Millions of drivers waste fuel needlessly every day, without even realizing it. Whether by carrying around extra weight or running a vehicle that’s in need of maintenance, bad fuel mileage often creeps up slowly – swilling away your hard-earned money, and contributing to excessive emissions. If you don’t monitor your vehicle’s fuel consumption regularly, increased fuel consumption can be even harder to detect.
In these trying economic times in our country, the last thing you want is a car that drinks fuel and burns holes in you pocket. Lets skip to the details



Air Filter

Do you remember the last time you changed or checked your air filter? If not, it’s probably overdue for some attention. Most drivers should follow a regular maintenance schedule for air filter replacement, increasing filter change frequency even further if they often tow, or drive on dusty, dirty roads. A clogged air filter makes it harder for your engine to breathe, which can burn up to 30 percent more fuel. Other negative side effects of a clogged air filter include reduced performance, and the increased likelihood of burning oil. Thankfully, changing an air filter on most cars or trucks is one of the easiest and least-expensive maintenance jobs.



Tires

This is true especially for vehicles we call jeeps here in naija. Do your tires match the way you use your vehicle? Do you have a car or 4x4 with an aggressive, blocky off-road or mud tire, even though you off-road mildly, if at all? A sport-oriented high-performance tire on your commuter? Specialty tires have a role in increasing the traction, grip and durability of your vehicle in certain scenarios, but running an oversized off-road tire or high-grip sport tire on the road can waste fuel in a serious way. Next time you need a new set of tires, consider how often you’ll use your truck off-road or what level of performance you really need, remembering that less aggressive tires are typically easier on fuel.



Fuel Injectors

Few parts of your vehicle’s engine can wreak havoc on fuel mileage like a bad fuel injector. Especially with the quality of fuel sold in some shady filling stations all over the country. Over time, these precisely-calibrated parts can become clogged, blocked, experience leakage, or otherwise malfunction and wear out—which messes up the efficient combustion process engineered into your engine. A fresh set of injectors can bring an old, higher-mileage engine back to life, though injector replacement is typically only required in severe cases. In many other cases, a simple fuel injector cleaner treatment, used occasionally, is all that’s needed to keep your car’s injectors clean, efficient and in proper working order. in short, replace your injectors if your mechanic says it’s necessary, and always keep your injectors clean by pouring an occasional bottle of fuel injector cleaner into your fuel tank. They are available in most filing stations
