What is the best way to improve my city MPG. What is the best fuel system cleaner. And what is the best PSI to run my tires at. (I have the stock SE 17" Rims) Right now I have the tires all at 40 PSI because at 32 PSI they felt to soft and mushy

 

you will damage your tires if you drive with lower/higher psi than recommended.

 

The best way to improve MPG is to accelerate slow and drive slow this is why I will never have good gas mileage.

 

HAHAHA, I think that goes for a huge majority of the org members...

 

Get some bg44k injector/valve cleaner at your local GM dealer ~$20. Don't go to Nissan as they bundle it with an oil additive for ~$30. Make sure your tires are at max recommended psi. DONT MASH THE GAS PEDAL - I keep telling myself this one over and over again, but somehow I can't seem to stop...

I've had mine on for about 5 days (unfortunately it took over a month to receive from the time I ordered it).

Very easy to install. Sounds good.

Best of all my mileage has improved. On the x-way I had always averaged about 25.7-26.3 mpg. This week (1000 miles plus) I was getting between 27.2 and 28 mpg (same brand of gas, same area travelled).

Thanks Berk!

 

I run about 38 psi no problems here

 

DON't MASH the gas.. i recently haven't been flooring it as much, and i'm getting 280-290 on my tank.. usually i get 240 because i would always floor the car =)
