Poor gas mileage

[HSKR R/T]

I just talked to an FCA engineer. They told me they programmed the eco light on 3.92 trucks to come on more than 3.21 trucks so you guys won’t fee as bad about having to compensate for being so feminine

It sure what you are talking about. 3.21s are definitely the more dainty feminine gear ratio.

Not to worry. You don't have it broken in yet. With 3.92 gears your eco will stay on more since the truck is not lugging against its own weight. Notice Blet has to be going downhill with a tailwind to have it kick in. Yea, he forgot to mention no passenger older than 6 and no cargo beyond TP (grocery store pack, not Costco)

Searching back through this thread & others, most notice an increase in ECO mode frequency at 5-6,000mi. I'm sitting at 8,700 with zero increase in ECO mode frequency since driving it off the Mark Dodge lot at 11mi. I would have to think it'd be broken in by now unless Ram changed the programming on when to fully unleash ECO mode or possibly dialed it back considerably due to complaints of vibration & noise when it does active.

don’t need gears to prove manhood.

3.21... the gear for folks who cant control themselves

A 3.21 driver doing 80mph+ passing folks just for the sake of being in the front of the line will get worse economy than the 3.92 crowd content on setting the cruise at 70 and enjoying the ride.

Your previous comment says you think otherwise

Enjoy your denial my friend

That's what I just said. You just worded it differently

You guys are slipping. It’s about time this thread turned into a 3.21 vs 3.92 thread. What took you so damn long?

Dammit, we already have a thread for that. Okay, okay, back to gas mileage and how Dodge/RAM has always had crap fuel mileage

Ok, ok, I will refrain from gear ratio references.

But really, I noticed the biggest differences in my truck after 15k. Everything has seemed to settle in and be much more predictable. With 35s and a lift I still see eco quite a bit if I am under 70mph. My problem is that I am not under 70 enough..... my milage is poor by my own choices.

Why would I drive below the speed limit, holding up traffic? But then I don't care about mileage, it gets what it gets.

There are no roads in my entire state that are over 65mph.
Not everyone gets to go 80+ without getting pulled over.

You mean a 3.21 truck cruising at 80mph getting the same mpg a 3.92 trucks getting at 65 mph

You'd get run over in Texas driving 70mph on a highway. I'm in the right lane Dallas to Houston @74mph

With the air slowing him down, the 3.21 doesn't have a chance! so much for refraining

Nah, it's the short legged 3.92 that doesn't have a chance, huffin and puffin at 70 while the 3.21 is cruising while drinking a slurpee asking, you ok bro?
