Got 5 quarts (well, got them ordered). We'll see if old AZ has misreported inventory levels (again). Last time I ordered 5 qts of oil online, they only had 3 of 5. : (

They've done this to me a couple of times over the years. Hopefully, they'll just substitute another brand if they are short a couple of quarts.

Thanks OP for posting. Left you some reps. ✓

I went to pick my order. The staff member was lazy and just grabbed something that looked similar to what I ordered, Castrol Edge instead of Castrol GTX. It worked out for me because it looked like they didn't have the actual one here in stock anymore.
