Question about 2004 BMW X5 3.0i

Sudden increase of 1l per 100km after oil and air filter change

I just had my car oil service and air filter replaced and noticed that my consumption is all over the place. For 2 years I had a steady 8.2l/100km. Took it back to the mechanic and they checked the air filter and all appears ok. What else could the reason be?

SOURCE: during slow, steady acceleration, car feels like it is hesitating

That was just a generic answer I do not know your particular car. Back in the day we put oil around the intake gaskets and if the engine  speed increased or steaded we knew that we had found it. I also could be other things.  Have you tried Carb/injector cleaner in with the gasoline? A vacuum leak could be too small to show on a vacuum gage but a person could look for or at least confirm a leak with the gage. Sorry I can not be of more help.

SOURCE: High oil Consumption, BMW M5

Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!

SOURCE: Battery keeps dieing..jump start and runs for a few days and dies

Humm ...Didn't die before the accident? now dies? BMW has good mechanics,but could not find any problem???. I gota think that it is related to the rear ending,but how? I would look for loose connections, Battery Ground that might have been removed before welding.Battery terminals, Any primary connections that may not be making 100% contact . It's worth a try.Good Luck

The performance on an 2011 opel insignia has gone from 5,5 ltr per 100km to 6.3 per 100 km ... recent service oil change filter change ... even blew out the particle filter... any solutions


Best would be to add a air/fuel meter and see what's going on. O2 sensors, coolant temp sensor, degraded plug/wires, different oil, right foot got heavier.

High fuel consumption noticed


Hi Samuel, Have a diagnostic scan carried out on the vehicle. If it does not record any faults have a service carried out, making sure to replace the fuel filter, air filter, oil filter and to use a good quality engine oil. Have the spark plugs replaced and a full tune up carried out. Your problem has no easy answer. An increase in fuel consumption can be for many different reasons. If the fuel filter has become partially blocked you will press your foot harder to get the required performance. It can be related to brakes binding, or worn wheel bearings. An increased fuel consumption can be related to different tyres with different tread patterns having been fitted or even incorrect tyre pressures. It can be related to bad wheel alignment. It can be related to a greater load of out put on the alternator or AC compressor output load. Let me have some more details and we'll see what we can check and hopefully solve the problem.

Only the air filter would come into play, if you
have created vacuum leaks in the ducting & thru
unmetered air

Maybe unrelated issues you have there before

The upstream O2 Sensors could be replaced at
100,000 miles & you could look at fuel trim on a
road test

Need new spark plugs every 3 years

Clean the MAF Sensor

Fuel consumption increasing, now averaging +15 l/100km. Notice engine has a whine to it.


Clean your throttle body for starters. The whine could be a multitude of things, but wouldn't contribute to the loss of fuel. Also, replace your spark plugs with AC Delco 43-103, other Platinum plugs don't work well with Envoys/Trailblazers. Also, probably time for an 02 sensor change, the one upstream in the engine compartment. These things will all help increase fuel mileage.

If you want more mileage...us SEAFOAM in the brake booster, and gas tank to clean the carbon out, but after you run a tank, might as well replace the fuel filter too.

My 2001 kia rio 1.3l consumes so much gas at about 9 kilometers per liter. I believe they can go upto 14-15 kph per liter. What should i do to minimize gas consumption?


You can over-inflate your tires by about 8%, use a K&N air filter, drive 15 kph slower on the highway, accelerate slowly and never accelerate uphill, draft behind larger vehicles, regular maintenance (oil changes, spark plugs, wires, filters), use a fuel system cleaner every oil change. These can increase your fuel economy drastically, but if you are still noticing poor fuel economy you should have the car checked by a mechanic for what might be causing the high fuel consumption.

i hope this helps

More fuel consumpion


No codes? Checklist: MAF: Mass Air Flow Sensor, MAP: Manifold Absolute Pressure Sensor, Engine Valves/Low cylinder compression, Fuel Injectors, Fuel Pressure, Tire pressure, vacuum leak(s), PCV: Polution Control Valve, Purge Control Solenoid Valve PCSV stuck open/leaking, Intake Air Hose leaking, Engine Coolant Temperature Sensor, Intake Air Temperature Sensor, etc. etc. etc..
Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

High gas mileage (15- 20 l per 100km)


try changing the oil also it will cause the engine to burn more fuel with bad oil because it gets hot and evaporates it alot more

Do you remember by chance speed vs RPM before & after work done? for example : before was 2000 RPM @ 60 MPH. Now 2200 RPM @ 60MPH ? May be coincidence, and transmission not shifting to overdrive or high gear.
