O rlly?
How motor oil color affects performance. (Hint: It doesn’t). - AMSOIL Blog
Oil color is not an indication of the lubricant's condition. Oil analysis is the most accurate way to know a motor oil's condition.blog.amsoil.com
I disagree to certain extent with that idea oil color doesn’t matter…
The following oil I bought off the shelf from a gas station 2 miles west of me looked that jacked up right out of the container. This oil was on PQIAs list of extremely bad oils… Interestingly the store I got it from is not in a poor income area… That gas station is in between 2 large and very high end nice neighborhoods… One neighborhood that is a gated community north of that gas station by a mile. The other non gated but very nice high end neighborhood to the south of it by 1.5 miles. Those people routinely stop in that store to buy gas, snacks etc etc.
Then for comparison I put Valvoline white bottle 5w30 to compare… . Every single oil I have ever run looks like that Valvoline prior to it being run in a vehicle. I know that are other oils that have a different new color in them like that one Liquimoly Molygen green oil and there are a few others. But not many.
Or if used oil looks a bit like chocolate milkshake.. You got a major, major problem there.
Used Diesel oil color certainly doesn’t matter because it’s jet black very, very quickly. Even used oil in a GDI motor gets dirty quite fast as well based upon what members on here have observed.
In port injection motors used oil color is a fair amount different and is worthy of paying attention to its color.
So the blanket statement that “ oil color doesn’t matter “ is patently not true in my strong opinion.
What type of motor it is run in matters…. A whole, whole lot.
Now if a decision to be made whether a oil is still serviceable… Then absolutely yes.. Oil color means absolutely nothing. Only a used oil analysis would give that answer.
*** Only caveat to that rule is the aforementioned oil looking like a milkshake in a port injection motor••••…. Which if the oil looks that bad… It’s been doing damage to that motor for awhile potentially.
By the way my calico cat approves of this message…
