Questions & Answers

Is it compatible with DEF already in the tank, regular blue def? Does it clean crystals already formed or prevent crystals from forming, or both? I need to protect DEF when truck is stored in hot climate for summer months when not towing.

Answer This Question

westdrz, Thanks for the question. Blue DEF Platinum is compatible with the regular Blue DEF that is already in your DEF tank. Platinum is designed to minimize the build up of urea crystals when water evaporates from DEF. Is not designed to clean crystals that are already formed. A properly functioning system will inherently act to dissolve already formed crystals. The best way to protect the DEF in the summer is to keep the DEF tank full and park it in the shade. Sincerely PEAK Technical Product Support.

      Hi Shelly, Blue DEF and Blue DEF Platinum are used in the SCR system on newer diesel powered engines to reduce the NOx. Only use in the DEF tank. Check your owners manual for more information. Any additional questions? Please call us @ 800 477-5847.

        Product boxes looked like they were wet and damaged. I'm not impressed by the lack of care of what was delivered.

        The platinum def definitely works better. My truck has cut down on regens by half. If you care about your diesel this is definitely the way to go

        Mine doesn’t look like that. Was it priced incorrectly?

        This box was crushed and was from last summer (8/2025)which the date I did not notice until I left the store. Usually I have much better experience with purchasing this at other Home Depots. the other box of Def had no hose to dispense the product, hence I was left with the crushed box. It was sealed.
