city driving and 20% hwy ?? good sparkplugs tune i did have a CEL p1149

Depends on how slow your city driving actually is, but given the GS300/400/430 all get about the same MPG, and my GS430 under similar situations with 20" rims gets me about 18 MPG I would say about that much. If I do about 50/50 I get around 19/20 MPG.

 

I'm getting around 22-23 mpg

 

I hope that's like 90% highway..

 

I have a 04 gs300 and i do mostly city driving, probably close to seventy-five percent, but I get about 20mpg.

 

I'm not sure if there a big matter by changing rims to 20s.
The MPG is really depend on how you drive. as i experienced your gas tank will drain fast if you accelerate fast with a high RPM over 3k. that's why i always did slow accelerate to 2.5k RPM and let it slowly shift.
HIGHER RPM will SUCK ur Gas.
Heavy ******T will wasted your gas.
heheeh...
i drive 65-70 is about 2.3k- 2.7k RPM. go 80 MPH, the RPM will be 3k something..... in addition, your car has to be in a normal condition.
Correct me if im wrong.
GL

 

I get 20 city just cruisin .. Which aint the greatest but isnt too bad either

 

People get mad when I take my time to accelerate

 

As long as it saves you gas, who cares, lol.

 

True that True that

 

LOL gs's are so sluggish from a stop and if you do press the gas you feel like your killing the car, sometimes it takes me 5 min to get to 50 mph

 

21 Average here...normal mixture of city/highway driving...not being lead-footed also

 

LOL. or you can say my lady is fast walking on the street. hehehhee.
when the red light turns green, my lady will crawl, then walk and finally run....... ehehhe she is showing her sexy body and sexy movements to everyone on the street.

 

60hwy/40 city, I probably get about 20-21...but I'm not on 20s, not sure if that makes a big difference in mpg or not.

 

Same thing here. People are in such of a damn rush nowadays.
