why do engine lubrication oil change color after sometime?

Mainly the color means its actually cleaning good, which is good, or certain additives that are used may change color under heat.

oil immersion goes out to 400x I think.  low and high are 40 and 80 if memory serves.

Many supplements cause that to occur, don't worry about it.   I think it's the food coloring in it.  I bet it has a strange smell to it also.

Heat will also help break up oil.  Look at a grease-ridden frying pan after washing it with cold water and soap.  Then look at it after you have to wash it again in hot water.

It’s a pressure system, using pressure the gas or oil is moved through the system, that’s why you cant have any leaks, otherwise you lose that pressure, and gas and or oil is pumped through the system properly. Also why you have an “Oil pressure” light or picture etc, on the dash, its moved by pressure, and the loss of pressure can lead to major problems.

It could be a broken engine mount. The mount controls engine movement, if the rubber insert is broken the engine moves back and forth during a shift and can hit somewhere making the noise.

They are inert and so don't react with other elements/compounds.  Often used in situations where oxidation would occur if oxygen was present.\n\nExample:  Xenon is car head lights.  Get very hot and the filaments would oxidise (burn up) if oxygen was present.

Newer bulbs automatically refresh their volume from the gases present in the bulbs. They used to bleed off, become thinner and burn out eaiser.

I just spilled something rude on my black leather sofa & it went lighter not darker!\n\nSeriously though, very good question. \n\nIt obviously has something today with absorbency - a pair of blue jeans gets much darker, a blue plastic sheet hardly changes.\n\nAt a guess, I would say the surface tension of the water bonds it to surrounding molecules, creating a smaller surface area, thus reflecting less light.\n\nIt's just a guess, but feel free to spank me with a wet fish if I'm wrong, lol.

I have fixed the problem before changing the lithium battery.  That would be the next guess since you tried to adjust the contrast.\n\nThe next step may be checking with the manufacturer

Simple, when the oil finishes! Or a cheap and easily available alternate material is found which can be used instead of oil which is pretty difficult.

There is a special grease on the market, forgot its name but it looks like red brass in color, very good sealer for your work, a heat resistant grease.

It very well may be surface only discoloration...buff an area and see.Just because it blued a little is no reason to think it is contaminated deeper. The blueing is oxadation due to the heat.
