Mine sucks too!!! Its like once it hits half a gallon it just sucks it up like it's gulping water. I usually get about 50-75 miles from half to E. My roads are city, back road, and hills. But I do believe 20mpg is ridiculous, even with everything I just said. I mean at least 24mpg, is that too much to ask. I have been driving at 2000 rpms or less and it's killing me right now. I wanna see how much of a difference it will make. Right now I got 130miles and it's just a little past 3/4 left. I normally get 150miles out of half a tank, so we will see. Ever since winter Ive been getting 20-22mpg. Summer is 24-26mpg.

Mine are all at 35psi. I don't have a tpms anymore, it was disabled.

maybe 87 burns too quick and and explotion is happening before the piston gets to the top. Next fill up reset the tripdometer and add 89 octane and see if that helps slow down the explotion timing to where the piston is on top.

How many miles do you get out of a full tank?

I get at least 360 miles per tank, but I'm not sure how much fuel I have left?
The low fuel light doesn't come on, so it probably still has 2 gallons.
I will know the answer on my next trip to the gas station. it let mine warm up for at least 10 minutes in the morning and I'm easy with it, drive the speed limit ect..

Ive been doing mid grade gas since day one, oil changes every 3-4 months cause I don't drive alot of miles, and when it's changed, it's changed with half synthetic oil. Air filter is good. Full tank is about anywhere between 225-290 miles and that's pushing it. Light is on.

What Oil grade do you use? I use 5/30 changed every 3,000 miles

And..do you get the RPMs close to red line every once in a while?

I never red line my car, the highest I go is 3,000RPM and that's to get on the highway and the fastest I go on the highway is 65MPH to 70MPH


Another question is, what's the highest fuel tank mileage you ever had? Anything over 300 miles?
did the MPG started dropping right away or slowly started dropping to 220 miles per tank?

The dealer changes the oil, so I don't know what kind of grade it is.

I have an AT, so what ever it goes up to is all on the trans. Maybe once every month it will go up to 5000 rpms. But it's normally between 1500-3000 rpms.

The highest miles on a tank ive seen was 312 in the spring, and that was pushing it. It was always up and down in mileage since day one.

I use 89 on the versa also but it gets 360 miles.

You might want to change to 87 octane then
I had a Subaru Legacy L none turbo and 87 gave me 275 miles [it had smaller fuel tank] and when I put 89 just to see, 220 something. it was a 97 with 240,000 miles on

but if you do down grade to 87 and still can't get more than 300 miles,
then the fuel type is not the issue.
did you install a cold air intake or anything?

Its all stock except audio. Ill have to try that next. ive got about a lil over half a tank, and im at 140 miles.

 

[Versa S 2009]

is 140 city miles or both highway and city?
do you use a full tank per week. I know I do, that's why I have 76K miles on and I do a lot of high way driving. at least 20 miles one way
I also have a 6spd.
do you drive with the AC on?

That was 130 city, and 10 highway. Ive got about 180 miles now, and it just crept under half a tank that quick. It was city again. I fill up about every 2wks. I have AT trans, and I hardly use the AC. Right now it's heat, and summer is normally windows down.
