I was getting around 29-30 mpg on the highway with best as 31.4 mpg. I got transmission replaced (within warranty) 2 months back . Now i am getting 22-24 mpg .

Same driver, same driving style and same route ( ~40 miles commute (M-F)) , only change is the transmission.

Any idea what could be wrong? car is driving smooth.

Possible that the transmission will "break in" over the next few months and the mileage will continue to improve. However, I'd suggest keeping a written record of fuel consumption/distance traveled/driving conditions as evidence against a claim with Nissan

Thanks KBrian.
When you say written record, do you mean fuel receipts along with the miles written manually on them ? or is there a good way to keep records?

I can already tell you that Nissan will say that your mileage is within the acceptable range.
may be Yes Halwg, but i was pampered with excellent fuel economy earlier hence the whining;).. On a serious note , i am just worried that mpg won't deteriorate further.

First gen only get 24 hiway tops. I am not sure if the newer MO is rated for more but it can't be too far from it.

I just swapped out my odyssey transmission with a reman at home and after 2 tank full of gas used, its mpg is the same as before. I don't know why you are getting less. How long have you been observing this since the replacement?

For most of my vehicle ownership life, I have kept a vehicle log. While it is arranged to record fuel fillups and distance driven, I include service and repairs as well. I do maintain the factory service booklet that came with my Murano (we have an included maintenance contract with the dealer) but I like having a record of all vehicle activity in one place.

I bought a bunch of cheap, small, bound, lined notebooks a while ago, and I made some columns to record date, location, amount and cost of fuel, distance on that fillup and total distance driven. I also keep track of tire changovers and rotations this way. I sell my vehicles privately usually, and this satisfies buyers' questions about service and repair as well as fuel economy/cost of operation.

I hate a junky glovebox, so this method of record keeping allows me to keep all the service/repair paperwork at home.

Going to your dealer with a history of fuel or oil consumption will mitigate any argument that "its within factory spec" if the record shows a noticeable change in performance over a small time period.

Hope this helps

If your car is within the factory spec on mileage, your records don't matter. It simply IS within specs.

I think the situation is unusual, but you're getting good mileage as is.

Yeah, sounds kind of weird that it would drop. On the other hand, thats about the same milage I get on the highway.

You were right Brian, looks like the new transmission got matured and mileage is much improved now. I started getting close to 28-29 MPG on my same office route:)
