The superbug tank is 42 litres - 11.2 US gals.
The standard bug tank is 40 litres - 10.6 US gals.
25mpg (US) is about right for a stock 1600 superbug - 280-290 miles per tank full.

| Litchfield and back, 220 miles, 25 mpg. But don't let the needle get too close to the "R" zone on the gauge. When I go around a sharp curve at speed I suffer from fuel starvation and it takes a few seconds for the fuel to flow again. |

| I am running a stock 74 SB, and I have seen up to 30 MPG on long all-freeway trips. |

Matthew,
30mpg (US gals) is very good for a 74 superbug - you must have it tuned well. You can get this economy easily enough with the 1970 or earlier bugs with the smaller 30 series carb and lighter body, but 30+ is very good for a superbug.
79 Supervert,
You should be able to get every last drop of of the VW tank, so I wonder if the guage is in fact over-reading a little (saying you have a little left when it's virtually dry) or the pick-up is not quite at the bottom of the tank (the later superbugs have a side-entry pick up which bends down to the tank floor). In any case, the fuel bowl contains a small cup full of fuel, which should run the car for about 1/2 mile before it sputters. I often drive my car (68 standard) until the needle is touching the left (really empty) end of the R zone, and find I still have about 2 litres in the tank when I fill it up.

| I don't have a fuel bowl if you are referring to a carb component as I have FI. If instead you are referring to a fuel bowl in the gas tank then I don't know: maybe I have a replacement fuel tank as it looks awfully new for a 24 year old car and perhaps it doesn't have the bowl. When I fill the tank the fuel reaches almost to the filler cap but the gauge is just shy of the last line. So it seems the gauge is inaccurate at both ends. To be safe I have to fill up when it drops below the 1/4 mark. |

Thanks for the info guys. My bug was getting 18mpg. But the timing was too retarded. Could this be the cause of poor mpg?? Now I think the mpg will be on par with the timing set correctly.
thanks. |

Thanks Rob,
It is a new engine(only about 1,000 on it), and I am striving to drive it in a mellow fashion. I am also allowing lots of warm-up time, watching the tire pressure. It has 185/65 \r15's on it, which I am sure increases he rolling resistance, They are what it came with from the P.O., but I like having rubber on the ground.
I will eventually add a Fuel Economy section to my web site, and start publishing a graph or something...

79 Supervert - I was referring to the carby fuel bowl, so you are right - that doesn't apply to the FI cars (but it DOES to the stock 74 mentioned in the original post - FI started in 75).
It does sound like you have an inaccurate sender or guage, which seems unusual -They are usually VERY accurate.
