#39 of 306 2007 Nissan Altima Gas Mileage Problem
Jun 16, 2007 (5:21 pm)
I drive a 2005 with the 2.5L and get 29mpg with 25% city and 75% highway driving, 75 mph on the freeway. There is really no reason for your car to be pinging on 92 octane gas, I drive in the Mojave desert in the summer time with the air on without pinging and I pump 87 octane. What brand of gasoline do you use, is it a Tier One gas like Shell or do you use some no name gas or worst, Arco? Just a thought.

I have used/tried Mobil and Shell Gasoline with the same results. I would never put in a no name Gas. I can't understand why I am having this fuel problem.

When you took your car to the dealership did the service department checkout the car? Did they plug it into the computer and do a diagnostic engine check? Or did the salesman just blow you off? Pinging and bad gas mileage can be any number of things gone wrong under the hood, like a bad O2 sensor. Normally a engine problem would trigger the check engine light but, we all know how unreliable electronics can be at times. If they haven't checkout the car, I would take it in and have them do a complete engine diagnostic, it's under warranty. If they don't agree, take your complaint to Nissan USA and see if they will help. The squeaky wheel gets the oil.

I will have the car rechecked by another dealer. Thanks!

I have the same problem with my car. Did you find an answer to your problem with fuel mileage?

I have a 2007 Nissan Altima 2.5 SL with the same noise when the car is cold or sitting a while. I replaced the engine oil with Mobile 1 and also added in a bottle of Lucas oil and now the noise is very low when I cold start. I don't know why I have to use any additives to help to remove the noise when the engine is cold.
Maybe an engine recall coming? Please let me know.
