Regular gasoline or super gasoline?
The names of gasoline "standard" and "super" are actually not true, since both types of fuel are of the same quality. They do not differ in evaporation (very...

Fuel consumption
Standardized consumption When it comes to fuel consumption, the term "standard consumption" often appears. It is determined on the basis of test conditions in...

This way you will save in economy mode
Fuel consumption is indeed favourable at low revs and high engine loads. This kind of driving style was dismissed as "torturing the engine". But all the...

Fuel tank — general information
The fuel tank in the Vectra holds 60 liters and is made of synthetic material. The fuel tank in a car must meet high safety requirements, because in an...

What is the purpose of fuel tank ventilation?
In order to ensure a continuous supply of fuel, the fuel tank must be ventilated: air must enter the tank in the same volume as the fuel is consumed, otherwise...

Fuel quantity indicator sensor
The fuel level sensor is installed in the middle of the fuel tank on the left next to the fuel pump. It sends a signal to the indicator about the amount of...

Fuel lines
The fuel system of our fuel injection engines must withstand operating pressures of up to 3 bar. The hoses are therefore made of particularly...

Checking the fuel system for leaks
Maintenance work If there is a smell of gasoline in the place where the car is parked, then there is a leak somewhere in the fuel line or in some unit of the...

Electric fuel pump
The Vectra has a so-called twin-turbine pump. It is installed directly in the fuel tank. The pump consists of an electric motor and two turbine wheels, which...

Removal the fuel pump
Empty the fuel tank as much as possible while driving. Drain the fuel if necessary. Where possible, relieve pressure in the fuel lines using a test connection...

Replacing the fuel filter
Maintenance work The injection system is sensitive to contamination, so the fuel is passed through a special filter. Especially when refuelling, from a freshly...

Removal the air filter insert
Loosen the hose clamp and remove the air intake hose from the air cleaner housing cover. Release the five clamps on the air cleaner cover. If the clamps do not...

Blowing out the air filter insert
Maintenance work Every 15,000 km or annually, we recommend that you clean the paper filter insert from coarse dirt. When traveling on extremely dusty roads,...

Replacing the air filter
Maintenance work Opel recommends replacing the filter insert every 30,000 km. This is sufficient under normal driving conditions; the insert is cleaned...

Preheating of intake air
The air sucked into the combustible mixture must not be too cold or too hot. Therefore, in 8-valve 1.6 l engines with central injection, under certain...

Help with air filter problems
Preheating of intake air Functional testing with auxiliary means To check the intake air preheating, disconnect the vacuum line to the control flap on the...

Intake manifold heating
Fuel mixed into the air by central injection tends to settle on the walls of the four-channel intake manifold, especially when the engine is cold. Heating the...

Throttle body heating
To improve the performance and exhaust gas composition in our Vectra with four-point injection (all 16V), the throttle body is heated by the coolant of the...
