9 ltr / 100 kms ? REALY? What do you get?
Who has a 1600cc engine and gets the reccomended fuel consumption of 9 litres to 100kms ?
as stated in the Brochure
http://www.1302super.com/uk_p27.html
Im sure I get only like 13 L / 100kms, but i dont do much freeway driving, and i do accelerate hard, also aero dynamics of the car may be stuffed
being a chopped convertible, and I am unaware if it is even a 1600cc engine, may have had work done to it by previous owner, but i doubt as the max
I've ever been able to achieve was almost 130km/hr with foot to floor on open freeway ( Dont worry, not a regular thing, just out of interest one and
only time)
What Do you get? Litres per 100 kms plus not engine size
(tried to do a poll, didnt know how to do it)

my Gregory's manual says 25 MPg or about 11L / 100kms average
I get 12-13L / 100 in city driving and 8L/100 on the highway
I seem to get that with every motor I have ever had - 1600, 1776 and 1916. Single and dual carbs
That is in a 1975 1303L
Have you ever checked your speedo on one of those 5km markers on the highway
I have had up to 20% low - only just clicked over 4kms in the 5 km stretch

Ive never tried that, mines in Miles so i'd have to remember it and calculate it later haha, but i will try that next time i drive south and go past
the one i know of
Yes I have a Gregory's manual in the car too, and im sure it didnt have the fuel consumption being that low and actually closer to what I actually
achieve. According to my speedo I get roughly 170 miles off a tank (So roughly 270kms). But like you said my speedo could b way off, i definately
going to try that now. THANKS

In my 1500 swing-axle bug with a 1600 twin-port engine I used to get about 200-250 miles out of 30 litres which is getting close to 9 litres/100km. I
think I get similar out of my S-Bug, somewhere around the 10 litres/100km range and I don't drive it like a grandma. I'm hoping to put on twin
webers soon though so I'm sure that will throw the good fuel economy out the window!

If you're just going off the odometer then forget it, they weren't even accurate when the cars were new, they always read low especially 12 volt
speedos that have the plastic odometer drive cog.
I thought my mileage was terrible till I verified by GPS my speedo only turns 8.8kms for every 10kms driven.
When I had a bog stock 1600 it averaged 8.5L/100km which is alarmingly better than VWs claimed average of 9.4L/100km or 25mpg 
Even on the highway it used to get down to 7.5L/100
Even my 1776 with 40mm webers driven spritely didn't get worse than 13/100L.

I know what you mean about the speedo being out - mine is about 400m short in the 5km set out on the highway - it has been since the first time I
tried it about 15 years ago. I guess that means that in the last 600,000km, between that and broken speedo cables, I am about 50,000km short. I adjust
my consumption figures by this amount to correct them.
My 75L bug with a 1916 with twin Kads, and with roof racks and some gear in it gets between about 11L/100 and 16L/100, depending on: whether I run 95
or 98 (or occasionly 91): whether I am moseying along the highway at 100, pushing it up the freeway or a back highway at 110 (or more), Zapping along
a windy road through the mountains, or worst of all, nipping around town: or most importantly, how angry I get it with my right foot.
When I tow my trailer full of tools (about 700 or 800kgs) my consumption goes up to about 22L/100.
For example, on my way home last Friday night, I got 13.1L/100 on Vortex 98 on the fairly flat and open Newell Highway from Parkes to Coonabarabran,
but 16.4L/100 on Vortex 95 on the windy mountains of the New England and Oxley Highways from Tamworth to Port Macquarie, where I was pushing it as I
got closer to home. lol
I know it isn't very economical, but by hell it sure is fun.

I have never been game enough to check My Fuel consumption.
it seems to use a lot of 98...
although it seems to use a lot less that it used to on the highway
I'm sure I use to see the needle going DOWN>....
I know its a lot more than My Wife's Suzuki Swift... lol

When I get My distributor problem fixed I'll have to check it..
using the GPS... I never thought of that... lol

hmmm? when I did drive my notch it took 3.5 tanks from sydney to kyneton (890km?)
quick math = to 16L per 100km fuuu
ckkkk
engine was totaled anyway.
my crummy old VP does 6.5L per 100km on the highway and about 8-10 in the city depending on traffic.

Most of my stock volksies with extractor exhausta got between 28 and 40 mpg on the highway.
My supercharged car got 9 litres per run.

yeah if the engine is built right you can expect great mileage. Its a sure sign of efficiency.
all of Raby customer's typically get 35-45mpg. Just a good example of great engineering. As he would say "its all in the combo".
Dam right it is.

When going to valla a few years ago, I could actually see the needle slowly going down on the freeway (going flat out ).
I get roughly 13L per 100km on a 1500 beetle with stock 1600 TP.

Well tuned 1600 in stock-ish condition will still average well under the 10L/100 mark.
All my heavy superbugs have but that is when all stock and in tune.
A worn out carby and a 009 instead of the original vac advance distributor give 6 cylinder like economy.
the difference in my 71 sbiug going from 009 to stock SVDA was huge.
Even Dads 1600 trike has got 10L/100 consistantly for the last 14 years and it has a weber and is not something you drive easily

Agree with the earlier comment regarding accuracy of speedos. In my younger days as an instrument fitter I worked on many a speedo and never found
one that was accurate. Even setting them up in the instrument workshop there was no guarantee to accuracy in the vehicle. Keep in mind that the
difference in tyre diameter will effect what the speedo reads e.g. wear. So will tyre pressure. So IMO the only real way to get the distance I guess
is use a GPS these days. Then how do you measure the fuel consumed. I would be surprised that all pumps are calibrated to a fine tolerance of
accuracy though a rough estimate can be obtained.
As far as I can tell the new 1600 in my '63 SC gets less than 10l / 100km.

The other thing about measuring the fuel consumed, is whether you are filling the tank to the same point each time - do you just go 'till the pump
clicks off? - or untill you can see the fuel in the filler neck? - or is the ground at the pump where the car is parked level?
You really need to average out over a number of fills I reckon.

My fuel economy has improved dramatically since I changed the heads, carbs and exhaust late last year. Originally a 1916 built by a specialist, it had
low compression heads, twin kadrons and engel 100 cam. Bugger to start and economy ranged from 10l/100km to 15l/100km, driving like a granny. Heads
went at 19,000 kms and with $$$$ down the drain, I sought advice elsewhere.
Thanks to a few people on this site and more $$$$, I now have CNC ported heads, dual Dellortos, 4 into 1 extractors and a fatboy exhaust. Starts first
time, has heaps of power, potters around at 60km/h in top gear, hits 130km/h in 3rd...and has given me fuel consumption ranging from a best of 7.1
l/100km (highway) to a worst so far of 10.5 l/100km.
Moral of the story for me - normal compression, better breathing, more efficiency....equals more power, more fun, and respectable economy.

I get a similar thing in the VP. I accelerate hard the tank with go from 3/4 down to less than 1/4
same thing happens when I turn left.
Then when I turn right or brake the fuel goes way up. In this case 1/2 goes past the end of the full mark on the gauge.
After hard acceleration for some time the level drops then after a while returns back up as the swirl pot is emptied and take time to fill back up
(the level float is in this pot) This only happens if the tank is lower than the top of the swirl pot (around 1/4 tank)
Probably can tell I know my car intimately

Interesting read, since I built my 1641cc I have been getting around 320miles from 30L in my 67, not sure how accurate the speedo is but now daily
drive a mirage as I'm selling the beetle but the mirage isn't any better as I only go to and from work in them!

I'd be checking the accuracy of the odometer, normally they read low not high.
Thats 5.8L/100 or 48mpg(imp) /40mpg(US) which is modern turbo diesel figures not 40 year old VW.
The early 50s 25hp 1100s barely cracked 37mpg(imp)

Still good I think!

11.9L/100km with the stock 1600.
must do that run again soon to check again

I'll have to keep an eye on my fuel consumption, as i just started a job which gives me a daily travel distance of 156km. I've never worked out what
my 1600 gives me.
