Nissan Rogue Forum

Morning!
Just curious - is everyone using regular gas, or are you using premium? Wondering if a difference would increase my mpg.
Currently I'm getting 25.5 mpg in a 2011 rogue and wondering how I can improve that.

Thanks!

25.5 is pretty darn good in my book. Are you getting that off the computer or have you calculated it by hand? Don't beleive the computer until you check it by hand first. My 08's is a couple tenths high, but my 02 Altima was consistently almost 2mpg high. 02 Audi was dead on accurate.

I use regular gas and get around 23 city/25 highway.

You won't get any benefit out of using premium fuel, you'll just spend more money. The 2.5 is designed to run on regular gas, the higher octane in premium is there only to help prevent spark knock in cars that are tuned with more advanced timing to try and squeak a bit more out of the engine.

Best impact on gas mileage is to drive conservatively, keep your car clean, tires properly inflated and the car running and maintained properly. Take out stuff you don't need in there as additional mass equals lower fuel economy...the Rogue is very light already though.

No need to use any gas but regular unleaded. I get 26-28 mpg. I try to feather foot the gas and keep the revs down. I try to keep speed reasonable, which I do since I won't speed. My commute is 60-70 mph for 18 miles. Around town mileage drops quickly. Also at higher speeds obviously. I think the car would do well at 50mph constantly, but that's not likely.

I use syn oil which may help mileage. Or not.....

agreed!
Oddly enough i get 23mpg's on average on highway & about 27+ rural.

close enough
-actually if an engine runs a high compression ratio, and you use regular gas (which has less octane) the regular fuel could be compressed and over heated by the compression cycle causing slight pre-detonation- aka knock. Knock occurs when the peak of the combustion process no longer occurs at the optimum moment by the spark-plug at top-dead-center.
(basically its exactly how a diesel engine works. it compresses the fuel until it explodes on its own.)

engines now a days have knock sensors to adjust the timing the fuel enters the cylinder, to prevent the pre-detonation.

(thats all octane does = allows the fuel to be compressed more without early detonation)

I'm using regular, and have tracked every fuel up on Fuelly | Share and Compare Your MPG.

Driven 13,375 miles, 531 gallons consumed. Avg MPG 25.2 -- Last MPG 24.6 -- Best MPG 29.5 -- Estimated City MPG 22 -- Estimated Hwy MPG 26

Milage suffers during winter with the 10% ethanol added in, plus ideling to warm up.

my dad said a couple days ago, supposedly they wont be using ethanol anymore.
any truth to this?

im a news nut- but i didnt hear anything about that.

Sorry, no idea about ETHANOL no longer being used. Wishful thinking perhaps?

I think ethanol serves only to absorb moisture. And it's a boondoggle for the producers, raising the price of corn.....

Actually it was originally thought as a great fuel additive to reduces harmful tailpipe emissions, but then the hippies realized that creating the crap actually makes more pollution then it saves.

wait till the hippies finally wake up to hybrid cars, and how much pollution they create versus save!
