Blue Def Platinum
Would RecommendThis BlueDef is hard to find. It has the conditioner already mixed in, so it is worth the price.

Would RecommendEveryone says def is def. I disagree. They all may meet the same standard, but they are not created equally. The cheap def will go through my truck in less than 1000 miles. Blue platinum will last right at 2500 miles a jug. Does it cost a little more, yes it does. But with most things in life, you get what you pay for.

Great product
Would RecommendI find the Blue DEF PREMIUM gives better gas mileage. Compared to average Def fluid. I would give 5 stars the manufacturer has to make the date of manufactured more visible not a bunch of numbers mumble jumbled together the consumer shouldn’t have to decider it.or it just leads to a deleate of the DPF & SGR & DEF TANK
