BlueDEF PLATINUM Diesel Exhaust Fluid, 2.5 Gal

Excellent product! Walmart.com has it at a nice price at times! Rapid delivery! My 2 Ram trucks only get this BlueDEF PLATINUM Diesel Exhaust Fluid in them! I highly recommend this! Has its own nozzle. Easy to use!

when i walk to walmart in veterans metairie , i never dind this one , i find only the green cheap quality but never dind the platinium , u need to put more on shelves guys

Product quality speaks for itself. The delivery time was spectacular !! Received my order way ahead of schedule. Can't guarantee that for everyone - this time it was fast.

I will only use this product in my 2025 Silverado 1500 ZR2 3.0 diesel. I've tried other cheaper def but they reduced my fuel economy. I've actually hit 30 mpg with this product.

I had emissions problems on my 2021 Dodge RAM. After I switched to this DEF I have not had any issues. Keep in mind this truck currently has an emissions sensor recall. Make sure DEF sensor is working properly so you don’t get the wrong messages and try to go to the dealership and spend a lot of money. God Bless.

great product. gone through boxes of this Platinum def and I certainly can tell a difference in the way my diesel truck runs. I think I will continue to us this product because it's supposed to clean out all the crystal deposits in the system. On a recent 4000 mile trip pulling my 5th wheel I could tell a power difference and the engine seem to run down the hiway smoother with a noticeably better power when pulling grades.

Good sale price on the Platinum DEF. Fast shipping. The Platinum is supposed to have an additive to help prevent buildup in the exhaust system. I've always used the OEM fluied sold by the dealer but after reading the reviews on this product I decided to give it a try.

Frustrated with delivery options. I don't have the option to go to a store to pick up a particular item. I don't have to have the item right away. They always want to ship and then they cancel, delay, deliver or refund. Super annoying. It's a gamble.

I purchased this DEF product for my husband's diesel truck. Shortly after use—approximately 50 miles into driving—he received a warning message indicating “improper DEF used,” along with a countdown stating the vehicle would shut down in 195 miles unless serviced. The message also advised contacting the dealership. To investigate, he used a specific gravity tester and confirmed that the DEF was of poor quality and likely expired. Notably, this was the same brand and type he had previously purchased from Walmart without issue. He siphoned out the defective DEF and replaced it with a new supply from AutoZone, which he tested beforehand to ensure it met the required specifications. The AutoZone DEF passed the gravity test and was safely added to the truck. He then brought the vehicle to the dealership to have the error code reset and to assess whether any damage had occurred. As of now, he has been without his truck for over a week and is still awaiting a full diagnosis and cost estimate. While the product was easy to use, the quality was unacceptable and appears to have degraded. Unfortunately, there was no expiration date listed on the packaging, making it difficult to verify freshness prior to use. I strongly recommend testing DEF before adding it to your vehicle to avoid costly repairs and downtime.

I never received this item. One other item arrived and I asked the driver if there was another. She checked her van and said no.
