414 after this week's fuel up with avg 25 mpg and nothing but 91+ touches my car, why would anyone put anything less is beyond me..

 

296 always fill up Sunoco 93 and i have an 08 gs350 awd...taking local roads to work sucks...getting an avg of 16.9 to the gallon

 

Yeah... Depends mostly on driving habits. Generally I think highest range at identical habits will go from GS300 RWD > GS350 RWD > GS300 AWD > GS350AWD > GS430 > GS460

 

We typically see 380 at fillup. Have (once) had it up to 420 on a road trip. Never fill with anything less than 91 octane.

 

same here. if you talk about premium gas from different brand stations then i can see the debate, but why would anyone put regular or medium instead of premium in our cars, i can never understand that. even when gas was 5 bucks, only premium for my cars

 

I can get about 410 miles per fill-up from a premium no-name gas station but only around 395 from a premium Chevron brand. Could it be that the additional additives that Chevron uses actually contains less actual gasoline?

 

mine says around 380. a few things i learned to help save gas was to try and keep revs under 2000rpm and simply to leave earlier to give myself plenty of time to get to my destination. by giving yourself extra time you drive more leisurely and aren't in a rush to pass people or speed.

 

Mine only get between 320~350, always fill-up with 93 octane!?!

 

no, chevron's additives is for engine cleaning, makes your engine last longer.

 

Is it normal for a 2007 GS350 AWD to give out about 240 miles? I use nothing but Petro-Canada 91 or Sunoco 93 and work about 10 miles out, lots on city driving. I find it eating more gas then my 98 GS400. Do I have a problem???

 

2006 - GS430 ... getting 335 - 350

 

if you do a lot of city driving for sure gas mileage, so range showing 240 might be possible (though still on the low side imho)

 

yea seriously.. i wonder how some people's mpg is so low..

probably...
1) lead foot
2) always run A/C
3) PWR mode always on
4) city driving
5) awd
6) extreme climate
7) winter gas
8) low tire pressure
9) crap gas

 

Wow . I feel bad I get 203 but I do live in brooklyn where there is alot of stop and go , a light at the end if every block .

 

I would say mostly city driving but with my V8 GS400 I got about 290-310 City. The worst I got from my from my GS400 was 220 range and that was due to Oxygen Sensors. I have a feeling something just not right and will take it into dealership.
