I was just trying my new fluid evacuator out. So I pumped about 2 quarts of engine oil out of my 2016. I had my oil changed at about 1850 miles, and I have about 2050 now. So this oil has 200 miles on it. I was literally watching it go by through the hose. Blackish already and a faint whiff of gas. Made me glad I bought my new evac. My gasoline engine vehicles in the last 20 years never had oil that looked like this in 5000 miles. Very much reminds me of how fast the diesel engines I have worked on blacken thier oil very fast

Why are you changing oil with only 200 miles on it? Color of the oil has no bearing on if it's "good" or not.

And why not drain it like normal--

That's was my question as well.

I wasn't changing my oil. I was trying my evac out.

"Color of the oil has no bearing on if it's "good" or not"
First of all, I did not say it was "bad".
Secondly, you know this how?

Do have confidence that the evac is reaching the bottom of your engine's oil pan? Reason for asking? There is dispute as to whether the 2.7's oil drain-back valve permits access to the bottom of the sump and complete oil removal via the dipstick tube.

It's kind of hard to say. I am pretty sure the hose was in as far as it would go. The problem is that I wasn't getting a great seal where the hose goes into the dipstick tube, so I was losing the vacuum pretty fast. I am going to get a soft rubber grommet to place around the hose to seal it there better. Again I wasn't trying to completely empty it, just checking things out. But I am going to say you probably won't be able to completely empty it if you are doing an oil change. I'll let you know once I get a grommet on there.

I posted this pic from the service manual in another thread. I don't think the dipstick tube goes to the bottom of the pan.

Very interesting. If you extrapolate, that's my two quarts down to the bottom of the dipstick chamber. I wonder what the check valve is for?

Many oils are different colors, shades and tints. Royal Purple is, well, purple. (Yes I know your truck didnt come with Royal Purple). Some oils are a very light color while others are much darker.
Color alone does not necessarily indicate its condition. The best way to find out the condition of your oil is by an oil sample analysis. It will tell you if there is any metals, antifreeze, fuel and of other contaminants and other properties of the sample. The data gleaned from the analysis will give an excellent indication of the condition of the oil and of the motor it came out of.
