After my initial service I had the dealer put in amsoil motorcycle 10w-30 full synth. 2000 miles later it looks muddy brown and is not as translucent. Should oil discolor this fast?
Well said and thanks for your imput.Higher-revving engines are harder on oil. They often use oil to cool parts of the engine that difficult to cool. The color of the oil can be affected by excessive heat, moisture, type of fuel, engine issues, or contamination. However, changing it just because it doesn't look like new oil is usually not a good reason (unless it's white, which indicates water contamination and points to engine problems)
Rhetoric has not been proven to affect the color of oil in any way and should not be used to dictate oil changes.
