I don't know about baking soda. Fuller's Earth is what I was taught to remove oil.
But the problem, as I see it, is two-fold...first, rubber by itself will mark floors and sometimes can, itself, softened or almost dissolved by oil. So the rubber on a shift lever could be contributing to the stain.
And second, if the grain has been abraded by the rubber of the shifter...even if only at the microscopic level...then the oils in the boot will pick up rubber and dirt and so forth and transport it past the grain surface and into the underlying fiber mat. Even if you pull the oil with the baking soda or fuller's earth, the rubber and dirt may not automatically come with it.
And of course, once the grain surface has been broken...esp. on light coloured leathers...the fiber mat will always pick up dirt and oil at a faster (and darker) rate than the surrounding leather.
If what I suspect has happened prove to be true, I don't think...I don't know of...anything that can fix it.
There may be something that I am not aware of on the market or some trick that I don't know...I try to deal in new leather not worn...but it
doesn't look promising. Sorry about that.
