I would take it somewhere else for a second opinion.
They only way I can see you getting that mileage is if you drove it around town, no highways, and was using the gas pedal like an On/Off switch lol

Yeah, when I had my IS350 AWD, I was averaging about 18-21 mpg (13-11 l/100km) and getting around 310 miles (500 km) per tank.
In my GS350 AWD, I get about 15-18 mpg (15-13 l/100km) and about 280 miles (450 km) per tank.

Man that’s really low, I took this desicion based on some comments regarding the 250 AWD compared to the 350 AWD, I mean gas wise, much of them were saying that mileage was pretty close, but now I’m just realizing that is much worse.
Well I guess I have to swallow the bullet now.
Thanks
but the problem is some other member's car has better mileage then mine too... I'm sitting at about 15-16L/100KM and other members here with the exact model sitting at 12.5-13 ....

A few things you can do
1) Check tire pressure
2) Change/Inspect spark plugs
3) Run out the tank and fill it up withh premium fuel like many suggested.

Should I increase PSIs?

See some pix of my IS350 FSport all covered up in Los Angeles, jealous of all the other cars getting lotsa exercise, while I'm working out east. Suspect I might drive it only 5 months per year so maybe I should sell it. ANY TAKERS?? Some friends recommend pouring a gas additive in the tank before ever starting up again!!
PS >>> mind telling us your OTD price $$$ and the interior color?

I believe you’re right I did that with the first car but never to aggressive, I’m going to have to drive it a little more like if I stole it.

If there's any consolation @ Makool a lot of us are in the exact same boat IMPULSE BUYING. Lexus sales folks as laid back as they might seem are skilled at encouraging this.

I got the black interior, I had the Rioja Red before so I wanted to try it, kind of regretting it too. I was able to get the car for 53K CAD all in after discounts, trade in and promotion. My monthly Payment went up only 60$, and my insurance only 8$.

PS >>> with Vancouver's lack of freeways & highways unfortunately the best gas mileage might achieve is 20 mpg = 9 kpl but that's still better than LA street driving.

If your car is Brand New then actually that is EXTREMELY GOOD = 41k USD coz in the USA that car brand new would be around ~50k USD OTD = 64k CDN. Are taxes included in the 53k?

I have the AWD version and i have a ratio of 50/50 on highway vs street and i get a very constant 14.8 l/100 km and full tank only gets me like 400 km. Yup, you will be in shock lol.

Remember is 36 psi cold start...that's the recommendation. Honestly i don't think the psi play a part. I have my psi all over the place and my mileage is still same old ****. It only got better when i had my F sport intake but then i have remove it and have another after market intake and now my mileage is back to the normal 15L/100 km.

Gas Mileage Royally SUX
Yep - fully agree - unless you live somewhere with zero stop signs & traffic lights, or doing clear highway rolling, and ALWAYS in Eco Mode to boot, I will never, ever, believe getting better than 24 mpg on an IS 350 FSport.
