oil turns dark fast

Ive notice that my oil seems to be turning dark fast, i think i changed it 1.5k-2k miles ago and its synthetic and said goes for 6k, is there something bad that could casuse this.

An oil's color has nothing to do with it's ability to properly lubricate the motor. All oils pick up by products from the combustion process which turns them darker. As long as it's not watery or milky I really wouldn't worry. Mine generally changes color in the same amount of time but it's still doing it's job.

While I'm at it, let me add that having a vent breather open to atmosphere on the valve cover makes your PCV non-functional and mixes combustion gases with the oil. I noticed that my oil stank of fuel after a recent change, hooked the vent line back into the intake and the smell disappeared within a day or so. I know this isn't related to your particular issue but I wanted to throw it out there for anyone who wants to keep their oil healthy and still run a PCV. And yes, combustion gases mixing with the oil will change it's color much faster.

Hmmm, can you explain why it makes it non-functional? I've got one of those cheap fuel filters running to my intake snorkel, isn't it really the same thing?
