Hope I'm on the right page here. Anyway looking at a 98 Ram 4x4 2500 Ext Cab, Long Box. This is the 5.9, 12 Valve one. My question is comparing the 12 Valve, to the 24 Valve. Which is the better of the 2? I pull a 22 ft. car Hauler, and run the Mid West, about 3 times a year, and am looking for both Fuel Economy and Power. This is over the present 5.2 that I currently have. As some of you know the winds on the Prairies can play hell with a under powered Truck. I am on here asmost of you know your Trucks, and I'm not trying to cause havoc, just that I know the 12 Vs the 24 Valve has its ups and downs.
So if you guys could give me some insights, it sure would be appreciated, and thank you all.

 

Hows the price on that truck? That combo, the 12 valve in the 98 is pretty sought after because of the reliability of the 12 Valve injector pump and because it has the updated interior.

 

Looking some where in the $10 K figure.

 

You'll be looking at the 12v then.

 

There is another question I have and that is the mixes that I have read about about additives, to the Fuel.
I got the MMO, as Marvel, but the PS, and others can't for some reason to get the drift of these. I used to line haul a few years back, and did the Auto Trans Fluid mix, and the Methyl to prevent the Fuel Gel.
Am I close in guessing thats what these terms are. Would sure like to know what works, again thanks.

 

I stopped running the MMO a while back for a number of reasons. Lately I've been going back and forth with Howes and PSD (Power Service Diesel). The PSD comes in two flavors: one is just a fuel additive/cetane booster and lube enhancer, the other is all that plus anti-gel. From my (admittedly limited) experience, I think the Howes lubes a little better and from what I hear from OTR guys, it's a better anti-gel. But either would be fine.

And to your initial question... I've never driven an older 24V, but I love my 12V. Power, torque, mileage, I've got it all. I can't see you going wrong with either one.

 

Many people stopped using MMO because of the solvents in it. In one test, it was shown that it lowered the lubricity of the fuel below just the fuel alone. I run a mix of two stroke and power service. The 12 valve is a great million mile engine.

 

Seems that I'm getting a lot of good info here and sure appreciate it. I to have heard a lot of good vibes on the 12 V, and am leaning in that direction, more and more. These additives are they used in each tank of Fuel or just how often? Also this anti-gel additive is used only in the winter, like I mentioned earlier we used Methyl, in our trucks as they had open exposed return lies and the Fuel would Gel in them.
Sitting on the side of the road in below zero temps isn't exactly a good past time, non the less it has happened to me, but only the one time.

 

I generally run an additive of some sort in every tank. Back when I did the "Drew's Brew" (search this site for more info), I used the PSD regular for most of the year and the anti-gel version in winter. Now that I'm leaning more towards Howes, I just run it all the time. Although I'm thinking of adding a little two-stroke after hearing a bunch of guys here talking about it...

 

I should add that the reason for my wanting to add two-stroke to the mix is this new ULSD fuel we have to deal with. It just doesn't lube as well as the old stuff, and I want to keep that injection pump lubed as much as possible.
