Depends on the leather and why you're treating it.
Mink oil does a good job, but many feel that it will eventially destroy the stitching. I've not found that to be the case. My Bean boots have been treated with nothing but Sno-Seal once a year since 1985. Yep, they're nearly 30 years old. I've sent them back to LLBean 3 times for new soles as they wear out, but the leather is original and in great shape. They serve me well in snow and ice, as well as the 100 degree dove fields of Texas. The stuff does the job. I've even treated my Saddleback briefcase with Sno Seal and really liked the result. Many swear by Obenauf's and it has a great reputation. It is similar to Sno Seal.
For my Red Wing Iron Ranger boots, I use Red Wing Boot Oil. Rather than purchasing it, I just go to my local Red Wing store and have them perform the free oiling and put on the free laces 2x per year. Easy...
Best oil for treating leather goods? Does it matter what kind of leather it is? Wanted to buy something to eventually treat by Filson bridle leather straps on my bags and LLBean boots.
A friend recommended mink oil? Is that a good purchase?
Saphir Renovateur for dress shoes, and Obenauf’s LP for all other.
Neatsfoot oil is the traditional oil for tanned leathers.Best oil for treating leather goods? Does it matter what kind of leather it is? Wanted to buy something to eventually treat by Filson bridle leather straps on my bags and LLBean boots.

Mink oil will soften leather, but you’ll never get another shine on it again without serious, long effort.
