It works, and you need to run this through your Diesel Def system at least twice a year, some kind of cleaner. I was not driving my truck as much as I normally do. It's motorcycle season, by the truck sitting all the lights, bells and whistles were going off on the dashboard. I repaired it myself via additives through the Def and Fuel system and Running the engine. I know now ; not to let my truck sit that long. I literally let my truck sit for at least three months without driving and it caused the truck to go into limp mode four times. I repaired it using additives. The dealer minimum of $1200 ; if they had to drop the tank which you know they would have said “ we have to drop the tank” $2400-$2700. The first time I used peak platinum which cleans the Def system out it makes it run hotter. You could smell it. The truck only had about 27,000 miles .So if you smell a funky smell, i it. Is this product doing its job properly, do not panic.✌🏼👍🏼👍🏼👍🏼

BlueDEF Platinum Diesel Exhaust Fluid has been a dependable choice for my diesel truck. It's easy to pour, meets the required specifications, and helps keep the emissions system running smoothly. I've never had any issues with warning lights or performance when using it. The packaging makes it simple to handle with minimal spills, and it's a product I trust for regular maintenance. If you're looking for a high-quality DEF that delivers consistent performance, BlueDEF Platinum is an excellent choice.

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.

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.

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.

A good price for this item. Dont know if i need the platinum, but I figure during the summer months its better to use it since DEF expiration is temperature sensitive

pakage damage it loooks like containers were leaking..not driver fault...
