im using on average 16ltr per km according to dash. this is 14mpg approx. i feel this is a bit low? average 413km per tank. i dont stomp on gas. 4.0l engine.

 

i've got the 3.3L 2010 GC SE, which uses more gas than the 4.0L and it seems to be pretty thirst on the city but surprisingly good on highway, never actually calculated it, but i don't think i'm as bad as 16ltr/100kms.

could be the fuel. do u use regular or mid grade? i remember the 4.0L recommends midgrade with regular as "acceptable." or the cold weather in toronto could cause u to burn more fuel.

 

im not sure what normal is. just trying to compare others. usa people seem to post like they in the 24+ mpg so not sure canadians are. im actually using regular fuel. caint afford to use higher.

 

i think my 3.3L is listed at somewhere around 22mpg on the city according to the fuel guide, and considering that the 4.0L gets better economy, 24mpg sounds reasonable.

my guess is that the regular fuel is hurting your economy since the lower octane contains less power that's why they recommend midgrade and consider regular as "acceptable". Do you get any "ping" on regular? if you do, then it's probably the gas. Try running a tank or two with midgrade and see what happens, it might cost u a few extra bucks, but if things don't work out complain to the dealer and see what happens.

your driving habits could hurt fuel consumption too, do you do a lot of stop and go driving or have a heavier foot?

 

with my 3.8l
I get ave 17mpg, when driving in city I got 12mpg, highway with out stops I got 28mpg,

and the ave of 17 I was able to improve to around 19.5mpg over a 3k mile test by driving like grandma and trying to never get the rpms above 2k(which is hard) and coasting alot more, didn't seem quite worth it to me

 

I just look at a 2011 minivan and it is writen 13 mpg to 19 mpg. And that was for a 4.0L engine.

 

Hi , I was getting 21 mpg till it got cold now 17-18 mpg but , I still only have 2,950 miles on the odometer . Lovvorn

 

I just checked the brochure on the 2010 van and it says 23mpg (12.2L/100km) city and 36 mgp (7.9L/100km) highway on the 4.0L. I think the differences between master tech's number and my numbers is because master tech is in USA but DodgeCaravan2010SXT and I are in Canada (Canada uses imperial gallons where 4.4L=1 imperial gallon, the USA uses US gallons where 3.79L=1US gallon according to wikipedia)

So, 14mpg seems pretty bad for DodgeCaravan2010SXT (assuming that your computer is set to measuring in imperial gallons). Maybe your computer is set to US gallons, then it would be reasonable?

Btw. the 2011's still have the 4.0L engine? I thought they were all replaced with the 3.6L Pentastar engine?

 

They have both the 3.6 and the 4.0 with the 62TE transmission.

 

could the brochure have a misprint?

like having it in km per gallon instead of the printed mpg

here is some math, with mpg that seem about right

23km instead of miles would = 14.29mpg
36km instead of miles would = 22.37mpg
