Re: Towing and fuel economy 3.6L not acceptable

Green, do you mean the left-right toggle on the stick when it's in the D position? That's called ERS - Electronic Range Selection. It just limits top gear -- you can read about it in the manual on page 379 I think.

Doesn't matter. The point is is that you can hold each gear to get the best pulling power (ie. about to go up a steep hill) and can have it shift into 5th as per the OP statement. The tow/haul button is useless if you can pick out the gears you want to use. Plus the ERS has the same set up as the autostick based on the autostick in my moms old Nitro and the WK2 V6 that I had to drive around.

Re: Towing and fuel economy 3.6L not acceptable

The tow/haul button is NOT useless, you've got no idea!

The button alters the shift parameters in the box, alters how long it holds a gear for, and much more besides......

Tow/Haul makes an enormous difference, and on a recent 3000 mile round trip in my WK Hemi, towing 5500lbs, it made a improvement of around 1.5 miles/gallon (IN tow/haul).

You saved 1.5 MPG using the tow/haul button vs using what? The autostick or just leaving it in drive? The things that you said about the tow/haul button is something that you could have did with the autostick. You can shift the gear when you feel that you no longer need that gear and you can hold that gear longer. For those of us who don't have an autostick but have a tow/haul button (like me) the button is useful.

Re: Towing and fuel economy 3.6L not acceptable

You're gonna drive 3000 miles manually shifting an automatic transmission when you could simply press a button and have a pre-programmed shift protocol optimised for towing loads?

Stop it.

Re: Towing and fuel economy 3.6L not acceptable

Saved 1.5mpg by using Tow/Haul and leaving in D as opposed to no Tow/Haul and in D.

Your argument will be that there's more gain to be had using manual gear selection via the +/-.... I say bullshit, and all you'll do is hold gears too long.

Re: Towing and fuel economy 3.6L not acceptable

Back to the original topic, I think there's too many variables in the OP's description.

I'd like a pic of said trailer attached to the Jeep.

Also, was there a headwind? I've experienced outrageous fuel consumption doe to headwinds that you just don't notice from within a modern vehicle, with the exception of your fuel gauge going down like someone's stabbed your tank with a knife!

Re: Towing and fuel economy 3.6L not acceptable

All good comments....just to clarify the V6 does not have a tow/haul button. I will send pics of the trailer etc when I am back in town on Friday.

I guess coming from a diesel to the V6 was a huge change for me and I need to get used to it. I only trailer 5-6 times a year so I felt the V8 was overkill for me.


Thanks for all the great input.

Re: Towing and fuel economy 3.6L not acceptable

I just drove 1000 miles through the Appalachians towing a 4000 lb Uhaul trailer averaging about 12 mpg. I made it a game with the fuel economy meter to try to keep it as high as possible.

Re: Towing and fuel economy 3.6L not acceptable

I don't tow but when you do, I don't think V6's do much better than the V8's.
My brother has a Honda Ridgeline, 3.5L, and when he tows his S2000, he gets only 9 mpg. That however is through hilly terrain...southern California.

BTW, an easy conversion from L/100km to MPG (US): 235.5 divided by your L/100km.
(for Imperial gallons, the conversion number is 282.5)

Re: Towing and fuel economy 3.6L not acceptable

Should have kept the diesel, you would have had the towing power of the Hemi and the great mileage to go with it. although diesel is 5 -7 cents a litre cheaper then regular gas in Canada, in the usa its like 20 cents a gallon more the regular.
