Here are pictures of 4 samples of oil....Sample 1 is Castrol Edge EP 5W30 with 2,128 miles on it, Sample 2 is Amsoil SS 5W30 with 37,774 miles on it (and I have UOA on it, still usable), Sample 3 is unknown Franken brew from my 5 gallon garage drain pan, and Sample 4 is Amsoil SS from my daughter's car with 5,944 miles on the oil. All I ask of anyone is to pick out any sample and post correctly which one it is; or else admit that the color of the oil tells nothing other than the color of the oil.
