I’ve changed a lot of oil over the years but never seen this sticky oily smelling “sludge” I guess? Oil is not that old. Should I be worried? What causes it? The car doesn’t run hot. Good news is nothing metallic.

So, I changed the oil again last weekend after running a good bit and getting it nice and hot - Oil was very clean and nothing in strainer this time. I am going to run it a few more weeks and then change oil again and see what I get. That oil that I just removed with that oil change was liquid Moly which I have always had good success with.
The oil that produced the Sludgy "stuff" I believe was Castrol (Which I normally never buy but I was in a jam after doing some work and needed a quick change). I will not use that brand again' I also had just started running higher octane fuel in it....I don't know if that adds to the mix or not. The oil in it now is Valvoline VR1 Racing 20w50...will replace it back to Liquid Moly after next change. Thanks for all the feedback and suggestions....will be curious to see what's in the strainer next time. |
