Real 2010 3.7 MPG

Hey all,

Graduating college in the next month or so and I have to purchase my first vehicle. Family has had Jeeps throughout my life and I've learned to love them.

However, one major issue. My commute to work alone will be about 20k miles/year. However, 90% of this commute will be on 60-70 mph highways.

I'm looking into a certified pre-owned 2010 3.7 Laredo with about 30k miles.

Can all of you with 2008-2010 3.7s tell me what MPG your looking at? And what your city/highway split is?

I'm HOPING to be looking at 18-20 if I drive this 90/10 highway/city split...I would really like to tackle winters with 4x4.

Appreciate it,

jagj

I don't have a 3.7 but looking on Fuelly.com I see 2 2010 3.7's getting 18.9MPG and the other 25.6MPG. If these numbers are correct I would think with your highway mileage you would be in that ballpark.

With all my mods I average 15 MPG in the city. If I set my cruise control at 55 mph I can get it up to 22-23 MPG highway

Yes, I looked at that. But there are only a handful of 3.7s on there and they don't seem to reliable to me (based on # of fill ups, mpg, etc.) Thank you though.

Thank you. I'm not too familiar with all mods - do you have any that impact your MPG?

The Fastman Throttle Body & CAI adds to performance but then it also added to your lead foot too. Might want to look into a Hypertech, it's the only tuner available for the 3.7L. I got the Max Energy. None of these things are really noticeable by themselves but together you notice a difference.

As far as getting good gas mileage, just make sure your plugs are good, filters clean, and fluid is fresh.

Ya, from what I heard about reliability, I'll be going the certified pre-owned route - so I don't think I will be adding mods until it expires to make sure not to void the warranty. So, it will be stock for long bit.

I have a 2009 and on the highway driving at 80mph I get about 20MPG's. In bumper to bumper highway traffic/city mix it drops down to about 14.5mpg. I did notice when I put my Grille Guard on, I got about a 1 MPG loss. I also have a pretty heavy foot at times.

I have been able to get better mileage (22mpg's) with careful driving, keeping the Jeep under 60mph, no sudden moves or mashing the gas and keeping the RPM's down.


I just signed up on Fuelly.com so I will manually calculate MPG's to add some more sample points to the statistics.

Bone stock 08 3.7 I get any where from 17-21 on my commute. 90 miles each way 95% highway (70-75MPH). It does pretty good as long as I stay under 80 and there not any kind of a head wind. This is also with winter blend gas. I don't think we have switched back yet. This summer I'll prob add a Fastman and Hypertec tune and see what happens.

I've seen up to 25 on back roads at 50-60

It is listed for 19k. Although, it is certified.

I have a 2010 Laredo, stock with 3.7l. I avg 20mpg highway and 17 city. During long highway trips, I've averaged 23mpg!

Butterjeep... I bought mine last August for $17,300 with 38k miles.

I'm about to do some mods, 2" RRO lift, 265/70-17 tires, Hypertech Max Energy, K&N air intake, and now looking at Fastman TB
