I'll ask this again?...Which color oil paints do I mix to get the color, Copper?
Copper is not a color, so you won't get it by mixing other colors. Copper is a material, like glass or fabric, so what you need is to properly apply positive reflections (white usually) and negative reflections (black usually) to an orangy kind of base color. If it was gold, then would be a yellowy base color; if it was silver then it'd be greyish.
There is usually some of the old oil left throughout the engine even after you have drained it.The next time you change your oil.Pick up a can of motor flush and some cheap oil.Drain old oil only and replace with a cheap oil and motor flush.Do not change filter at this time.Run engine for five minutes and then drain that oil and replace the old filter with a new one.Use a good motor oil that is recommended for your car and at the temperature range for the Season you are in.There are special oils for older engines.Older engines also produce carbon that gets into the drain pan area which also changes the color of the oil.You do not haveto do this double oil change at every oil change.
