Motor oil accident! Need some help!

I'm fairly new to the raw denim world but bought my first (and only) pair of N&F about six month ago. I wore them almost everyday and they quickly became my favorite jeans.

Flash forward a to a few weeks ago, I was helping my buddy moves some stuff out of his garage and I go to grab what I though was an empty Folgers coffee container from a shelf. Surprise to me, the lid pops off and it's filled to the brim with used transmission oil which is promptly spilled all over me.

Everything was pretty much trashed right away but I really wanted to try and salvage the N&F. I have obviously given up on the no wash or gentle soak life for these as it's either I get the oil out or they are going in the garbage.

Currently I have tried, soaking, washing, baking soda, dish detergent, vinegar, washing hot, soaking again... you get the idea. There is no stain anymore which is promising but they are still "oily" and smell very strongly of motor oil still.

Does anyone have any hailmary ideas for me to make these wearable again?

TL;DR: Spilled transmission oil all over jeans, can't get oil out no matter what I try.
