AD Blue Diesel Emissions Fluid for SCR Code Two 1/2 gallons (2010-2013)

You would have to try hard to spill fluid - the self sealing, self draining design is ingenious. If you buy and use these, you will ask yourself "why on earth would I ever pay someone to do that?" Made me feel like a pro! I don't want to have a big jug laying around, nor do I want to have to clean up a funnel - I am just going to order these from time to time and never worry about what to do if the adblu light comes on - these take all the guess work out of the process! Well done!

Fair price and shipped quickly. Unfortunately, I wasn't able to use the product because my car broke down. Different issue than emission fluid. Seller was great about a return and refund!

This product is excellent in every way. The description is misleading in one way. The item I got was two boxes, each had four 1/2 gallon bottles in it. Originally, I ordered this expecting to get one gallon and I got four full gallons. That is a win for me. I had originally intended my purchase to provide the basis for a funnel to add blue juice to my BMW 328d (2014 model). The bottle work great to fill the ad blue tank, and will service as funnels with the bottom cut off. The tops have a positive stop for flow control to avoid making a mess. Worth it if there had only been 1 gallon. For four gallons, and the bottles, this is a pretty darn good deal.

If you are looking for an easy and spill-free way to refill your BMW DEF tanks, this is it. I bought these primarily because of the filling nozzle. After draining both bottles, I cut the bottom out of one and now use it as funnel when using my larger 2.5 gallon. Save yourself the hassle and potential for creating a mess. Worked perfect for my 2011 X5 35d.

Little pricey. The bottles are spill proof and can be refilled. II needed them to use with bulk Ad Blue, which is really inexpensive.

Took me 3 hours to get it done for my SUV, and 40 dollars spend at Walmart to get 3 2.5 gallon AD BLUE fluid (Only 2 are needed). To reuse the bottle, I didn't cut the bottle's whole bottom, I only cut the 1/2 section(The section where u dont see the breathing tube) of the bottle, so that the breath tube stay inside the bottle while I refill, it worked out perfectly. The only pain is the refilling part, it's time consuming and slow, but it saved me 400 to have it done at dealer.

I purchased these intentionally to re-purpose the bottles. The spring-loaded bottles are really nice for filling, which is why I overpaid to get a pair of them. After emptying the bottles, I cut the bottoms off and use them as no-mess fillers. You can source DEF locally at places like Walmart to the tune of $10/2.5 gallons. I won't ever be buying these fancy bottles again, as they are an absolute waste of money. In essence, you are paying 3x the actual retail cost of the fluid for some fancy bottles.

The bottle spout fits perfectly onto the DEF reservoir receiver of TDI cars. It's a heavy duty bottle, no spill or mess. Very easy refill of DEF with this bottle
