Thinking about gas mileage, Who has 17"+ or 20-26 MPG Options

[Jeremy1210]

I just bought a 97 ST that has 17" with 215/45. The gas mileage is pretty crappy with this car. I just took it to get the fuel injectors cleaned. But anyway, I remember reading posts of people saying there were getting like 20-23 mpg. FOr those people, what size tires are you running? On my 94 St i Have 16's and Im gett 30-31 mpg. I don't think 17'' should drop the mileage that much..

Anyway, if you have MPG in the lower 20's canyou let me know what size tire you are running? I'm trying to do some research on how much these 17's are going to cost me in the long run, and if there is something to do about it.

Thanks
Jeremy

ummm gallons are gallons regarless dude i don't know what you are thinking
now if your CONVERTING it would be UK=liters to US = gallons
UK gallons and US gallons are the SAME hence they are called a GALLON

if it was UK gallon to US gallon its not a conversion

Almost totally wrong in every respect I'm afraid.

Just because things have the same name doesn't mean they're the same thing. Last time I checked there were lots of currencies called a 'dollar'. They're not worth the same.

A world of information at your fingertips, and you still couldn't be bothered to look it up.

From Wikipedia, the free encyclopedia.

The gallon is a unit of volume used for measuring liquids (as well as dry matter).

* In the US a fluid gallon is exactly 3.785 411 784 litres: see U.S. customary units
* An Imperial gallon is exactly 4.546 09 litres: see Imperial unit.

At one time, the volume of a gallon depended on what you were measuring, and where you were measuring it. But, by the 19th century, two definitions were in common use. The wine gallon, or "Queen Anne's gallon", which was 231 cubic inches (and became the legal basis for the U.S. fluid gallon), and the ale gallon, of 282 cubic inches.

In 1824, Britain adopted a close approximation to the ale gallon known as the Imperial gallon. The Imperial gallon was based on the volume of 10 pounds of distilled water weighed in air with brass weights with the barometer standing at 30 inches and at a temperature of 62 degrees Fahrenheit. In 1963, this definition was refined as the space occupied by 10 pounds of distilled water of density 0.998 859 g/mL weighed in air of density 0.001 217 g/mL against weights of density 8.136 g/mL. This works out at approximately 277.419 45 cubic inches. The metric definition of exactly 4.546 09 L was adopted shortly afterward.

The United States, by this time, had already standardised on the old wine gallon. It was at one time defined as the volume of a cylinder 6 inches long and 7 inches in diameter, or 230.907 cubic inches. It had been redefined during the reign of Queen Anne as 231 in³ exactly, which remains the U.S. definition today. Thus 10 U.S. gallons equals approximately 8.327 Imperial gallons. The Imperial gallon is about a fifth larger than the U.S. gallon.

Both the Imperial and United States gallon are divided into 8 pints. However in the US a pint is 16 fluid ounces whereas an Imperial pint is 20 fluid ounces. Thus a U.S. gallon is 128 fl oz and an Imperial gallon is 160 fl oz; this means that a US fluid ounce is around 1.8047 in³ and an Imperial fl oz is around 1.7339 in³. The US fluid ounce is actually bigger than the imperial, although the US gallon is smaller.
