Until I can affort AT drawer system...
...I have 4 Action Packers in the back of my Xterra and they fit perfectly. One carries all my spare fluids including: 2 gal. jugs of antifreeze, 1 qt. Mobil 1, 1 qt. ATF, 1 bottle brake fluid, large grease gun (for my quad), roll of shop towels, and a couple other odds/ends. I'd guess your oil would fit. Oh, also, some of the fluids have leaked without any damage to the container, so you won't have problems with your interior.
