Civic 06 vti using excesive amount of fuel


The computer will very likely be generating engine fault codes if you have quite excessive consumption and there is no point in guessing what the problem is as there can be numerous causes. You have not mentioned if you have a check engine light showing but if you don't just yet you soon will if the problem persists.

1. Go to a reputable mechanic and have the car scanned for fault codes because it will be very likely throwing some codes if you are having a high engine fuel consumption issue (as opposed to a loss of fuel from the fuel system due to an external fuel leak).

2. On thing you can do yourself is remove the old dusty air filter element in the air intake box ( which no doubt has not been changed since ????) and put in a new OEM air filter unit. A dirty clogged unit will cause your engine to run poorly.

When I fuel up my oil pressure goes up i.e. 1/2 tank of fuel over 80 on the oil guage at same time fuel consumption goes up drasticaly


Adding fuel to the fuel tank is absolutely unrelated to to any change in engine oil pressure.
The oil pressure will be higher when the engine oil is cooler and lower when the engine oil has warmed up.

If you are experiencing abnormally high oil pressure on start up I suspect you are running the incorrect type and grade of oil in the engine. Only use the oil specification(type and grade) listed by the manufacturer for your engine and nothing else.. If you are unsure what that is then it is specified in your owners manual for the vehicle.

High fuel consumption has also nothing to do with your engine oil pressure. If you are experiencing high fuel consumption then please read and examine these factors..........................

Hyundai Tucson 2009 high fuel consumption


There are a lot of factors that may contribute to high fuel consumption. Does the engine run ok during normal operation? Rough idle? Check engine light on? Have the oxygen sensors scanned for operating information to determine if the fuel system is operating effeciently by a qualified service center. These sensors monitor the effeciency of the fuel system

My Hyundai 1999 model CHECK ENGINE LIGHT IS ALWAYS ON AND THE FUEL CONSUMPTION IS HIGH.


Do you have black smoke or what looks like soot coming out of the tail pipe. The check engine light monitors fuel pressure through the computer and pressure regulator. It will come on if the pump pressure is too high or too low. If the pressure regulator is faulty it could cause excessive fuel consumption,

High mileage car. Low quality Kenyan fuel. Low on


High on mileage means that the engine has done a lot of work, possible that the compression is down, need to check if this is below level, if there is oil used in excess then the engine needs an overhauling subject to the cost estimated.

Cant compromise on bad fuel as this will bring down the power of the engine.
High fule consumption means poor setting so fuel and ignition , check fuel settings- pump calibration and timing.

High fuel consumption


change o2 sensors every 60,000 miles and use iridium plugs they will outlast engine.
check engine light will not come on until sensors are completely shot,this also goes for your mass air flow,had same issues with 99 beetle happened at 80,000 miles,changed all three items ended up with 35mpg after getting 24mpg before fix.parts are cheap on ebay.
