I teach the Tier 4 Final stuff for my employer. Believe me when I say it is EXTREMELY corrosive to all metals - even stainless steel. I have seen brand new machines come into dealers with corrosion on bolts and brackets next to the DEF tank. (Probably a spill at the end-of-line test that didn't get completely cleaned up.) The urea solution is clear, non-toxic and safe to handle, however.
And 2-1/2 gallons will last you longer than it will probably stay good for, unless you put 50,000 miles a year on your truck. It has a 2 year shelf life - from the date of manufacture. If it is stored in a hot place (back of your truck in the summer), the shelf life will be shortened.
