> This is also why I pay someone to change my oil. It's a simple procedure, but the list of things that can go wrong is a list.

If you're not going to change your own oil, take it to the dealership or a mechanic that you personally trust (I doubt this exists as mechanics don't really do routine oil changes). Putting the wrong amount of wrong type of engine oil into your engine is the absolute worst thing you can do to your engine.

I encourage everyone to change their own oil. If you run full synthetic (and you should), you will save a fair amount of money. Even if the shop gives you the right weight, and right amount of oil, you're not getting premium oil, and your oil filter is likely the equivalent of an empty tin can at most Tire and Lube type places.

OEM dealerships are the only places I trust to do any kind of fluid change if I'm not doing it myself.
