Does DEF serve a purpose?

After 2010 tractors, pickups, and almost every diesel machine over 75 horse power is required to have DEF. For those you who don't know DEF is fluid pumped just like gas to a small motor that cleans the exhaust. Some people have the DEF deleted, which is technically illegal, but it will effect your vehicles performance. Many people do not delete their equipment because nobody will legally work on it. Sure, DEF may help the environment, but I do not think it is worth it. DEF causes too many issues and can limit engine power. Lots new machinery is fully functional aside from the issues with DEF occasionally.

Many people in the market for a diesel pickup, semi, or tractor look for older equipment that does not have DEF. The older equipment has proved its longevity and reliablity. It is key for big machinery operators to have reliable equipment. It is hard to find the right thing to buy because the newer stuff has DEF and the older has more wear to it. I know of many people who like older stuff rather than the new government regulated junk.

Personally, I think DEF has more of a negative impact than anything. It would be nice if they could still make trucks from the 2006-2008 range. I can see a trend of people buying those older trucks because they are more reliable.

 

Do you think DEF is actually helpful?

Do you know anyone who uses machines with DEF?

  • Good topic choice and good job overall Eli! Be sure to comment back on three different days. Perhaps a tad short as well.

  • I don't really know anything about DEF, but I think it could be good and bad. But I think it is good, and helpful for the environment, but could be bad for performance of cars. I can see why people think it is good and bad. But I think Def could be hepful.

  • I personally do not like DEF. It hurts the internal parts of the truck, and makes the truck less efficient and reliable. People in California have also found that the exhaust from the DEF in the truck has killed the plants on the sides of their streets. DEF also comes in small boxes. All of these boxes end up in a landfill and just add to a different environment problem we are dealing with. I definetly think we should do something to help the environment, but I do not think that DEF is the answer.

  • I do not know much about it but I think It helps the environment out more and is important for that reason, I know it's cool being able to push more power and more convienient in some cases but I think that they should make both so people have different options and let them decide what they would rather have.

  • I think that DEF can be used in good ways and bad ways. I think this because DEF helps the environment more, but is still bad for the performance of vehicles. Ideally, most people would have better performance than help the environment. I do not know anyone that uses DEF.

    • Yes, I agree. I can see both sides of it. People who operate machinery will more than likely not be in favor of DEF. I personally think that DEF is not helpful enough to use. I think that we should let people use deleted vehicles cause it makes more power and does a better job.

  • I think that the DEF can be good and bad to a vehicle. I feel that the DEF may help the environment more, but it can also worse the performance of the vehicle, which is ideal for some people to have a better performance. I am not sure if anyone I know uses a DEF, so I don't really know about that.

  • In my opion DEF can be used both in a good way and a bad way. The DEF in the equipment is used to save the environment and make it safer for the world. In our new durmax with have to use DEF and it is a pain to always have to add more and it doesn't last very long. 

    • Yes, I agree. I can see both sides of it. People who operate machinery will more than likely not be in favor of DEF. I personally think that DEF is not helpful enough to use. I think that we should let people use deleted vehicles cause it makes more power and does a better job.

  • I think it can have both good and bad impacts. It might help the environment, but for those not wanting the power of something to be reduced, I can see where it might be aggravating. I know that most of my dad's equipment and trucks use DEF and I know that he's not a huge fan of it.
