DEF
Time to add DEF to my duramax, anyone ever use the "Supertech" DEF from Wal mart? I usually use Peak Blue DEF. Any thoughts?

My guess is that it's Blue DEF in a slightly cheaper package. No box but the same pour spout..I used it, no problems. It says it meets all manufacturers requirements. If it doesn't you can go after them..
