I just bought a Toyota Avalon 2001 model. The fuel consumption is crazy. And it also emits black smoke when the engine is fired. I am wondering what the issue is exactly. When I drove from Laagos to Bayelsa, I used two full tanks of fuel which is about 160 liters. Pls I need help. I service the car regularly |

Hi Sienna, Please help! My Toyota Sienna 1999 CE model consumes a lot of fuel. No error codes after running OBD II scan. Just bought it november last year and discovered the silencer, from the manifold end to the tail pipe has a lot of rust. All noticed leakages on the silencer has been welded yet fuel consumption is still high. Catalyst has bbeen checked and still intact. What do I do to reduce the fuel consumption or bring it back to normal. Also the injector and nozzle are working well. |

It will cause slightly higher fuel consumption in traffic / slow driving. But will be better on fuel at highway speeds. |

@siena[b][/b] I just bought 1999 toyota camry and discovered the fuel consumption is outrageous. I'm scared about quack mechanics touching anytin on the car, however these are my observations: Both fans come on immediately d key is turn to on position The temperature hardly leave the lower limit position. It also indicates check engine light. What do u think I do cos I changed car simply because my former car consumes fuel excessively and my mechanics help to spoil it further and I'm really scared allowing any of them touching my car |

I saw your posts on nairaland on the issue of fuel consumption. I've an Avensis 05 model. I use 205/65 tyres instead of 195. I've noticed its mpg is not constant and depends on where fuel is bought. I do between 90-120km/hr and travel a lot. From Keffi to Akure I use about 37litres which gives about 13km/litre but anytime I buy fuel at Akure NNPC Mega station I achieve less. I've noticed this over 4times on my journey through that route. What can be responsible for this? Type of fuel? I need this car to achieve about 14km/l on a highway what can I do to achieve this? Do I need to change the tyres? How do one know when the airflow meter is bad? How much does corolla auto transmission go for now? Mine is the 2007 japan xli model 1.6l engine. Thanks and God bless. 1 Like |

An unexplained increase in fuel consumption by your car costs you money and is a symptom of potentially expensive problems. Identifying the reasons your car is burning more gas than it should and correcting them will save you money and help you to avoid costly repairs. Familiarizing yourself with the more common causes of poor fuel economy is a smart way to help keep your car running as economically and efficiently as possible. 1. Fuel leaks Fuel leaks can cause a sudden drop in fuel economy and create a potentially dangerous fire hazard. You should suspect a fuel leak if you smell a strong gasoline odor near the vehicle or notice unexplained wet spots on the ground underneath your car. 2. Dragging brakes Brakes can malfunction, causing a condition where they do not fully release. This increases the load on the engine, forcing it to work harder and burn more gas. Suspect dragging brakes if you notice excessive gray dust on wheels and tires, or the accelerator must be depressed farther than usual to achieve normal driving speeds. 3. Vacuum leaks Vacuum leaks cause a car to burn more gas than it should by introducing excessive air into the engine, unbalancing the fuel to air mixture. The engine compensates for this uneven fuel to air ratio by introducing more gasoline into the mixture to compensate for the increased air volume. A vacuum leak will typically cause rough idle, poor acceleration and misfires at operating speeds. Cracked hoses, worn out gaskets and loose fittings are common causes of vacuum leaks. 4. Clogged air filter Air filters trap dirt particles, preventing them from entering the engine. Over time the air filter will become clogged with dirt particles, reducing its ability to allow the free flow of air into the engine. Symptoms of a clogged air filter are burning more gas than normal and poor acceleration. 5. Worn spark plugs Worn spark plugs reduce an engines ability to burn all of the gas in the combustion chamber. Some of the gas remains unburned and is expelled into the exhaust. This reduces power, causing the vehicle to use more gas to do the same amount of work, lowering fuel efficiency. Worn spark plugs cause misfiring, reduced power, poor acceleration and reduced fuel economy. 6. Underinflated tires Tires that are not fully inflated increase resistance to rolling, requiring more energy to move the car forward. The engine has to work harder to overcome this increased resistance, resulting in the car burning more gas than it should. Tire inflation should be checked regularly with a tire pressure gauge and kept at the manufactures inflation specifications. 7. Driving habits Aggressive driving, jack rabbit starts, exceeding normal speed limits and excessive idling increase fuel consumption and should be avoided. |

Hello guys. I love this thread. Here's my issue. I just bought a honda accord 2008 4cyl and i noticed that fuel consumption is alot higher than my previous 03. It guzzles alot fuel. Each time i accelerate it makes a loud roar like and open air intake, the kind of sound you hear in race cars with turbo chargers. The dealer said it is due to the pimped up exhaust. But i don't hear the sound from the rear but from around the dashboard and below. I also noticed that the air intake pipe that is supposed to run from the front grill on top of the radiator to the air filter is missing. My mech said its a missing catalyst but i suspect it has sometime to do with the missing pipe and the loud roar. Ps i hate noisy cars. Oh and when i accelerate on highways i can literally see the fuel needle drop. Please help. |

klipse: Hello guys. I love this thread. When you say your '08 Honda Accord's gas consumption is high, you need to be more specific. What would you class as high? What engine size is it, and what engine size was your previous '03 model? The roar around the dash area could well be an exhaust leak, that should be checked. The Accord being FWD has a flexi pipe linking the exhaust mid-section to the front, covered with braided steel (in most cases). Make sure the flexi section (corrugated steel) has no cracks. The air intake pipe from the lower section of the airbox to the grille is your cold intake. If it's missing, your engine will be drawing in hot air from the engine bay. Cold air is denser, and allows a more complete fuel burn. It CAN affect gas mileage adversely. I would get it replaced, then re-assess gas consumption. 1 Like |

OP, stop bothering yourself. Nothing is wrong with your car. A 3.0L engine must consume fuel na... The engine is a big engine and requires big food. If you want low consumption consider buying at most, a 1.8L, dats all. Anything from 2.0L upward means you are ready to be purchasing fuel as big ogas do. 1 Like 1 Share |

Rich fuel mixture is caused when the air-fuel ratio is not correct. This is the mass ratio of air to fuel present during combustion. Some symptoms of a rich mixture include excessive soot on the exhaust tip and a noticeable drop in fuel efficiency 1 check the PSI of ur tyres, Mk show it thesame as d car manual specification 2. Use nitrogen in ur tyre instead of regular air, 3. Check ur catalytic converter , Mk sure its not clogged, 4. Check for vacuum leaks, 5. Troubleshoot with obd scan |

@ OP are u sure ur 'akara' (catalyst) have not been removed? If ur check light is on....something might be wrong electrically or ur catalyst tampered with. I knw exactly what I'm saying. Tire size and under inflation actually affects consumption of fuel....but not as bad as the picture u are painting. |

j diadem: [font=Lucida Sans Unicode]In addition to all that has been said, consider the weight of oil used. If intended denotes 20 or 30 weight oil and you fit in 20w-50 or something in that order, you re going to have parasitic drag in your chamber. The oil is too heavy and driveability suffers. Consider fuel treatment/stabiliser also and your source of fuel purchase. You can control and slowly eliminate port fuel deposits by using these treatments every month. If the gasoline sold where you are contains ethanol, in the long run, your vehicle will trap in moisture in the gas chamber that might eventually lead to water. You can figure what might happen over an extended period of time.[/font]not advisable.its scam. |
