I grew up with Nissan... Especially the Max. I currently have a 4th Gen. that i am constantly filling up. My fuel economy is bad and i need suggestions. Help!!!

 

Is your check engine light on? Is the check engine light working. You decided not to tell us the mileage or your fuel mileage. Maybe general maintenance/tuneup may be called for. Replace the air and fuel filter, clean the throttle body and see what happens.

 

+1 on general maintenance. Spark plugs, etc.

 

Gas filter, PVC valve,

 

first off, use 91 octane if you're not already. then general maintenance. maybe some Lucas or Techron fuel injector cleaner, I noticed that helped me. and clean your throttle body, adjust throttle cables.
