What role does the engine operating temperature play in excessive fuel use?
If you’re running cold, you’re getting incomplete combustion, black smoke, carbon build up. If you’re running at the right temperature, but not too hot of course, everything should be firing nicely, burning the fuel properly and running efficiently.
High speeds can also lead to excessive fuel use, why is this the case?
If you’re going at high speeds, you’ve got wide open throttle, injectors are pushing as much fuel as they can get through, and you’ve got a high wind pressure. Generally speaking, speeds over 100km will definitely soak up more fuel just from the resistance through the air alone.
Apprentice: How important is turning when it comes to fuel consumption?
Allan: Very important. If you’ve got retarded ignition or faulty chip turning or If someone’s been playing around with the computer itself, your vehicle is definitely going to burn more fuel than it should, and effectively do damage to the motor.
