BuzGuy Posted July 2, 2014 Understand there are ways to improve fuel economy on the V8 NV3500 version so can anyone tell me what to buy to do this? Also, my owner's manual sez I can call up the avg MPG on the speedo screen by using the left side speedo screen knob. It does not come up... I do get the miles traveled and avg speed but not the avg mpg???? Why would this feature "AVG MPG" be in the owner's manual if it does not exist... what am I doing wrong? Was anybody else able to get this feature working? I love this feature on my Honda van and I was looking fwd to seeing it on the new van.Thanks,BuzGuy at Harveys Lake, PA Quote Share this post Link to post Share on other sites
nutekit Posted July 7, 2014 Unfortunately they disabled this MPG display in the newer vans. The first production of the van had this feature. We purchased a scan gauge to display the MPGs. You can also purchase several different blue tooth enabled OBD sensors that will sync to your android and / or iPhone and give you the readings as well.

Hawkeye77 Posted July 15, 2014 @BuzGuy, Try the Air Raid CAI for better airflow. I put one on my van last Week, and am data logging my MPG via Dash Command and my OBD II reader. I wil post results as I log more miles. 2 lmorten1 and GrowingFamily reacted to this Quote Share this post Link to post Share on other sites
GrowingFamily Posted October 1, 2015 @Hawkeye77 Did the Air Raid CAI help at all? Thanks for updating! Quote Share this post Link to post Share on other sites
ASD Dad Posted October 2, 2015 I did a review on the Airaid MXP on this site, I lost mpg! That was babying it too and it's happened to other Nissan 5.6 owners. It's not common but I don't think anyone has ever gained mpg. You do gain horsepower. 1 GrowingFamily reacted to this Quote Share this post Link to post Share on other sites

I think they removed it because they thought they'd have a hard time selling the vans with it showing 13 mpg. Quote Share this post Link to post Share on other sites

I see a bunch out there and I am not that mechanically inclined. These seem awesome though that you can monitor things on your phone.
