Used Castrol TWS oil color?
Changed the oil yesterday (OEM Castrol TWS, 7000 mile interval) and was alarmed to see that the oil showed signs of a blood red color.
For reference, my car is a 2009 E90 with a little over 26000 miles and babied since new. Anybody seen this before? Should I be more worried than I already am?? Thanks in advance! |

It's black, black and black. Unless you put red color. Even so, the used oil is so black you won't see anything. I just changed mine. Hope this helps

Thank you for the responses so far. I will try to see if I have a decent photo. I noticed the color of the last few drops draining from the main pan and was able to verify upon draining the secondary pan closer to the front as well as changing the filter.
First thought it was from DCT fluid contamination only to find out later that the DCT fluid is not red like most ATF but instead clear / amber new or dark brown used. No leaks from what I could see and the car drives fine. FWIW, the car is bone stock The used oil had about 7000 miles on it over the course of almost exactly one year. During this period, the oil level dropped from the max line to the 3/4 mark which was normal rate of consumption compared to past intervals. Unfortunately, I did not have the foresight to collect a sample for analysis. My only theory right now is that the oil was contaminated with water from condensation as a result of not driving enough and the engine not reaching ideal operating temperature. Any other theories would be appreciated. |

The golden amber of fresh oil turns slowly darker as it degrades and is used. It could look slightly orange or reddish before turning darker brown and then black over time. Could be normal or you could have filled the engine with Kool aid during your last oil change.

ATF is usually red. Are you certain TWS was put in there?

I really hope that you are right and that this is the case. I will try to get a sample from under the filler cap and take a closer look using your tissue paper suggestion. |
