I was getting around 300miles to a tank. Now for some reason im lucky to get 200. I have the 3400. What would cause this? MAF, throttle body, and air filter are clean. Just changed the fuel filter about 4 weeks ago. The car still runs fine just sucks up the fuel like crazy now. I can't see it leaking anywhere either. Any thoughts?

i get the same. what kind of mileage do you have on the engine?

spark plugs and wires can also be a cause, and how you drive is also a factor

I have 97000 on the motor. Spark plugs and wires got changed with the fuel filter. I don't have a lead foot either. I just filled up today so I will see how fast this tank goes.

Well, I drove my Alero about 750kms today. I used 43L to drive 527kms.

I must have just got some shitty gas because its not sucking it down like it did before.

I was getting that too until I changed my spark plugs and wires... It's doing better, but it's still kinda blah....
