pulled the 5er little over 500 miles this weekend visiting family averaged 7.1mpg sure hoping this truck improves a little on mpg. It has 28000 miles on it now and i never broke 3grand 90 percent of the time was sitting on 21 or 2200

anybody else pulling around 9500# pluse or minus with a newer 3valve and 4:10 gears ?

i think im really starting to miss my 460 it got 10 mpg hot or cold heavy or light with 4:10's

 

That is good mileage. I pull 10,000# TT with my V-10 Dodge & get 5-6.5mpg @ 70 mph. I seldom pull flat terrain most of mine is from 500 ft to 8000 ft of elevation.
I doubt you will see any better.

 

I'd say that was pretty good. 5er's have a big front and that really blocks the wind.

 

thanks for the input guys, have to admit i sure hoped id get 10 out of her like my old 460 but i guess when 10 mouths are open they need fed cant say ive yet to be disappointed with power just wish fuel was a little better
i may have to do some reading on here to see what other mods guys have done but to my knowledge everyone ive talk to local hasnt seen any improvement with exhaust or cold air intake upgrades let me know if any of you have seen the shining light with the bolt ons

 

I have upgraded my exhaust on my Dodge V-10 & it helped the power but not the gas mileage. Remember one thing most computer vehicles get way more air than they can use with the stock induction system in a stock version. Cold air intakes are a waste of money on a stock vehicle in my opinion. I have a friend that has tuned for racers does a bunch of flow testing, what I tell you comes from him. Maybe chipping the computer might help. Driving 30 mph will help also. You have weight, rolling resistance, wind resistance, that continually work against you.
We all want better mileage, But you are doing good compared to most.

thanks man on the complement ill have to waite for warrenty to run out before i do anything i see 5star seems to be popular on here might check into that and 30 no thanks lol

 

Try towing using more RPM's. You take these V10's well over 4000 RPM's and it won't hurt them. Oh, for tuners call Mike at 5 star.

 

I also get that mileage with mine. Old saying is "if you want horses you gotta feed them".

As far as a tuner? Please spend some time at this site. Contact Mike if you have questions. He will help wake up your V10.

thanks for the input guys once my warrenty is up ill check out 5star, Spud57 have you had a tune done what kind of gains and or differences did you see

 

My 99 crew cab dually V10 with 3.73 gears gets 7.5 pulling 7000 lbs of travel trailer.

 

well mayby i shouldnt holler to loud then, just comparing to my old 460 i was hoping to get the same or better but cant have it all i reckon thanks for the input jerem0621

 

Just thank the EPA .....

 

thank you Extra Pathetic Agency

 

Unfortunately I don't have their tune. It is on my bucket list. Many on this site have and are really happy with the results.

Check the sticky 5star tune under the V10 forum.

 

I tow a 9000# TT.

I can normally set my watch to 8mpg...BUT...(big but)...when I get the 10% ethanol blended fuel...I drop to mid 7's guaranteed!...

I will pay $0.10 extra for the lower octane ethanol free stuff to keep the mpgs up a little.

Wind is your enemy when it is coming at you too.

We just got back from a near 5000 mile trek...averaged right around 8 over the whole trip...but some tanks were slightly higher and some slightly lower...

Ethalol is NOT our answer...it has ~72% of the energy in a gallon as compared to a gallon of petrol so that equates to burning MORE fuel at less mpgs and burning our food...make a lot of sense...to someone...but not me...
