3.0L I6 Hurricane HO Twin Turbo Fuel Octane?

[StuartV]

From what I've seen I don't see many SO's getting better than 17-19mpg on here with more than one trip under their belt.

I'm getting about 18 on highway trips. A buddy just got a new Laramie. He's getting 22 on highway trips.

I get 18mph all day long, not just on certain trips. Though I will be heading to OBX in a few, bet I'm over 20 on that trip. Point is, there is no real MPG benefit to a SO over a HO, other than the HO driver may be a bit more throttle happy.

I am in Morehead City now. I drove here and back 2 weeks ago and then drove here again on Sunday. That is just over 300 miles, each way, from Lexington, SC.

I set my cruise control at 10 MPH over the limit. When I filled up and immediately drove here (the first time) and filled up again as soon as I arrived, I got 18.5 MPG. That is my best, so far.

That is hand calculated. The dash computer lies. It has on every RAM I've owned. And it almost always says I got better mileage than I really did. Like, more than 9 times out of 10 it says higher than what was real.

If you are hand calculating and getting 18, that is awesome. If you are not hand calculating, then you really don't know what you're actually getting.

HO engine in the truck we got seems pretty weak when I called on it. I have a feeling the dealership filled it with 87 octane fuel before we left the lot. I just love dealerships.

We will have to see. I've got a lot of adjustments and add-ons to make it like my wife wants it. Right now, these will include a FlipBack F1 hard bed cover with a gloss black finish. A "bedrug" I will have to cut to fit the RamBox bed. OEM bed divider/extender (used but like new). And some all weather OEM floor mats with the Red Ram Head logos. I might also add some OEM "Red Edition" badging if I can find them. But that's just an idea righ now.

Sticker price was $89,395. But I ended up with about $10,500 in incentives, and about $33,000 for trade in on the 2021 Laramie minus the $10,000 still owed on it. Financed about $56,000 at 3.9% for 72 months.

Payments would be $871.94 if I paid the minimum. I'll likely pay $1,027 per month, which will pay off the note in 60 months if we kept it that long, which we probably won't. I've been making an $800 payment since July 2021 on the Laramie. With inflation, that's about $950. So for about $77 more a month, we've moved up from a Laramie to an extremely nice Level A Limited with almost all the options.

Oh, and I've figured the sales tax and registration at about $3,600 total. That's going to be my only primary out-of-pocket cost right now, except for the extras I described earlier.

All my calcs are by hand. I've documented every tank of gas it has ever had.

That's how I do. Every fill-up goes into Fuelly.

What speed are you driving to get 22 MPG?

I'm thinking it must not be the 70 on slower roads and 80 on Interstates that I'm doing.

Side note:

My '19 Hemi/eTorque averaged 14.1 MPG over the 71,700 miles I had it.

My '21 EcoDiesel averaged 21.5 over the 59,390 miles I had it. Most of that was after installing a GDE tune on it.

Both of those had aftermarket 20" wheels with 275/60-20 all-terrain tires (1" bigger than stock) for most of the logged miles. I estimate those wheels/tires cost me 1 - 1.5 MPG versus stock wheels/tires.

My '25 is too new to say how it really does yet. But, I think I'm probably going to stick with the stock wheels and tire sizes and highway-oriented tires on this one.

Longhorn is a Limited Longhorn

Yes, but it’s a separate model from the Limited. Until a couple years ago it was called Laramie Longhorn. I never understood why Ram didn’t just call it a Longhorn. Maybe they just like to keep people confused. But it is a totally separate model from a Limited.

My commute is 60 miles daily, with speeds around 70-80. Best MGPs are around 70 in this thing.

I consider "Longhorn" as a special options package, much the same way "GT" is treated. But in different years, they limited it to different models.
