Hi All,
I'm new so maybe you can suggest a better category for me to post this question in. I purchased a used frontier nismo six cylinder in December and am very surprised at the mileage. I'm very very lucky to get a maximum of 18mpg & that's ONLY when on a long stretch of flat land at sixtey-five mph. Should I just accept this or are there things I can do to improve this? I dislike American cars, but my American six-cylinder pickup had an average of twenty-three.

Thanks!

Aaron

Sure,

1. Switch to a high quality synthetic oil in the engine and rear diff. I use Mobil 1 fluids, 5W-30 EP in the engine and 75W-90 in the rear diff.

2. Use hi-way tires, not gnarly off-road tires. Keep them inflated to 38-40 psi.

3. Take all of the unneccesary weight out of the truck.

4. Use cruise control and set it no higher than 65.

5. Experiment with different octane gasolines using several tank fulls of each and record the mileage on the hiway.

6. Around town, drive like there is an egg under the gas pedal. Anticipate stops and roll up to them.

I can get as high as 23.5 highway on my 2007 Crew Cab auto 4WD V-6.

dannyg here.. The above of what boomer said true. Make sure your air filter is a clean one. I found out with these air filters if you see a 1/2 strip dirty change it that was worth about 3/4-1 mpg. I want on a trip to Jaxsonville FL bout 120 or so miles up there with the A/C on and cruise set at 70 for most of the way I got just under 22mpg on the hiway. Now heres is the funny thing on the way back home with the window down doing 65 cruise on I got only 19mpg. The A/C was on 2 on the trip up to Jaxsonville. Also I`m running 265/75/16s instead of stock 265/70/16s only bout an inch differ. 89 octane seems best for me. I do use a synthic oil in the engine next is to fill my C200 with some good synthic gear lube. Your nismo sould have a M226 rear in it check your axle code A CA is a C200 nissan built rear CC is a M226 a dana/nissan deal. My SE is a 4X2

Many thanks (although I'm not sure what "resistants" is) to all of you. I guess my point was that I was very very disappointed at the poor mileage my new-to-me Nissan got, especially since Nissans & Toyotas had a record for exceeding mileage of similar American vehicles. I was kinda hoping there was something mechanical that was causing the bad mileage. Instead, it was just bad design. I will follow all of the advice though! :)

Some folks say that aerodynamic drag increases by the square of the speed. So I always start off kindda slow then taper off from there!...

Have a good one while you can still laugh about it.. Don S..

Friends get ready for this…

In the future individuals will have to buy carbon credits. These carbon credits will be in the Commodities Futures Market and speculators will be driving the price up to $4.00 per credit!!!

I have a 2008 crew cab long wheel base Frontier 4X4, AT. I have never gotten less than 18 MPG. I never go over 70, do slow accelerations from start, use standard 5W30 engine oil, and have the stock fluids in the differentials. I have gotten as high as 22 MPG, I have no complaints. My stock BFG long trails have 35PSI. Just rolled 8000 miles, I hear the MPG gets better after getting near 20K miles

I was only able to test it a couple time since that was gmc a company truck. it got a 18mpg for mix of hiway and town loaded was about 12-14 mpg. Heres a funny story one day one of the sales people had the gmc an order of 13 Sq of shingles came in me and another guy did the drop in our trucks his was an 06 bowtie long bed 4.8 motor. My 06 se 4.0 found out that the long bed bowtie could only hold 4 Sq of shingles any more and the dang bowties rear would hit the tires. My little se fronty hauled the other 7 Sq of shingles and 4 buckets of tar. What the story is ment for is this are trucks are in a mid size class with 1/2 full size balls behind it. when you said 23mpg was that pre E10 BS fuel cause I do no I lost 2MPGs when that crap came out You can go look at any fullsize ride V6 truck and they come up short in a couple ares fit and finsh was mine. BTW the story is true and was not a bash on GM soon to be CM
