Review on πŸš€ ACDelco GM Original Equipment 10-4022 Diesel Exhaust Emissions Reduction (DEF) Fluid - 1 gal for Improved Air Quality by Lild Zimmerly

Revainrating 4 out of 5

Missing the essentials

This may be a good product but like other expiration dated products the expiry date must be clearly stated. The date code on this container is completely illegible. It's impossible to tell how old it is unless you can read it. Half of each number/letter isn't even there. I even tried to decipher the code with a magnifying glass. Bad luck. It's not worth a costly DEF repair to top up old expired fluid. I bought a gallon of PEAK in the same order just in case something like this happens. The PEAK container has a unique date code and it was this year (2020).

Pros
  • High quality formula of high purity urea and deionized water.
Cons
  • Expensive
