What mpg could an 05 610 cruising at 25mph get. I live in a town where you can usually just cruise along without a lot of stop and go. I've never heard what kind of mileage you can get going slow.

 

Try it and let us know.

 

I get 16.5-17.5 with my 6spd when stuck in traffic like that. Of course I try to keep the RPM over a grand to keep from having an issue with Dodge over idle time.

 

That is a new one. I've never heard that question before. My only suggestion for you is to make sure you have good glass insurance!!! There are a lot of people out there that probably wont appreciate following you at the slower speeds.
I doubt if the mileage will be very high. The most fuel efficient speeds are from 40 to 55 mph, depending on vehicle, weight and gear ratios.

 

I tried something like that with the overhead computer running 45mph for a long stretch of road. Indicated 27mpg. Just don't know how accurate the computer is at that speed.

Drive that slow here in Austin and folks will blow right by you, probably waiving with one finger.

 

Mine shows about 26+ as well doing that - for the short times I was able to do it.

While idling in 6th gear, my truck will easily do 25 mph - probably faster because its too fast in the neighborhood. It will easily accelerate from that speed too, so its not lugging.

 

... with my auto have to be doing 50 mph to get the best mileage... you guys with manual are so lucky
