What Def are you using in your Diesel?

Can someone decipher this date code if it is a date code because I can’t find anything similar. I just picked it up and I’ll bring it back If this is really three years old. The sticker on the box has it arriving at the OnCue station February 3 this year.

Read recently that Peak Blue has changed their date codes. Looking at that stamping it doesn't make any sense to me. All Im getting lately around here is Air 1 so I phone them and they sent my their date chart, maybe find a 1 800 number on the box and call them up to explain it to you.

I’m a first time diesel owner. Just got my 2023 Ram 5500 SLT Cab Chassis and after doing some research I am pretty sure I want to use Peak Blue Def Platinum for my Ram. What are your opinions on using Regular Vs Platinum if you have used both?
I’ve seen the def injector stays very clean using the more expensive Def.

Like you, I live in a hot climate and heat is brutal on DEF. I have to drain my tractor DEF tank out every 3 months or it starts to crystallize. For my truck, I buy it at Loves when I fill up. I will also go to Walmart and Tractor Supply because they seem to turn over inventory pretty fast. All DEF is the same, the box is marketing.

To me it reads 08-12-2022.

I though so too but thought its too damn simple for them to do that.
