WD-40 Quickie

I know this information is buried in a number of threads, but I couldn’t find it at first glance. Refresh my memory, has anyone had any finishing issues due to WD-40 coming in contact with the wood? I found myself out of T-9 and didn’t want to run to the store. Are there additives in WD-40 that would mess with the end result, or can I use it for rust protection until I pick up some more T-9? Specifically, I am using some Walnut on my current project and intend to use Watco Danish Oil to finish it.
