How big is the gas tank on your 914?, And how big does Porsche-Audi say it is? Options

[Gustl]

I doubt that there's a calculation error - in my opinion there's just an other way of measurement
as Jeff mentioned, the "key" should be the difference in definition of US norm and DIN

nowdays the DIN lays down the exactly way the car has to go for the measurement (x% city, y% standard road, z% autobahn)
in the 70s and 80s I remember that all german car magazines showed different consumption numbers:
x liter/100 km at 50 km/h
y liter/100 km at 90 km/h
z liter/100 km at 130 km/h
and the so called DIN consumption was a calculated mix-up of all 3 of them

so, if american standards were different, it's logical that they show a different mpg rate

btw - with the metric system our cars have a 60 liter gas tank

Is there a point to this?

Does it matter? I always considered my tank to be about 16 gal. so if you say it is 16.4, then so be it. The MOST gas I could ever fit in mine is 16 gal. (and that is after pushing down on the driver side fender to "burp" the air out of the tank)

The best milage that I ever got was with my silver street car back when it was a 1.8. I could go 475 miles before I got scared and would fill it back up. (the light was on) That would back up the claim of 29 mpg (U.S. measurement) also assuming that the odometer was correct.

When I put my stock 2.0 with fuel injection in my car, it seems that I can only get about 400 miles to the same tank full of gas or approximately 25 mpg.

What kind of fuel economy SHOULD I expect with a stock 2.0 (Euro P/C)?

I think the tank is supposed to be 62 liters, reserve included. Sixty is a nice round number as Gustl says.

Going over the various ads, the mgp figures vary from 23 to 26 and 29 with most of them refering to the 2.0 motor. This may reflect different model years, but I am not sure if there are enough differences in the car and engine to account for the numbers. We are not talking of 1975 and up models in these ads either. Canada should be getting bigger mpg numbers due to the larger gallon. I am not sure of the origin of the difference in the gallon measure, but I'd guess it was from the 1700's and may have had to do with taxes on alcoholic beverages. I also recall something about spirits being measured in fifth's, and it is a fifth that the American gallon is short.

The point of the whole discussion is the figures used in the ads. 29mpg in the US and 26 in Canada would be incorrect. A proper conversion wound be 29 to 36 mpg. That is far more reasonable.

The Haynes manual indicates 13.65 Imperial gallons, 16.4 US gallons, and 62 liters.
