Subject: 318 vs 360 mpg and offroading!!!
IP: Logged

Message:
My 93 Dakota 318 is coming to its end, and it is time to start thinking what is the best way for me to go.
My style of driving for this truck is mainly offroading/rock crawling and a little bit highway. My tires are 33s mabye one day 35s.

Fuel milage is a concern to me, being that most of my trip are easy over 500miles.

Any tips/hints one what engine and parts to use would be great...

Thanks

i have the 318 and get 15.9mpg the 360 gets 13.2mpg thats in dakotas. i take my truck off roading alot and its got great power and great low end torque. i think in your case i might just go with the 360. you could get close to or maybe better gas mileage. there both great motors and have great power but the 360 has a egde with 20 more hp and 35 foot pounds more torque.

I've got a 2000 Quad Cab with the 360. While towing my pop-up trailer (3000 lbs) at 65 - 70 mph, I was getting about 15 mpg. Non-towing on a trip to and from Montana (600 miles each way) doing 70 - 75 for the entire trip, my mileage was between 17.5 and 19 mpg.

Recent mixed city/highway driving the truck's been getting about 15.5 mpg, but I just changed tires so I'll have to try a couple more tanks of gas for a better idea with them.

Hey, ever lose a muffler? After taking mine off and straight piping
it, I gained a little bit.. after my straightpipe rotted out, Gotta love
Upstate New York, I took off the tailpipe and gained 40 miles per
tank! Course I have to wear earplugs when on the thruway and I
lost a considerable amount of torque. but my Horsepower
increased a total of 20 and my 318 4WD 94 Dakota jumped to
almost 19 MPG... Pretty sweet if you ask me. It will be a sad day
when I put a flowmaster on it.

acidman, you might want to do your math over again. the 360 dakotas got sh!tty gas mileage all around. ive never heard of one getting the mileage your gettting 12mpg around town is the best ive seen with any 360 powered vehicle.

I check my mileage with every fill-up, dividing mileage travelled by gallons pumped in. I'm quite strange about that.

One thing I've noted however, is that the on-board computer in the overhead console can be off my as much as 1.5 mpg or so on the average fuel economy.

My driving style may have something to do with it though. I don't stomp on it when starting from a stop, and I use the cruise control as much as possible. Granted, the time I got 19 mpg was between Idaho Falls, ID and Bozeman, MT. The section of road between West Yellowstone and Bozeman has about 75 to 90 miles where you're going downhill along the Gallatin River. Beautiful drive that I'd recommend to anyone...

acidman-- Yep-- I can attest to that. I now live in Bozeman and love it here... that's a great drive. I've done it several times, the only bad thing is wildlife jumpin out in front of you and having such small rotors on the dak. A bit daunting at times I'll admit.

if the 360 got this mileage, there would be no point in having the 318. everyone i knew that had a 360 has always gotten sh!tty gas mileage. unless your special, which i doubt, your probably not doing your math right. or you just want to make yourself feel better about having a gas pig by saying it isnt. i call bs on acid man saying this:

maybe you were getting 15 towing your pop-up
but noone gets better mileage going 70-75, rather than 65-70. everyone knows a vehicle gets the best mileage around 55.

Wow. I'm having my math skills challenged by someone who can't even write a sentence that's punctuated correctly. That's rich, not to mention insulting. You may want to recheck your younger sibling's elementary school english book for some assistance, because your high school book won't be covering the basics that you need.

For the record, it isn't that hard to divide number of miles traveled by the number of gallons put into the tank. It's simple division with an easy answer. The trip odometer gets reset with every fill-up, and the mileage gets checked with every fill-up.

As an example: 256.3 miles (combined city/highway) divided by 17.136 gallons pumped equals 14.96 miles per gallon.

Can I explain why my truck got exceptional mileage? Nope. It will remain a mystery. But I do know for a fact that the math was correct. As I stated before, I'm not one to shove the gas pedal through the floor on every start from stop. I've changed the engine over to synthetic motor oil, and I've got the K&N high flow air filter/intake set up. Those two things, combined with a conservative driving style have surely added a bit to the mileage.

Sorry if you can't accept the facts, but that would be a personal problem.

My 2 cents ... go with the 318 or 5.2. It has less torque and horsepower. The torque is more consistent over the total rpm range. If you are going to hotrod your motor, the 360 would be better.You should be pretty happy either way.

I have a 4.7 4x4 RC and what i have found is that it all dependes on how you drive. For instance, The same 110 mile trip down Bluegrass Pkwy I make about once a month I have gotten as low as 16.1 MPG , however, as high as 22.2 MPG.
Of Course when I got 22.2 I was driving 60 mph with the tailgate down, air off, and just changed air filter and checked the air in the tires. Also, it helps a bit if before a big hill you turn cruise off and slowly start picking up speed so at the bottom you will be going fast and can let off some until you get to the top. When you do it in cruise it likes to jump up to about 25000rpm.
