Guys I've a VW Multivan 5cylinder engine and the driver keeps complaining of high fuel consumption. I am bent on changing the engine to i4 if I can't bring the fuel consumption down. It's newly imported and I only did the routine servicing including on the nozzles.

What more can I do pls.

Gazzuzz pls help.

GAZZUZZ:


I'm not a fan of VW, but more detail is required on the description of the vehicle.

Meanwhile, if it is fuel injection, the normal rules will apply for good fuel economy.

1. Temp should hover between 90-98degrees

2. O2 sensors should be functional.

3. M.A.F (airflow meter) should give out accurate readings.

4. C.T.S (coolant temperature sensor) should be functional.

5. Wheels should be free to turn, and not held bay the braking system or by faulty bearings.

6. Aerodynamics should be factory standard. putting larger wheels in front of a car, or carrying walls on top the car will mess up the flow of wind, and your throttle angle will always be higher when driving trying to overcome wind resistance.

That's all I can remember for now, overall, take your vehicle to a mechanic that has modern day diagnostic equipment.

Good luck
