I own a 2011 Nissan Versa Hatchback with just over 83k on the odometer. Apart from scheduled maintenance, regular oil changes, and tire changes/rotations I have not done anything to the vehicle. Living in Southern California a couple months back I started noticing a marked decrease in fuel mileage. Generally I can get +/-305 miles on a 10 gallon fill up if I stretch it to the empty line. Suddenly one tank only made it to 285 miles before hitting the empty line. Then it went down a slight bit more. Nothing else seemed to be going wrong with the vehicle. No Check Engine Light, or other Warning Lights for that matter, no loss in power (the car isn’t powerful any way), idle feels fine and so does the throttle response/engine revs when I drive.
I brought it in for a Diagnostics test to be done for $120. I’ve attached the link to their report so that you guys can check it out. Basically they want me to do their Fuel/Air Induction Service for $300, then replace the Spark Plugs, the Mass Airflow Sensor, and the Air filter. I’m going to have a second opinion made but I also wanted to bring this up to the group here. I’ve heard before that this Fuel/Air Induction Service can be a waste but I think in my case it potentially might not be a waste. If it gets suggested by another mechanic then I’d probably consider it.
All in all I was looking at $1200 out the door but that also included an oil change, headlight replacement, and replacement of an engine mount that had failed (I guess) causing excessive engine shake. If I just had those Fuel/Air services done and parts replaced I was probably looking at close to $1000 out the door.
This link is to their Diagnostics report for my vehicle. It’s somewhat in depth and hopefully to someone who is more fluent in mechanic language it can tell a lot more than it did to me. Thanks for any and all input. I am currently in the process of getting a second Diagnostics done from another shop this coming Saturday. When they have a report I will come back here and share.
