Who's got the best MPG and how?

[deronmoped]

Try a locking gas cap.

At close to $3.00 a gallon and how easy it is to fit a siphon hose down into a Buses gas tank, I would not rule out gas thieves.

Made a trip from seattle to ruby beach. Loaded with 6 people and lots of stuff, doing 55mph the whole way.

1969 1600cc Dual weber

I got 24mpg on the highway. But in the city....don't wanna talk about it

Here's a picture of my engine. I think I have a type 4 engine ?

I was happy to get an increase of 2mpg this year on the same trip that I take every year (380 miles round trip). Got a solid 22mpg this year. I have a stock setup in my 70 bus 1600 sp only mod is the electronic ignition. Prior to this trip I installed a new mech fuel pump, new cvs, rebuilt the carb, fuel filter, rebuilt gen. and then just regular maintenance. I was loaded for camping, 2 people, and pushed her pretty hard at an average of 65mph, no headwind going down. I run Prime Well PS850 tires- P185/75/r14 treadwear 460 traction a temp b.

I think were finding out why you don't get good mileage

crankyjellyfish,

You're going to have a hard time until you learn more about your vehicle yourself - rather than relying on others to explain some very basic fundamentals (i.e. what type of engine you have).

There is an abundance of information online about the VW Type 2 (that means bus, transporter, etc.). Type 2s were made with Type 4 engines from 72-79. They became fuel-injected in 75. The Type 4 engine is NOT inherently fuel ineffecient... as you can read, most of us get around 20 mpg -- that's pretty good considering the weight of a Type 2 (particularly those of us that have the extra weight of a camper conversion - over 3000 lbs) and that these engines produce less than 70 hp. Here's some more info/history (copied from wikipedia)...

In 1968, Volkswagen introduced a new vehicle, the Type 4. The model 411, and later the model 412, offered many new features to the Volkswagen lineup.

While the Type 4 was discontinued in 1974 when sales dropped, its engine became the power plant for Volkswagen Type 2s ("Kombis") produced from 1972 to 1979: it continued in modified form in the later "Vanagon" which was air-cooled from 1980 until mid-1983. The engine that superseded the Type 4 engine in late 1983 retained Volkswagen Type 1 architecture, yet featured water-cooled cylinder heads and cylinder jackets. The Wasserboxer, VW speak for a water-cooled, opposed-cylinder (flat or boxer engine), did not enjoy the reputation for longevity that the original air-cooled design had forged. From the very start, the engine suffered cylinder-to-head sealing problems, mostly due to galvanic corrosion, often a result of slack maintenance schedules. Volkswagen discontinued the engine in 1992, upon the introduction of the Eurovan.

The Type 4 engine was also used on the Volkswagen version of the Porsche 914. Volkswagen versions originally came with an 80 hp fuel-injected 1.7 L flat-4 engine based on the Volkswagen air cooled engine. In Europe, the four-cylinder cars were sold as Volkswagen-Porsches, at VW dealerships. This "tainted" the car in the opinion of many automotive critics of that era, and a little of that attitude persists to this day.

Slow sales and rising costs prompted Porsche to discontinue the 914/6 variant in 1972 after producing 3,351 of them; its place in the lineup was filled by a variant powered by a new 95 PS (70 kW; 94 hp) 2.0 L, fuel-injected version of Volkswagen's Type 4 engine in 1973. For 1974, the 1.7 L engine was replaced by a 76 PS (56 kW; 75 hp) 1.8 L, and the new Bosch L-Jetronic fuel injection system was added to American units to help with emissions control. 914 production ended in 1976. The 2.0 L engine continued to be used in the Porsche 912E, which provided an entry-level model until the Porsche 924 was introduced.

For the Volkswagen Type 2, 1972's most prominent change was a bigger engine compartment to fit the larger 1.7 to 2.0 L engines from the VW Type 4, and a redesigned rear end which eliminated the removable rear apron. The air inlets were also enlarged to accommodate the increased cooling air needs of the larger engines.

This all-new, larger engine is commonly called the Type 4 engine as opposed to the previous Type 1 engine first introduced in the Type 1 Beetle. This engine was called "Type 4" because it was originally designed for the Type 4 (411 and 412) automobiles. There is no "Type 2 engine" or "Type 3 engine", because those vehicles did not feature new engine designs when introduced. They used the "Type 1" engine from the Beetle with minor modifications such as rear mount provisions and different cooling shroud arrangements.

In the Type 2, the VW Type 4 engine was an option from 1972. This engine was standard in models destined for the US and Canada. Only with the Type 4 engine did an automatic transmission become available for the first time in 1973. Both engines displaced 1.7 L, rated at 66 PS (49 kW; 65 hp) with the manual transmission and 62 PS (46 kW; 61 hp) with the automatic. The Type 4 engine was enlarged to 1.8 L and 68 PS (50 kW; 67 hp) in 1974 and again to 2.0 L and 70 PS (51 kW; 69 hp) in 1976. As with all Transporter engines, the focus in development was not on power, but on low-end torque. The Type 4 engines were considerably more robust and durable than the Type 1 engines, particularly in transporter service.

The T2c, so called since it got a slightly raised roof — by about 10 cm — in the early 1990s, was built for the South American and Central American markets. The T2c was produced in Mexico until 1991* with the 1.6 L air-cooled Type 1 engine, and from 1991 until 1996 with water-cooled engines from the VW Golf (a VW/Audi 1.4 L). Since 1997, the T2c has been built in Brazil with air-cooled engines for the Brazilian market and with water-cooled engines for the Mexican market, the latter easily identified by their large, black-coloured, front-mounted radiators.

Since production of the original Beetle was halted in late 2003, the T2 remained the only Volkswagen model with the traditional air-cooled, rear-mounted boxer engine when the Brazilian model shifted to water-cooled on December 23, 2005. Previously, the watercooled T2c was sold in Mexico between 1991-2002.

This ones for you Kent.

364 miles, fully packed with all my camping gear. No room left in the back. Final altitude gain of 6,000 feet but many mountains and valleys in between. A minimum of approx 30 miles in 3rd gear. Pretty much keeping it at 60 MPH except when I had to down shift. Now before you start yelling bull $hit you need to understand that you are not the only one that knows how to accurately use a correction factor to compensate for odometer errors. Likewise how to accurately determine the correction factor. Oh-yea, same pump at the beginning and at the end. Almost forgot- 24.4 MPG. And yes, speedo reads in MPH and not KPH. And the gas is U.S. Gallons. And I'm not mathmatically illiterate. Plus the bus has headers. Since you say stock exhaust results in less fuel consumption than headers, wonder what kind of mileage gain it could have gotten?

Of the thousands of vehicle that passed me the only thing I could pass were a few semi's on upgrades. A T-4 passed me but also a beautiful lowered show Split Dormobile passed doing maybe 75. Saw the Splitty later and it had a Porche emblem on the back.
Also ran into a friend with a fully equipped Westy running a 2 liter T-1 with his home brew hydrogen enhancement and his numbers are way up in the thirties.

I heard about a guy who once got something like 116mpg+ in his bone-stock Bus.
