I've got a birch butcher block countertop from Home Depot that I plan to use as a worktable. It suggests using mineral oil for protection. Is it necessary? Could I use lanolin oil instead? I really love the natural look of the wood as it is. Thanks for your help!

If it's mainly for food prep, consider finishes like General Finishes or Walrus Oil designed for butcher blocks. The recommendation for mineral oil is because it's user-friendly and assumes you'll use it for food. However, it remains wet and could be a hassle. Linseed oil is a great, cost-effective alternative that cures nicely and protects the wood well.
You should oil it periodically regardless of the oil you choose. The type depends on how you plan to use it. If you don’t do anything, the wood can split. Mineral oil is good for food surfaces but needs regular reapplication. For a workbench, I’d recommend linseed oil—it lasts much longer and is easy to apply.
If you're going to eat off the surface, definitely stick with food-safe mineral oil. It's the safest option for protecting the wood during food prep.

But if it's just for a work table that won't be used for food, then other oils should work fine, like in the garage.
