On a gallon-for-gallon basis, ethanol delivers less energy than gasoline. However, today's vehicles are designed to run on gasoline blended with ethanol in small amounts (up to 10%) with no perceptible effect on fuel economy Flex-fuel vehicles designed to run on higher ethanol blends experience reduced miles per gallon, but these engines can be tuned to minimize detrimental effects on fuel economy

Volkswagen claims that the V-10 TDI Touareg will get 28.8 MPG "extra-urban" and 23.2 MPG "combined" according to UK figures. owner of a V-10 TDI Touareg in Florida reports a running average of 19.7 MPG in mixed driving and 28.5 MPG at a constant 50 MPH. See similar questions...

Vehicles usually get between 7 to 13 miles per gallon. This depends of course on gross weight, the vehicle size, the speed that you travel, whether you are towing anything. See similar questions...

The mileage depends on the size of the unit and the dirving conditions. Usually, you will get between 8 and 14 miles per gallon. See similar questions...

Might be due to, colder weather, winter grade gas, dirty PCV valve, dirty EGR, dirty air filter, dirt Mass air flow sensor (there is a spray you can buy to clean it out), dirty fuel injectors, low tire pressure, larger then oem tire size, front and/or rear end needs to be aligned, dirty air filter, weak battery or weak alternator. If you replace or clean any of the above pieces make sure you disconnect the battery for at least 15 minutes so the ECU will recalibrate itself. See similar questions...

That said, on average, Touareg owners have reported about 14 MPG for the V8 in mixed driving. Average in-town mileage for the V8 appears to be about 12. The average reported highway mileage for the V8 is about 18. We have received a report from a V6 Touareg owner who has averaged 14.5 MPG in mixed driving during the first 800 miles.

Yes, but mostly for the better! Folks usually report that their mileage stays the same, or even goes up a few ticks when they get a head/cam package. Note that raising compression will naturally improve your gas mileage as well, due to more efficient combustion. Of course, it will be hard to keep your boot off the gas with your newfound power!

JET Performance Power Tuning does not alter your vehicles calibrations in any way that would hurt fuel economy. Fuel economy will remain virtually the same or may even improve (depending upon specific driving patterns) unless the vehicle is driven in a spirited manner (lead foot). For trucks that tow, JET Performance's Power Tuning is generally closer to the better fuel economy than the stock tuning. See similar questions...

AMSOIL Motor Oils reduce friction and drag better than petroleum oils and other synthetic oils, resulting in significant mileage increases. In a recent 1.2 million mile demonstration, AMSOIL showed a 4.5% increase in gas mileage. Other tests have shown greater increases under certain weather and driving conditions. Every vehicle is different, as are driving habits and conditions, and it is difficult to predict an actual increase. Top See similar questions...

This is a question that comes across just about everyone's mind who is considering making their car faster, and the answer is.... Well, it depends. Generally speaking, when you are putting on various bolt on parts to increase your engine's power out-put, the main way that you are accomplishing this goal is by allowing the engine to operate more efficiently. What you are doing in this case is allowing the engine to pull in or push out, air with less resistance. See similar questions...

YES. We make no guarantees as to how much the cover will play in improving your gas mileage. However, in highway driving, many of our customers have experienced as much as a 2 – 3 miles per gallon improvement. If you use the smaller number of 2 miles per gallon as the figure to calculate cost savings, the savings can add up. For example, if your truck currently gets 16 mpg on the highway without the cover, and gets 18 mpg with the cover, you have improved your gas mileage by 12.5%. See similar questions...

The Longer Answer: A great way to calculate gas mileage for an airplane is to compare it's efficiency to a car. For starters, an airplane flies in a straight line ( as the crow flies, more or less ), while a car must follow the roads, which commonly deviate around both natural and man made obstacles. A 300 mile road trip in a car would typically be reduced by about 15-20% in an airplane. A comparison of a 300 mile trip in a Honda Sedan vs. See similar questions...

Sludge build up causes engines to lose performance because it interferes with the ability of internal parts to operate freely. When oil passages are constricted with sludge, the oil pressure to crucial parts of the engine is reduced, especially to the camshaft and valve train. Emissions are also affected by a dirty engine. Flushing the engine will allow oil to flow more freely throughout the engine. See similar questions...

The poorer the gas mileage a vehicle gets, the more carbon that is produced. Compared to the rest of the world, the U.S. has the worst fuel economy standards, as can be seen in the chart below. In fact, the average fuel economy of cars and light trucks in the U.S. has actually declined from about 26 mpg in 1988 to 24 mpg in 2000 due to increasing vehicle size and power, the rising market share of light trucks, and the lack of tougher fuel economy standards. The U.S. See similar questions...

Besides the obvious FUN of zipping around town, through curves, down straight-a-ways and then coming to a stop on a dime, scooters are EXTREMELY economical. Some scooters get as much as 125 MPG (YES! That’s MILES per gallon!). For the popular TN'G Venice, mileage varies from around 60 mpg to over one hundred mpg, depending on how you ride. See similar questions...

Mileage depends on the size of the motor home, driving conditions, and how you drive the RV. If you drive the RV like you drive your car or truck you will get 7 or less MPG. Generally, you will get between 7 and 11 miles per gallon. You have to train yourself to be easy on that accelerator. See similar questions...
