Just picked up an 18 Platinum with the diesel last week. When I test drove it, the exhaust sounded loud to me, but I had no other F150 diesels to compare it to. As Im reading around the forums and watching videos online, everyone talks about how quiet it is on the highway and how you cant tell its a diesel.

With the truck I've just picked up it has a very noticeable diesel idle (which I dont mind) but a deep, intrusive bass note from the exhaust between 1300 and 1800 rpm, which I do mind, especially on the highway. Additionally, a rattle will come from the exhaust around 1800 rpm when giving it power. I also noticed today when under full acceleration I give out a bit of black diesel smoke.

Finally, my DEF gauge has read as full since I bought it and reads 65,000+ miles to empty. I figure that would have gone down to a realistic number after the first regents but it hasn't moved and I can't tell if it is doing regens.

So my question is; did this truck get deleted? Is there anything I can get under the truck and look for?

Welcome Mike, great to have you here. You have a deleted truck in my opinion. The def gauge is a big giveaway, the other things you mention as well. A non-deleted truck does sound like a gas powered one.

Couple of things to confirm. Check the exhaust tip, a non-deleted truck running properly will be very clean inside while a deleted one may show some signs of soot. Look underneath and you will see all the factory hardware on the exhaust pipe while many deleted trucks have a fairly straight pipe and muffler. Under the hood you may notice the egr cooler and valve is either missing and blocked off or just unplugged.

Also if you are a forscan guy you will want to do the list of forscan mods, see jmperlik's excellent thread Here

Ask any questions and let us know more about your new toy! Congratulations on becoming a diesel F150 owner.

Sure sounds like it then. The inside of the exhaust tip is indeed sooty, and the pipe looks like its just a straight pipe with the typical muffler box towards the end. I'm only getting about 25mpg indicated, haven't had a chance to do a hand calculated fill up yet. Shouldn't I be getting better mpg from a delete?

Anything I should watch out for with a deleted truck? I was thinking about getting it done when it hit 100k but looks like I got it early.

I can't help on the fuel mileage question but 25mpg for a 6,000 pound truck is awesome, isn't it.

I can't tell you much about a deleted truck and there isn't much on the internet about them either. Given the choice between a fully compliant truck and a deleted one I would personally prefer a deleted one.

 

[mikediesel]

It'll definitely help the longevity of the engine from what I understand. The only thing I'd change is that bass note at highway speeds

 

[Dunrollin]

We had a deleted member here or on another forum and he added a resonator that seemed to solve that. A search didn't turn it up on this site.

@mikediesel, you’re a lucky dude. Enjoy that thing.

I purchased my 2018 F150 PowerStroke 21,000 miles ago - I reset the 2nd trip monitor to zero when I drove it off the lot and only reset the 1st trip monitor when I get fuel, always leaving the 2nd one alone to continue counting... my combined mileage over those 21,000 miles is 22.5mpg. My best mileage ever came on a drive to St. Louis where I set cruise control at 70mph and let it ride, got 30.3mpg driving there and back (approx. 400 miles).

25mpg doesn't sound bad at all, depends on your breakdown (city/freeway). Might try resetting a trip monitor and then leave that one alone from now on so it can reflect performance over the life of your truck ownership. I'd be happy to get to 25mpg. That's 10% better than what I get now and my truck is bone stock.

Also if you have bigger than stock tires and new metrics weren't entered in Forscan your mileage and speed will be off a little.

 

[mikediesel]

Glad to hear you get that kind of mileage on highway trips Bandit. Part of the reason for getting the diesel was good mileage on long family trips.

Thankfully I've got stick tires and suspension, so I don't need to worry about any of those adjustments.

I'm taking it in to a shop in a couple weeks to add a resonator, we'll see how it sounds after that. Now I just need to find a way to figure out if its has a tune already and what that tune might be.

Post a pic of the exhaust system under the passenger door, I can tell you real quick. Also check is the EGR and Throttle Body is unplugged under the hood.
