Binding brakes, choke sticking, clogged air filter, fuel leak, injectors (if fitted), slipping clutch (manual), transmission slip (auto). too much right foot. Kids taking the car when you are asleep.
High fuel consumption on an EFI could be caused by a bad O2 sensor. Another reason for high fuel consumption is a dirty air filter or oil filter that needs to be changed. Electronic Fuel Injection vehicles are also famous for clogged fuel injectors.
not much spoilers are only effective at very high speeds
High fuel consumption
Yes but not by much.
open manifold.
A GPS tracker has very little o do with fuel consumption. Using a GPS will, however, allow you to plan the shortest route to your destination thereby reducing the fuel consumption.

There are several causes for high fuel consumption in a diesel engine. These include a difference in the weight of the vehicle, increased usage of air conditioning, and a difference in tire pressure.
Yes it sure can.
Several problems can cause high fuel consumption. An engine that needs a tune up, a slipping transmission or a problem with a sensor giving bad information to the computer can all cause low fuel economy.
The 2013 Toyota Tacoma 4x4 has a very high rating for being fuel efficient. Since fuel consumption is the biggest cost is running a 4x4 truck, this would make it very economical.
generally speaking, fuel consumption is higher in low gears because the rpm of the engine is higher. Performance is measured in kilometers/gallon. You have to consider that cars are designed for optimum performance when you drive at around 80 km/hr. For each car there is an optimum ratio distance/fuel consumption.
