|Hey guys what's going on? I drive a 2010
nissan frontier Pro4x v6 with 78k on it.
My gas mileage has fallen really low
lately (around 11 mpg) and I don't know
what to do. I take care of my truck and
there is no check engine light. My buddy
thinks it's sparkplugs so I'm doing that
this weekend. Any help would be great.
Lot's of thing's can affect MPG:
Type of Tire's, Some Tire's hurt the MPG. Low Tire Air Pressure. Dirty Air Filter. Heavy use of Gas Pedal, & Brake Pedal. Oxygen Sensor like previous posting. Modification's that affect Aerodynamic Airflow. 4wd's don't get as good MPG's, as 2wd's usually.
If your engine is useing too much Oil,, the Cat's can get restricted,, and that will cause less MPG's.
For the most part,, I've found that keeping the Truck & Engine as Close to stock as possible, as well as keeping up with the Maintenance Schedule,, is about the most that an owner can do for optimum MPG's,, and Vice Versa,, the more Mod's that are done,, the worse the MPG's usually get.
Has the Maintenance Schedule been kept up to snuff?
On my '13 SVV6, I'm getting right @ about 20.5 MPG in Mixed Driveing, Maintenance is up to snuff, easy on Gas & Brake Pedal, Shell Regular.
Good Luck,, and let us know if you find the problem.
