Being an automotive specialist, I’ve been experimenting with increasing the mileage of 6.7L Powerstroke engines for the last decade. There are many reasons behind that, but there is a special one that comes to me most times. Want to know what I found out?
Doing a DPF (Diesel Particulate Filters) delete increases the mileage of a 6.7 Powerstroke vehicle up to 50%. That’s why I’m going to tell you the exact benefits of doing a DPF delete (and its drawbacks as well).
Also, you will know the MPG of your vehicle after you delete DPF. So, let’s see everything about this, and learn some magic tricks.
6.7 Powerstroke Mpg After DPF Delete: BENEFITS vs Drawbacks
| BENEFITS | Drawbacks |
|---|---|
| Increased MPG on the highway | Costly process |
| No need to maintain or repair the DPF | Harmful for environment |
| No more replacement of DPF is required | |
| Enhanced power output from the engine | |
| DPF removal allows the vehicle to also use biofuels |
If you want to know some specific info on MPG of 6.7 Powerstroke after deleting DPF, I can tell you that your vehicle will run additional 4 to 5 mile per gallon of fuel after DPF delete.
However, as you can already see, there are some drawbacks to deleting the DPF of a 6.7l Powerstroke engine as well. So, I suggest you read my take on this topic below and get comprehensive knowledge on this right now!
What Is The 6.7 Powerstroke MPG After DPF Delete?
In a 6.7L Powerstroke engine, you might get up to a 50% boost in the mileage or fuel economy after doing a DPF delete. It’s because the job of a Diesel Particulate Filter (or DPF) in a vehicle is to filter the soot’s from the exhaust air leaving the engine, according to Wikipedia.
Consequently, a DPF filter gets filled with contaminants and soots after a few days of engine runtime. At that point, the engine has to burn additional fuel to get rid of the accumulated contaminants / soots.
That’s why having a DPF filter is definitely beneficial for the environment/atmosphere. But, a DPF puts a heavy strain on the mileage of the vehicle. So, your vehicle can not achieve full-fledged fuel economy with a DPF installed.
Now, let’s say some specific info on the MPG of a 6.7L Powerstroke engine after DPF removal:
- According to real-life reports, people, who used to have 15 to 16 MPG fuel economy in their vehicle, enjoyed up to 20 MPG after DPF Delete
- In terms of raw horsepower, I observed that deleting the DPF of a 6.7 Powerstroke engine increases up to 100 horsepower for the engine
- The maximum benefit of a DPF delete is observed when riding the vehicle on the highway.
For example, a vehicle that provides 16 miles per gallon fuel economy on the highway, can reach up to 22 MPG after going through a DPF removal
Note: If your engine does not have a DPF unit, the 6.7 Powerstroke engine replacement cost will also be less. It’s because when getting a new engine, you won’t have to install a new DPF unit.
Why Does Deleting DPF Increase MPG Of 6.7 Powerstroke?
If you delete the DPF from your 6.7 Powerstroke engine, it will not actually increase its fuel-burning efficiency.
Rather, what it does is that it saves the fuel that would have been used to burn out the accumulated contaminants / soots in the DPF filter. In turn, deleting the DPF actually saves some fuel and it relieves the vehicle from additional strain.
As a result, not only will your MPG increase after DPF removal, but your 6.7 Powerstroke engine’s lifespan will be enhanced as well.
Is It Good To Delete DPF?
I, as a veteran mechanic, agree that deleting the DPF is actually better for the vehicle and the engine. It’s because the DPF can easily get clogged when you are constantly on the highway with your vehicle. And, the airflow exhaust process gets disturbed due to the clog.
That’s why having a DPF means putting extra strain on the engine. Especially, if your vehicle is an old one, it is a wise decision to delete the DPF.
Plus, when you remove the DPF unit, the fuel transfer and exhaust flow become smooth and easy. As a result, your engine can easily generate more power and pressure. That means that deleting the DPF boosts up the engine’s power to a higher degree.
Therefore, I think it’s indeed good for the vehicle to go through DPF removal.
Note: Deleting the DPF may also passively help in preventing 6.7 Powerstroke high pressure fuel pump failure symptoms. Such as the low output of power, highly pitched noise, filter damage, slow acceleration, etc.
Is It Safe To Delete DPF To Increase MPG?
It’s completely safe to delete your vehicle’s DPF to increase mileage. However, it’s not safe for the environment at all.
The purpose of a Diesel Particulate Filter-DPF is to filter out the contaminants and harmful particles from the burnt exhaust gas. That means having DPF in the vehicle helps to prevent air pollution.
So, if you remove the DPF from your vehicle, you are not participating in the process of protecting the atmosphere. However, removing the DPF does not bring any harm or negative effect on the vehicle.
What Happens If You Take DPF Out?
If you simply take out the DPF unit from your diesel engine, your car’s Electronic Controlling Unit-ECU will fail to receive the information that a DPF usually provides.
How? well, Wikipedia tells us that a DPF informs the ECU how much particulate soots has been accumulated in the DPF. Also how much back pressure the engine should exhaust. Furthermore, the DPF also provides data to the ECU in order to set the maximum and minimum limit of back pressure.
Now, if you just take out the DPF, the ECU will miss out on these valuable pieces of information. That’s why, after taking out the DPF, you also have to reprogram the ECU to think that the DPF is still attached and in optimal condition.
And this job requires professional-level coding and programming skills. Some professional mechanics use specialized capacitors to trick the ECU into thinking that the DPF is still working. Or, they may replace the ECU with a modified ECU to begin with.
However, this is not a DIY job. So, you have to take professional help to remove your DPF.
Is Deleting 6.7 Powerstroke DPF Worth It?
Deleting the DPF is perfectly worth it (in my opinion). However, depending on how much cost the DPF removal will take, you must decide on this yourself.
You also have to note here that going through a DPF removal is an extremely costly process and it will void the vehicle’s warranty. Plus, DPF removal is not healthy for the atmosphere or the environment. Lastly, if the DPF removal is not done with professional accuracy, you might have to bear additional damage costs.
That’s why you have to factor in all these drawbacks against the benefits before doing the DPF removal. Consequently, you have to reach a conclusion if it’s worth it for you.
Now, if you asked me, I’d say that doing a DPF delete is worth taking the chance. So, go ahead and do it.
people also ask (FAQs)
Here are some of the most asked questions of people who delete DFP and increase the MPG of their vehicle. I hope you will find them helpful.
1. Can I reattach A DPF again in the future after DPF removal?
Yes, a DPF removal does not deprive you of the chance of reattaching the DPF unit in the future again. That means, if you change your mind in the future, you can easily reattach a DPF to your diesel engine if you want to.
2. How long does it take for DPF removal?
Depending on the skills of the automatic mechanic, a DPF delete job might take between 1 to 2 hours, according to Advancedmotorcare. However, this time duration can vary depending on the model and age of your vehicle.
Final Takeaway
Finally, I’d like to give you this final verdict that you should definitely delete the DPA from your diesel engine if your vehicle is an old one. Plus, you may also consider doing it if it’s economically beneficial in your particular condition.
However, if you can deduce that the cost of DPF, removal is not really worth it for you. There’s no need for you to do it. Remember, you’re helping nature if you’re not doing the DPF delete. Best of luck!
