With 4.30 gears you must be ready at any given moment for peak torque even if not needed.

 

I get 18 mpg, sometimes a little more, cruising at 70mph with the motor spinning at 1600 RPM. There is PLENTY of torque to maintaining speed on flat and even slightly uphill situations even with a little headwind. Always spinning at 2100 RPM is just wasteful on the non towing trips. If your trucks needs 2100 RPM just to maintain 70mph on the freeway when not towing, you need to get it checked out because something has gone very wrong.

Now why does someone buying a 3/4 ton care about MPG when not towing? because I use it for work, and I don't get paid for miles that don't carry cargo, but I still have to get there to get it. That's the same reason why professionals sometimes stick to the smallest tires possible, every penny counts in this day and age trying to make a living. My work has gotten tough enough in my region that I am gradually shifting away from what I do now and pretty soon may not need a 3/4 ton anymore. Y'all balling with your 35s just to commute can do that but you are not getting 18-19mpg at 70mph running 35s and 4.30, but if that's how you choose to spend your hard earned money, who am I to say don't do it.

If someone is towing 10k+ 100% of the time, sure, go ahead and get 4.30, I will be the first one that recommends you to get the lowest gearing you can. But I highly doubt anyone here is towing that much every mile the truck is in motion.

 

here here! That's what I was trying to say. My Jeep Cherokee is 1600 rpm's at 70mph and it too has a tow package. Obviously not as much capacity as the f250

 

It boggles the mind that Ford spends all this time and effort to produce a pushrod motor that generates something like 80% of its max torque at 1500 rpm, yet some buyers insist to run it at at least 2100 rpm at all times for...reasons.

 

For me I can never have too much money, a girl too pretty, a car/motorcycle/truck too fast/powerful, so on and so forth. I want more power, not less. Marginally better gas mileage isn’t something I’m consider about.

 

Less power and more MPG is the new thing for 8,000lb trucks these days. Geeze,..get with it! They can't afford an extra $4 per fillup after buying their ultimate platinum limited diamond edition

 

people who run businesses care about operating cost. It may be an alien concept to some, but believe it or not, some buyers buy SDs not as a commuter or weekend toy tower, but to make a living with.

 

….yet you are driving around in a gas truck that is significantly slower and less powerful than a power stroke. so you have just enough extra scratch to blow on gasoline, but not enough to buy yourself a diesel? That’s a strange financial success niche you fit in.

 

he’s going to parrot some stuff about how the 7.3 is the second coming of Jesus but you’re right. The real reason he doesn’t have a diesel is the cost. Plus he tows a 2500lb trailer and doesn’t need one. He doesn’t even need a super duty at all. He should really be in a 150 but he (the one who preaches to diesel guys about not needing diesel) doesn’t even need a super duty at all.

he’s full of this sort of backwards crap when you try to understand his logic.

 

now I’m most curious how he will explain his aversion to diesels after his Marvin Gaye “Ain't No Mountain High Enough” style speech about power and girls.

You make a valid point, it was simply projection when he was telling people like me who actually use trucks for a living to buy a half ton if we don’t get 4.30 gears.

 

What a worthless thread.

 

Then your input is even less than worthless.

 

That is false, every diesel truck almost is like that.

 

Your not averaging 18-19 MPG hand calculated on the highway, our 2wd single cab with 3.55s didn't even get that, the digital readout doesn't mean anything. Running at more RPM along with the torque advantage of lower gears means it takes less throttle input to go the same speed which can get you better fuel mileage in some cases. More RPM= more fuel used is only true if the throttle input is the same for both, which it often isn't, what is more important is where the engine makes it's peak torque.

 

Another false number pulled out of nowhere. Remember just because you don't own a 4.30 geared truck doesn't mean they aren't better.
