We got my grandma's car in our possession recently, said she has no interest in driving and she's not in the best shape to drive anymore anyway. Well the oil has been changed pretty regularly in the past few years. However my dad suggested today I change it and put new plugs and wires in it cause we're trying to do every basic thing we can to get it running a little better.

Well, I drained the oil, and I was surprised. It looks 100% identicle to chocolate milk. The kind that you can get at wal mart in the gallon jug? The real thick stuff? Looks no different than that.

What in the world could of caused the oil to do that? I'm certainly not a mechanic, but I can do basic things to cars, such as the oil change and plug changing. Any input?
