ACDelco GM Original Equipment 10-4022 Diesel Exhaust Emissions Reduction (DEF) Fluid - 1 gal, white

Using DEF means being fussy about the quality to minimize problems on the road. This product has been consistently a good performer over the years.

Local dealer was out so I picked some of this up from Amazon. Shipped quickly and came with an easy pour spout. First Diesel GM vehicle so I'm using this fluid as recommended.

Added this Def fluid to my 2021 Chevy 2500 HD. I was tired of paying double for Blue Def. No issues and is actually recommended by GM. Ordered and delivered in a timely fashion. Would definitely use this vendor again.

I bought these because of the name brand and the smaller containers. Just a girl who loves her diesel truck, but I can’t lift the big jugs they normally sell in the store. I like to keep extra in my truck and these are easier to store and move around. Yes, they are more expensive but worth it for me. I was a little worried about the fact that there was no seal under the cap and this stuff looks like water but I bought a refractometer specifically for DEF and they test spot on at 32.5%.

Whats to say, it original equipment and can't go wrong. Pay more from a dealer.

It's DEF, it works, but the container I got is smaller than other brands. Glad I got 2.

Bottle had previously been opened. The cap was on and a tape applied over the cap. The tape said 'cap seal pac20711' The bottled had leaked.

Tired of picking up and pooring a 2.5 gallon of DEF. Then this is the answer. Lighter in weight and easier to pour. Also easy to carry one in truck in case of need.
