If it meets iso 22241-1 or displays the API DieselI have a 2014 TD and have purchased DEF at a local Unocal 76 station. It has it's own nozzle/pump. I have been using it for awhile and have had no emissions issues. However, can someone tell me if the Valvoline 749714 DEF is safe to use in the Cruze TD?
The poor quality has been a code since def started in 2010ish. Most times it's usually the doser injector. On semis anyways.
It messes with vehicles that have a quality sensor.I can't really even imagine what these additives would do or why they would be necessary...
I agree with you.
Def is 32.5% ammonia and the rest is distilled water. There better not be any thing else in there. Any more ammonia and you will get what is called ammonia slip past the scr and the rear nox will see it as a rise in outlet nox. Any less and the scr won’t convert
Adding anything to your DEF system is asking for trouble. I have been working Kenworth for the past 13 years and I deal with the aftertreatment systems daily. That is nothing more than “snake oil” and false claims. The scr does not affect fuel consumption. The the DPF in a regen does as the engine “in our case the #4 injector on the exhaust stroke” doses diesel fuel to react with the DOC to bring the DPF temps to between 977 and 1077 in a controlled manner to convert soot to ash and safely pass the dpf and into the atmosphere.I bought a case of DEF additive from europe. Xenum Admax.
Advanced multifunctional Adblue® additive Professional product developed to ensure the reliability of the AdBlue® system. Increases the efficiency of AdBlue®. Prevents the formation of crystals inxenum.com
I bought a case of it (shipped from europe) as my daughter plugged the scr cat in our 2017 cruze diesel - short trips while she had the car at college. The cat was replaced under warranty.
The benefits of this additive are on the page above. I recall it is a fatty acid that keeps def injector and scr cat clean. Stabilizes the DEF. And reduces the temperature it crystalizes for cold weather operation.
I would imagine that any "premium def" might use something similar and have the same benefits as admax....
p.s. we sold our diesel cruze to carmax a while back - I have a case of the admax and a case of nex10; AdMax keeps DEF/SCR cat clean and happy. The nex10 is a DPF cleaner and reduces soot for cleaner DPF & EGR... If anyone is interested, I will pass them along to you at my cost, or maybe less (I want to get it out of my garage...) Just drop me a private message.

Def is injected after the engine and into the exhaust. Hints diesel exhaust fluid. It will in no fashion affect fuel economy. What will affect fuel economy is and not limited to. Fuel quality, your foot, air temp, engine temp, stop and go vs highway driving, If your in a regen.. that’s a big one… how loaded you have the car, dirty air filter, oil weight, tire pressure but def does not help propel the vehicle in any fashion so it can not help or hurt mpg. Plus. The tank last right at 10k miles. Who here keeps up with a 10k avg mpg? And rests every full up and tries something different? Please don’t spread bad info. Check ISO 22241 and you will learn about def and how it worksI have been using Blue Def Premium. My fuel mpg increased and I have fewer sensor code alerts.
