I just got my oil changed and I was about 500 miles past my due date. The guy told me my oil was pretty dark. After the oil change my oil was still a little on the dark side. What can I do to fix this and Is this a sign of another problem

how many miles on her

sign of a dirty engine. change more often like every 1k to clean it up, may want to use cheap oil to do this then go to the good stuff

My oil was consistantly dirty after oil changes, so I bought 5 quarts of cheap stuff, drained the old, put in the cheap stuff, ran it for a little while (like a quick 5 minute drive), drained it, changed the filter, put in the good stuff. And it'* looked pretty good ever since.

i also hear you can dump some sea foam in the crankcase before you go to get your oil changed. i did it, and got nothing but a clean engine.

*agrees* i did it before i switched to 0w30 in the jeep and saw nuthin but a clean smooth running engine, gotta love that seafoam especially when u run it thru the vacuum system and fog out ur whole neighbourhood

Many oil change places move cars through pretty quickly and don't allow for all of the oil to drain completely. As well there is a certain amount left in the bottom of the pan once supposedly all oil is drained. Do a couple of changes sooner and use better filters for the best results.

on the bad news/worst case/paranoid end of the spectrum, piston ring blowby can cause dirty oil (not saying it'* that, but it can cause)
