Why is my Gas Mileage So Great?
#16
I could see you maybe getting high 20s or up to 30 but not what you are claiming. And uhhh... E15 in your gas is actually going to make your mileage worse than ethanol-free gas would.

I mean **** that's better than what my stock B18 Civic Hatch gets. I can squeeze about 32mpg if I'm going 65-70ish. Usually it's 29 or so at 85-ish. This is a 2144lb car lol.

Thanks everyone for all the info. I was not aware that the rear end was different on the newer models... maybe that explains my mileage. At 85 mph, I'm turning around 2,300 rpm. I consistently get around 34-36 mpg at 80-85 mph, but I only get about 28 mpg at 60 mph.

Run a full tank all the way to empty and then calculate your mileage. I always felt that it wasn't as accurate when you "top off" like that.

This is the quote from the Lexus brochure on the SC's :
Its quite possible to calculate inaccurate numbers cuz topping off what you use, divide gallon into the miles driven can get a higher number when just "topping off". Its not totally accurate. Drive a whole tank, then fill up and divide by the gallons filled from empty is most accurate which is known as "Tank Avg".
I'm not saying OP is wrong, its possible to calculate those high numbers, one time i calculated 30.5 mpg "Topping off" in my GS400 going 85mph too but later on a 2nd tank did the "Tank Avg" and was getting 27.5mpg 95% hwy.
Its Possible to calculate incorrectly, but most uncertainly its not the actual MPG.. A 4.0 V8 going 85+ to get better MPG than a Camry 4cyl.. Most people would laugh in your face.
SC 400: Actual mileage will vary with options, driving conditions, driving
habits and vehicle's condition. Results reported to EPA indicate that the
majority of vehicles with these estimates will achieve between 15 and 21
mpg in the city and between 21 and 29 mpg on the highway.
