MPG Test - Regen vs No-regen

So, I decided to do a little test and finally it worked out exactly how I wanted when I filled up. I drove the same exact route (just 70 miles though), kept everything the exact same as I could and was hoping to have one route with a regen and one without. Finally it happend. I filled up just like I normally do (round up to the next nearest gallon), at the exact same pump and kept my driving habits exactly the same, just 1 day apart (one trip on the 16th and the next one was today on the 17th. I filled up, drove 70 miles with no regen, filled up again, drove 70 miles and it went into regen during the trip, so I filled up at the exact same spot as I passed by the day before. It was about as near as perfect as a test you could do I think, lol.

Truck is a 2008 Job 1, Extended Cab SWB, 4x4, 3.73 Gears, bone stock.

No regen:
69.4 miles, 5 gallons (clicked off at 4.4 gallon) = 13.88 MPG (or 15.77mpg when it clicked off)

Regen:
70.1 miles, 7 gallons (clicked off at 6.3 gallon) = 10.01 MPG (or 11.13mpg when it clicked off)

Either way it doesn't really matter which way you look at it. That right there shows you EXACTLY what kind of difference these DPF's make in our trucks. Basically 2 gallons of fuel was injected into the exhaust to burn off, WAY TO GO EPA!!! Too bad you can't take these stupid things off. Maybe one day they will realize what they are doing and let us take these things off legally and without voiding warranty and giving us a $10,000 fine. Yeah, yeah I know.......

Anyways, just figured I would share that tid bit of info. Some may find it interesting.

I found that I had a new truck after I did my DPF/CAT delete, and installed my Spartan system. The EPA can kiss my ***. It's all about money anyways, how is it "environmentally friendly" to burn damn near twice as much fuel to meet emissions

Running Spartan Tunes AFE PG 7, Flo Pro 4" DP Back, thanks to Cobb's Diesel. It has been great so far.

diselkane...Your statement about the EPA is how the drug dealers feel about not being able to sell their illegal stuff. I guess you feel that you have the right to pick and choose which laws you are going to follow. So let's see; I don't like the speed limit so it's okay to drive as fast as I want, I like to drink so it's okay to drive drunk, I think my neighbors dog is too loud so it's okay to shoot it, etc. I too don't like some of the laws in this country but I'm sure not going to knowingly violate them. If we all did as we want this country would be in a bigger mess then it is. Just my thoughts. Go HUSKIES!!!

The mpg is gonna be a lot closer and a far less significant drop after the rest of the tank is burned. Because you only did about 70 miles the results are kinda skewed. Interesting to learn that it burnedd about 2 gallons through regen.

I'm curious to see what would have a larger carbon footprint per year...a 7.3 or 6.4? Both of the same cab and bed configurations. Even with my lift i can still manage 19 highway in the summer. I don't think i've ever seen a stock 6.4 hit 19...especially not one with a lift.
