2025 Ram 1500 High Output I6 Needs Premium Fuel, Like All Performance Engines
The switch to a smaller engine with forced induction was never about cheaper ownership—it's a push for more performance and lower emissions.

I believe that was due to the high option trim levels the HO is tied to more than a statement about the motor. I saw that thread in the 5thgenram forums and that fact was largely glossed over by the people upset about it.The SST HO has less payload and towing than the standard output SST... not sure why one would opt for the high output anyway.
I have the same thought process vis a vis repair-ability etc. I buy used and maintain my own vehicles as much as I can. For me the issue with the WK series now is parts availability. That will be the main thing pushing me to a newer vehicle. Just watched an episode of South Main Auto. Eric O needed a new FCM for an 09 WK. Of course NLA, discontinued. Found used but he had to sent it out to a specialist to get it coded to the vehicles VIN. He could not do it with his full featured scanner system. Point being they discontinue parts but also make it hard for a DIY to repair with used parts.Vehicles aren't ever going to get simpler. Heck, there are still people complaining about Lean Burn ...
Engineering has taken a back seat to marketing and cost-cutting at Chrysler, but that just follows the trend started by Daimler.
Whether they had kept the hemi or with the new Hurricane, my big concerns would be: Purchase price, parts support and cost, ease of maintenance and cost, and warranty support.
I'd bet dollars to donuts that I'm not alone here, as I'll be keeping my 3.7 WK until she blows up, and then - maybe - I'll take a look at a 3.6 WD.
I'm putting midgrade in my Grand Cherokee Trailhawk and it makes a positive difference in both MPG and power. YMMVThere's a difference between recommended and required. I promise you almost nobody is putting mid-grade in a 5.7 Hemi truck.
Is that the hill you're really gonna die on? They've been routing the exhaust under the trans for a while with a cat right beside it as well. A cat is the most efficient the faster is warms up which means it is going to be right there no matter the engine configuration. If anything the tt i6 cats are better suited for the transmission as they look further away from it (at least one) and the transmission isn't being sandwiched by them.The V8 Ram 1500 Is Dead After 2024 | The Drive
not sure if the pic will show up in the link but I see a few things here I do not like.
1) all the heat generating components are on the same side of the engine, both turbos, and cat converters
2) exhaust pipes appear to snake under the trans pan, if that's the case let's hope that "lifetime" fluid is really lifetime
3) the article quotes a couple more MPG than the V8.
all this for that, and they did this engine instead of re-designing the cyl heads on the V8 to make it better on emissions? An all aluminum smaller displacement V8 with MDS which works just fine on most Hemis, would have done the job for far less expense.

If these engines only make 100K miles with no issues it's a rip-off, especially considering the price premium these trucks command. And I bet 100K is probably about what they'll last, too.He mentioned it himself, this is the most power per liter they've ever mass produced. It will be very interesting to see how it holds up when it's got a 12k lb. camper behind it on a 100 degree day climbing the mountains. If these engines can make 100k miles with no issues in the full size pickup truck lineup I will be impressed. But for the time being I am skeptical.
Are these alleged reliability issues for BMW directly traceable to hot exhaust near a transmission? If not, then this is irrelevant.Modern BMWs aren't exactly reliable, and that exhaust setup has to be one of the dumbest most complicated ways to route the exhaust I have seen. I bet they use a proprietary 10.5mm 9 point star bolt too.
I mean seriously how important is weight distribution to have the exhaust cross over 12 inches forward? It's miniscule at best while having a hot pipe that is squished and has sharp turns blocking access to the transmission.
To be clear, ONLY the high output 540hp hurricane requires premium. The standard output requires minimum 87
More infoBeat me to it. I think the thread title should include "High Output".
<edit> I see it has changed now.
but we all also know that it's not just engineers involved in design, it's the "make it cheaper guys" who have a way of mucking things up.Because everyone here knows more than the engineers who designed the engine….![]()
True. However, let’s see them in actual use over time before passing judgement on how good or bad they are.but we all also know that it's not just engineers involved in design, it's the "make it cheaper guys" who have a way of mucking things up.
the rest of us non-engineers just see the end result and are stuck with fixing it.
They might as well have kept the hemis I'm not selling my heavy truck it'll still be cheaper to operateYepp
Just like the ecoboost
When is Dave going to address the absolute cratering of Ram 1500 sales since 2019, or is that also a nothing burger?More info

Ram 1500 “premium controversy” is a nothing-burger
Recently, another site came out with criticism that the 2025 Ram 1500’s high output Hurricane six will require premium fuel. This was their second headline; originally they didn’t mention that it was only the high output engine requiring premium. This was followed by predictable comments from...www.stellpower.com
