How economically to operate the car

THE GENERAL DATA

The fuel expense, loading on environment, deterioration of the engine, brake mechanisms and tyres depend on many factors.

Individual style of driving

Substantially defines expenses on operation of the car and size of toxic and noise loading on environment.

He warm up the engine, being at a stop.

Process of warming up of the engine idling lasts very long, and deterioration of the engine and the fuel expense at warming up are especially great. Therefore at once after engine start begin movement, avoiding thus high turns of the engine.

Avoid car dispersal by full pressing an accelerator pedal.

By full pressing a pedal of an accelerator not only essentially increases ся the fuel expense, but also loading on environment increases, and also deterioration of units and car knots is accelerated.

Do not move with unduly high turns of the engine – whenever possible pass to higher transfer and subsequently only earlier then be switched to lower transfer when the engine cannot further is equal work.

For example, the expense of fuel on 2nd transfer twice above the fuel expense on the higher transfer. Besides, thanks to the reduced turns of the engine also the noise level also decreases.

Whenever possible do not move with the maximum speed.

The fuel expense, the maintenance of harmful substances in the fulfilled gases and noise level repeatedly increase at high speed of movement. If to move with the speed approximately equal to three quarters of the maximum speed, the fuel expense decreases approximately half. And the gain in time as practice shows, is very insignificant.

Move whenever possible in regular intervals and try to foresee the further development of road conditions.

Superfluous braking and accelerations which it would be possible to avoid, inevitably lead to the big expense of fuel and the raised loading on environment.

Switch off the engine in those road situations when it is necessary to wait long enough time for possibility to continue movement.

Features of traffic conditions

Also, naturally, influence the fuel expense.

To the raised expense of fuel, for example, conduct:

 – High traffic density, especially in city conditions with a considerable quantity of traffic lights;
 – Movement with frequent short-term parking that inevitably conducts to a considerable quantity of starts of the engine and its long work in not completely heated-up condition;
 – Movement in a stopper on the lowest transfers, the compelled frequent change of number of turns of the engine in relation to the passed distance.

By careful planning of a route of a trip try to avoid whenever possible movement in adverse conditions: in a column, with frequent stops etc.

Certainly that the fuel expense depends as well on those factors which the driver cannot affect in any way. For example, quite normally that the expense of fuel in the winter or in difficult traffic conditions (a bad condition of a road covering, trailer towage, etc.) raises.

Preconditions of technical character

To the economical expense of fuel and profitability of operation of your car as a whole are put at factory. The special attention has been given whenever possible to the minimum negative influence of the car on environment. That all numerous merits of your car in the best way to use now and to keep them on the future, it is necessary to follow the recommendations listed more low.

Cars without каталитических neutralizers in interests of protection of environment should be maintained also whenever possible on неэтилированном gasoline.

All provided works on car maintenance service are necessary for spending in strict conformity with "the Service book".

Regular service at the service enterprises guarantees a Volkswagen not only constant working capacity and durability of your car, but also rather low working costs, small loading on environment.

Check pressure in tyres once a month.

Because of the lowered pressure in tyres resistance качению wheels raises. Thereof not only the fuel expense grows, but also deterioration of tyres increases and road performance of the car worsens.

It is not necessary to carry constantly with itself unnecessary subjects in a car luggage space.

The size of weight of the car especially strongly influences the expense of fuel in the conditions of the city movement characterised by frequent accelerations.

At once remove a luggage carrier from a car roof if in it there is no necessity more.

It is necessary, because at high speed of movement the raised resistance of air conducts to considerable growth of the expense of fuel.

Onboard consumers of the electric power include only when in it there is a crying need.

Heating of back glass, additional headlights, the fan of system of ventilation and heating, climatic installation – all of them consume the big current. Because of the raised loading on the generator the fuel expense increases. Heating of back glass within ten hours results, for example, in the expense of superfluous litre of fuel.

Constantly supervise the fuel expense.

At each fuelling it is necessary to count up the specific expense of fuel. Thanks to it separate malfunctions in work of units and knots автомоби can be revealed at an early stage
It is necessary to check oil level in the engine at each refuelling of the car by fuel.

The engine oil expense substantially depends on loading and frequency of rotation of the engine. It is defined as well by style of driving of the car and can reach 1 l/1000 of km.

Quite normally that the expense of engine oil of the new engine only after certain run reaches the least value. Therefore it is definitively possible to judge the engine oil expense only after run about 5000 km.

It is equally fair and concerning the fuel expense, and concerning capacity of the engine.

Reliable work of the device for neutralisation of the fulfilled gases

Has crucial importance from the point of view of maintenance of is minimum possible damage from operation of the car for environment.

Therefore it is necessary to observe following requirements strictly:

Cars with каталитическим neutralizer should be maintained only on неэтилированном gasoline.

Equipped каталитическим neutralizer, it is not necessary to spend a fuel tank of the car never up to the end. Because of possible thus to non-uniformity of receipt of fuel in the engine possibly occurrence of faults in its work that leads to hit of not burnt down fuel in каталитический neutralizer. It can become the reason of an overheat and the subsequent failure каталитическо го neutralizer.

When during movement faults in work of the engine decrease in its capacity and non-uniformity of a course are marked then, probably there is a malfunction in ignition system. In this case not burnt down fuel can get to an exhaust system and further in atmosphere. Damage каталитического neutralizer owing to its overheat is besides possible. It is necessary to lower speed of movement immediately. Malfunction should be eliminated in the nearest service enterprise a Volkswagen.

It is not necessary to pour oil in the engine.

It is impossible to tow the car for the purpose of engine start on distance more than 50 m.

The prevention

Owing to a heat каталитического neutralizer that can be marked in especially adverse conditions of its work, the car should so be parked whenever possible that каталитический neutralizer did not adjoin to inflammable materials.

Never apply additional corrosion-resistant coatings to protection of exhaust pipes of the muffler, каталитического neutralizer or heat-shielding screens. During movement anticorrosive structures can ignite.

---

Even in case of normal work каталитического neutralizer under certain conditions exhaust gases can have a sulphur smell.

It can be caused the raised maintenance of sulphur in fuel.

Here change of mark of gasoline or car refuelling неэтилированным gasoline of mark super frequently helps.
