Just wondering if anybody tried one of those performance chips that plug into the OBD2 port? If so did it increase the MPG?

Thanks

All it will do is encourage you to get on it more often and burn more fuel. Whatever mileage you get now is what you’ll get after or less. If Nissan could get a higher average they’d do it from the factory as a sales tool.

I agree. Its a heavy truck running a larger normally aspirated motor with old school hydralic steering that takes at least 1 MPG. Like the second gen there are no magical mods that can rectify this. If the data on fuelly.com are accurate then the increased MPG's is less then 1 MPG on the third gen. I think emissions is better and the extra gears might deliver better mid band torque. But if Nissan was trying to gain noticeable gains in mileage I think they failed miserably.

If you want better mileage, slow down. Cheap plug-in dongles off FleaBay or scAmazon aren’t gonna do anything but lighten your wallet.

But/and the dash readout tells an even bigger lie in the Gen 3s for those who'd choose to believe it.
Owners just need to DO THE MATH over 10 tanks for some practical truth. Jethro Bodine calls it ciphering!!

Really who needs plug in dongles when folks on here are reporting (so far) 30mpg in the gen 3's.

You'll drive yourself nuts worrying about gas mileage. I gave up tracking it several years ago.

Best things you can do is use cruise as much as possible, and try to use the brakes as little as possible.

The mpg in the 3.8 trucks are an improvement over the 4.0 trucks, even if not by much. People constantly are reporting as good of, or better MPG than the previous generation with an engine that makes 50 more horsepower! These trucks will never be economy vehicles, but I've consistently gotten better mileage out of my '22 than my '07, by a couple of points. I live in the same place and drive the same roads. It's been a pretty good litmus test. As everyone eluded to, a plug in do-dad will not help you fuel mileage. If it was that easy Nissan would have done it already! The truck is tuned for a nice balance between performance, utility and economy.

If talking max mileage, that implies highway. I doubt power steering is much of a contributor in that scenario vs turn turn turn in town.

I don't think there is actual data for our combination and some hp draw estimates are based on old pump design

 

[shift_RUSH]

I'll contend that tracking one's fuel economy is worthwhile as it can provide some forewarning of needed repairs. When/IFF cats plug up is prolly close to the best example.

Cruise Control uses more gas. It is constantly on and off the throttle. It is better to hold a steady throttle position and let the speed vary slightly than to try and keep a constant speed.

The 9 speed transmission in Mercedes form came with two shift programs, one for performance and one for economy. It feels to me that Nissan chose a program closer to the performance one than the econo one. If I were manually shifting, I would shift sooner than the program does.

If Nissan could get a higher average they’d do it from the factory as a sales tool.

If your higher average means higher average fuel economy, then not true. Performance ALWAYS out sells fuel economy. The marketing departments use many tools to determine what makes vehicles sell more at a higher profit. Customers, even very car savy customers, will often forget about the high maintenance items like CV boots and timing belts when inside the dealership walls. From the design of the showroom to the training of the sales force, everything is programmed to divert your attention away from what they think could be a deal breaker.

It’s the corporate fleet average the company needs to make the government happy.
I had to pay a $1000 gas guzzler tax on my Challenger SRT when I bought it and the funny thing is I only drove it 50 miles in the last year and only 10,000 miles in over 10 years total. So it’s actually fuel efficient 😏

The cruise control gas consumption is subject to the terrain your drive. Surface streets in my area are flat and ideal for cruise control. Anyone in the Rockies or the Appalachian mountains roads might want to temper their foot rather than use cruise control if they're after better MPGs.

They lying!

Thats always a possibility, Seems odd most get about 20mpg, then one guy gets 30mpg,but maybe math isn't that persons strongpoint......

Probably because Nissan wanted the motor to hit the torque band. Shifting early is a torque killer. But I expect with light footed acceleration the 3.8 probably does not get near its full torque. Even the 4 liter shifts pretty quick. A little too quick at times. I think the first couple of years of the 5 speed had better mapping.

Believe me there is no Frontier from any year that gets close to that number. Iv'e had several.

 

[Striker65]

I've found the dash readout tends to be more generous with the MPGs, upwards of 10-20% higher than running the numbers yourself.
Mine has given me readouts of 29+MPGs, but running the numbers has gotten me 24 MPGs at best.

 

[kr2spilot]

I'd be a happy camper even if my 2022 SV got anything close to 23/24. Currently with 5k on the odometer it's showing 20.9 average. My 2016 SV was around 18 avg.
