Do you consider oil color as an indicator of degradation/oxidation?

This dipstick is insanely hard to see, I usually overfill it just to where you can see oil on the braided steel part, I only have about 1500mi on the oil, changed it at the begining of june last year, I've not been driving as much. The oil is 5W40 Quakerstate Euro in my 2008 4.2L Trailblazer. The paper towel has engine oil at the top, power steering in the middle and transmission fluid at the bottom, My transmission might be on borrowed time the fluid always wipes of the dipstick with black streaks, Powersteering is clean, I changed it when I bought the car about 15,000mi ago with prestone American Synthetic, it's also got a bottle of Lubegard Power Steering treatment in it. Probably going to go 2 years on the oil, it's still got some life left in it and I don't really want to waste the OG Ultra I have the car for under 2k miles at 1 year.

I can't get over how clear the oil looks after 5,000 miles on the Jaguar.

The Jag engine holds almost 7 quarts of oil and it runs quite cool. Very easy on oil. Complete opposite of my high-strung 2ZZ-GE 1.8L in the other 2 cars. That engine only has 4.5qt capacity and runs high oil temps, especially when revved to 8,000+ RPM (but it's so much fun!)
 
So rather than going to the Doctor for a blood test do you just pull out a small pen knife and go on color?


Blood can change in viscosity though.. thinning from blood thinners or thicken a lot from very high blood glucose levels…

Just my observation but people on blood thinners I have noticed their blood did not have a normal regular red color to it. It was typically a little bit lighter vs say my blood which I don’t take warfarin.

So can fuel its called fuel dilution. Color is not a good indicator from your seat of your pants dyno!
