FWIW, I had no qualms as I've proably done 4 or 5 bolt drain refills prior + at least 1 pan drop, no filter change .

The 2-1 started sometime ago and I was due for my pan drip, filter change anyhow. This time we just did the whole fluid. I can't recall but I think we used around 11 quarts. That made my 2-1 go away FWIW..
