2010 Rogue - Fuel Economy

Postby disallow » Sun Feb 09, 2020 5:55 pm

Hey everyone,

Just thought I'd throw this out there as I'm struggling with my car, recently the fuel economy has gotten to the 11-14L/100km or 16-21MPG. We've had the car for about 4 years now, and its always been right at 8-10L/100km before this. (24-28MPG). So a significant drop.

2010 Rogue SL AWD
230k kms on the clock. Owned since 105k kms.
No CELs. No stored codes.
Not running poorly, good performance, acceleration etc.
No funny noises.
Plugs changed last year about 20k km ago.
Air filter is new.
Ran seafoam for a few tanks. Idle has improved. Fuel economy same.
Pretty sure its not a winter gas thing, that usually only affects F/E by about 5-10% or less.

Had an issue last year with the Crank Position sensor, and the ECM power wire. Fixed that. But for a while it was running badly as the CKP sensor harness was shorted. Wonder if running it like this fouled the O2 sensor.

I have an Innova 3100j code reader that monitors the I/M management. It seemed a little hokey at first, but it has indicators for the major engine management systems like EGR, HTR (O2 Sensor Heater), CAT (catalytic converter status)etc. All of these go 'green' after about 10 minutes of highway driving at operating temperature, except for the O2S (O2 Sensors) and EVAP indicators.

Is it possible that my O2 Sensor(s) are getting lazy? Suggestions on what to do? I thought about just replacing the Upstream one, NGK replacement I found for $135 Canadian, which seems like a decent price.

The evap thing makes sense, I would imagine there is a bad actuator in there as when I fill up, the pump clicks off really early and I can usually squeeze at least another gallon and a half or so into the tank. So i don't think my poor fuel economy is based on a bad calculation either, as I do monitor my fuel input vs mileage driven.

Thanks

Do a search here on cleaning the throttle body and/or the MAF sensor. If you decide to clean the throttle body, I'd suggest removing it and not doing it on the vehicle.

Have you changed the transmission fluid? My 2011 Rogue gets poor gas mileage until it warms up in cold weather, the rpm is a little higher when cold and then goes down after about 10 minutes of driving. It doesn't get that cold here in the southeast US though. It may be worse with bad fluid and colder climates. I wouldn't go any more than 30,000 miles on CVT fluid.

I get 16-17 mpg in the city rock solid.

Must say the oem tires had great mileage.

I'm just happy the original cvt is still alive.

I have the least aerodynamic with heavy exterior accessories, so I am not surprised.

It will get worse when I add all terains after I add some spacer lifts from russia.

Forgot to say my all terrain with new wheels should be 6 pounds lighter altogether if the numbers are right from the info I get online.

Plan to get 225/75/16 on my 2009 rogue.

Thanks for all the replies!

I haven't had a chance to look at the Throttle Body yet, but there don't seem to be any other symptoms pointing at this being the culprit, idle is great, no issues with acceleration or performance. But the exhaust sure smells rich. I am still wondering about my Fuel Air Ratio Sensor (Primary Heated O2 Sensor). Also, no codes. But I will definitely take a look!

Also, I have not changed my CVT fluid for about 60k miles. I checked the fluid and actually had it tested at one point about 10k miles ago at Blackstone, and they indicated it was still good. However, this is definitely on my list, have to buy the fluid. Definitely NOT buying it up here in Winnipeg, as the dealer literally charges $42/qt (canadian currency, so same as $31 USD). Highway robbery. I will be going with the AISIN ATFNS2 for $8.81/qt Canadian, same as the stuff Nissan sells. I will buy it from Rockauto and have it sent to a border parcel service, and pick up when I'm in the area.

But that being said, I don't think the CVT fluid is the culprit here either, transmission does not seem to be having any issues.

Speaking of CVTs, I almost bought a salvage 2010 from the local insurance auction a couple months ago. $400 plus a tow, only had 115k km on it (70k miles). Engine, Trans, rear diff, driveshaft, and all the other good parts on it. But couldn't convince the wife we needed a derelict vehicle in our yard, and it seems that ours, although high mileage, is in pretty good shape. I may not need a transmission. Hope not! Though if the time comes, it does look like I can get one from the local LKQ for about $700 with a 90 day warranty.

and I don't think this 2.5L engine will ever have an issue. Just saw this video of a 2007 Frontier, over a million miles with the 2.5L engine in it. This powerplant is so rock solid. Love it!

I'm using Valvoline CVT fluid at the moment, $8 a bottle from Walmart, I drained and filled on January 1st and did it a second time two weeks later. The transmission was whining, the fluid change fixed that. I'll drain and fill every 30,000-40,000 miles. The service manual says change every 60,000 miles or have it checked and to change it at 210,000 miles no matter what.

I bought an air filter from a local auto parts store and threw a lean code, not right a way. The rubber around the filter wasn't as thick as the Fram I replaced it with. I cleaned the mass air sensor and O2 sensor and changed to the Fram air filter and the code never came back after I cleared it.

I drive with O/D off quite a bit, less gas mileage but it's more fun. Occasionally I'll keep it in L on twistie back roads.
