "pull" as you separate your fingers, you have all the viscosity and more your engine needs from the oil. Changing oil every 3k miles is a silly gimmick of those who profit from it.
