Has anyone ever setup a VW Bug for High Mileage? I have a 68 Bug..wanna set it up for HIGHER Mileage any setups or carbs available anywhere?
Thanks Paul

This applies to most neglected VW beetle engines out there (most of them are).

Nope, never heard. Google might know something.
In general, an engine needs to be fed a certain amount of gasoline and air mixture for it to operate properly. If everything is in good shape, it is very difficult to reduce consumption without risking something.. first thing that comes to mind is eliminating the auto choke, and jetting the carb lean. Missing choke causes accelerated wear and if you pump the gas pedal when the engine is cold to keep it running, you win nothing. Running the engine lean will eventually cause engine breakdown, as well as poor performance from the beginning. (You end up pushing the pedal in deeper, especially to compensate for the take-off "bog", and thus you both make the ill effects worse, AND use more fuel too.. so no savings there)
The VW aircooled engine just isn't a particularly economical engine to drive. It's old technology, and for a car that size & weight, the fuel consumption is horrible compared to today's technology.
But low fuel consumption is NOT why you would buy an old beetle anyway, is it? If that's what you are after, buy a diesel Lupo.
The hands down winner in the list of tricks to reduce fuel consumption is the easiest too. Keep your foot out of it.

From memories of Mobile runs the routine goes like this 1.Raise tire pressures(45# sounds right) 2.Smaller jets in carb.3.Remove excess from trunk(tools,bodies,ect.)4.Stronger spring on throttle linkage.5.Light weight oil in crankcase .There are a lot more silly things that they would do also but that should get you enough trouble for now.Even the best ACVW is a gas guzzler by todays standards.Domestic Pick-em-ups get better mileage care of EFI and computers.Frankly, the way you drive has more to do with mileage than anything.

cant remember which way round it works but US gallon and UK Gallon are different ammounts so dont know how good 46mpg is !
The above link shows and article on high mgp attempt.

The change is quite significant... 46 miles per imperial gallon converts to 38.3 miles per US gallon.
There are only 0.833 imperial gallons in a US gallon. Canada uses the imperial gallon.
Not sure of the history behind this... I'd have to Google it... but the solution is rather obvious... METRIC SYSTEM!

I can never remember which is the metric one - US or UK? I always prefer to use litres to avoid confusion :-)

Nothing is going to make it last longer or get better milage then as stocker as Jan said. If you try to get better milage you may run too lean and that will kill engine life. If you make the engine more powerful you start to lose engine life and may eat more gas. Another reason I went T-4 in my bug. THe engine was made for a 2 ton bus, so it not going to work hard in a bug. You can expect well over 150k miles no problem in a 1700 lb car. Also the extra power in the light car you give you the same milage as a stock 1600 T-1. Yet you will have twice the hp as the 1600 if you are runing a 2.0 with dual carbs. Mild cam will surely give you double hp and a very nice high speed driver.By the way the 2.0 is a stock engine.

...............A stock engine with the original carburetor is about the best available option for gas economy in a pre-75 year model bug. Driving style is far more important. You're not going to match the 38 mpg at 65 mph of a Honda civic with an aircooled engine that was designed 70 years ago unless you drive it at a much lower speed. Even then, you'll have trouble getting 30 mpg unless everything is perfect.
...........With my '77 bug, the L-Jetronic EFI with a stock cam & exhaust system on a fully balanced Berg 1679 gets about 28 or 29 mpg at a steady 65 mph. Unfortunately, I like to drive at 75 to 85 mph...........lol

LOL OTOH I had a KG w/1600cc (stock) that would routinely get 38-40 MPG at a very steady 60MPH. (I did cheat a bit with more advance than is recommended but one has to assume the risks that go with it...)

..............Foul!
......That KG was more aerodynamic than a bug and I bet you even kept the windows rolled up to lower the drag coefficient and maybe you even put 40 psi in the tires too..........lol
.......I'm running 38 deg total advance with 87 octane gas but that's because I've got semi-hemi heads.

My 1961 stock 1200 28 PICT setup gets about 38 MPG... so the older 40 HP and earlier motors weren't bad at all... That's 38 miles per IMPERIAL gallon by the way... I guess if you meant miles per US gallon, then it's a bit lower at 32 MPG if I do the conversion.

................How fast do you drive, on average? I've heard more than once that the 1300 in '66 is the best running and most economical bug of them all. Right Howard?

With my stock 1300, I get about 31 miles per UK gallon... Bang on the original performance figures, in fact!
