I just purchased a diesel. I went to autozone and bought the 2.5 gal blue def. It was like $16 or $17

Is there a more affordable way/location of buying def?

I use this vehicle for business and average 200-300 miles per day so I will need to add pretty often.

 

Walmart, it's 6.88 for the 2.5 gallon of SuperTech. The next cheapest is at the truck stop, it was 1.89 a gallon yesterday.

 

 

Thank you. Walmart it is!

 

I'm new here... but why did a DEF question end up in the 7.3L forum?

 

You tell me and we'll both know, my truck doesn't use it.

 

Yeah I felt like I was on BookFace for a minute and I was waiting for him to say he was adding it to his fuel tank on his 7.3L; along with all the ATF the guys on FB are running in their tanks.

I'm guessing he has a newer diesel and just ended up here somehow.

 

Oops. It's the forum that I'm used to. Selection by habit.

 

In addition to my Superduty I have 2 more oil burners (Sprinter motorhome and TDI) and they both use DEF. I wish there was a better (legal) way, it's kind of a pain. Unless you count my wife's car I am now gasoline free. Most important to me is making sure I only get fresh DEF as it does have a shelf life and the heat where I live is not ideal for it. Funny thing is the PSD has 2.3 liters more displacement than the other 2 put together.

 

****. I just purchased 6 of them from walmart today. i do 5k miles per month. Is there a way to know how much longer i can keep them?

 

The date code is right on the containers. It's two years from manufacturing.

 

Gotta say that cracked me up!

 

Is that La Vache Pee Pee then?

 

Happy Cow, Happy Engine.
