I usually drive 5-10 miles a day, mostly city traffic (stop, go, stop, go) and I average around 13 miles a gallon. Is this considered low? I have a few things that are gonna be changed that will hopefully make a difference (valve cover gaskets, clean MAF sensor, clean throttle body, and installing new temp sensor). Reading other posts, people usually get 16+ city MPG, just thought mine was extremely low. I usually drive like a grandpa, and I let her go once in a while. Let me know what you guys think.

 

That sounds about right with pure stop and go.

 

I bet your car barely has a chance to warm up before your trip is over. Before a car is warmed up it's running very rich, then toss in the stop-n-go and it's a MPG disaster. That kind of driving is great for a hybrid or electric and not so much for an 8cyl big sedan if you want MPG.

 

totally agree with campsi , I drove my LS430 2005 in a lot of city and im easy on the take offs , im running BP or Shell Premium 93 octane and I average about 16-17MPH Highway about 24-25

 

13 is exactly right with that driving. Thats all I got when i did that short commuting

 

MPG on my car has always been stellar. Average mileage per the car's mpg display is 21.4 - not re-set in years. Recent 1200 mile road trip back and forth on I-10 produced 27 mpg tank averages at 70mph average using 91 octane. In city driving with 30mph speed limits everywhere, we get 17-18 mpg.
