5.1. "Juice" with many talents – engine oilIn the further ambassador of this information it becomes clear: oil is an elixir of a youth for an internal combustion engine. The friction and deterioration of pistons, cylinders, and also all locations of bearings krivoshipno-shatunnogo the mechanism and клапанных drives decreases. Besides it engine oil causes consolidation of pistons to walls of cylinders. Arising «взрывообразно» at combustion of a fuel mix gases thanking «an oil lining» almost without loss drawing operate on a cranked shaft. Talents of engine oil far are not settled by it: engine oil takes active part in engine cooling. Besides, it protects the engine from a rust, keeps polluting particles in an equilibrium state, connects a part of chemical products of combustion of fuel.
Comprehensively talented – all-weather engine oil
Modern engine oils are the lubricants made from oil. However before beginning the career as engine oil, the manufacturer of oil adds to them some special additives. In the end of a chain of clarification it makes to 20 % of engine oil. Additives, for example, protect oil from oxidation and protect its foaming at high frequencies of rotation. One of the major additives are Vi-uluchshateli (VI – a viscosity index). The explanatory: VI-additives are long molecular chains which under the influence of heat inflate, and at cooling are again compressed. Thereby VI-additives automatically "regulate" engine oil on engine temperature. At skilful mixing it is possible to unite at once some classes of viscosity. However VI-additives possess also negative property of wearability at heats that leads to loss of the basic share of their influence. Besides, water, fuel and combustion products establish border of service life of engine oil. Liquid mineral oil does not maintain eventually parametres of pressure dominating in the engine and temperature. Therefore regular replacement of oil is not compelled luxury, and simply tehniko-chemical necessity – at least when your engine should function smoothly.
The raised price – synthetic oils with good antifrictional properties
Basically synthetic oils are not "artificial", as well as existing mineral oils, however they are always more expensive. The reason: in synthetic oils the molecular structure of "natural" crude oil at the expense of use of expensive technologies (Cracken) remains, and they mix up with special additives under other recipe. As an equivalent of a high purchase price their manufacturers promise the small expense of oil and fuel, high stability and long firmness: theoretically it means the increased interval of replacement of oil. If you all the same wish to take pleasure in such injecting oil should not is so boundless to exceed and so established Ford the stretched interval of replacement.

Concepts and the norms concerning oil
Viscosity: characterises a measure of fluidity of lubricant oil. In the winter liquid engine oil which at cold start-up gets at once into all places of greasing of the engine, – the first choice. During the summer period plastic engine oil which does not break a lubricant film even at heats, on the contrary, is requested.
Classes of oils it agree SAE (Society of Automotive Engineers, the USA - the Society of autotractor engineers): designates a viscosity class, for example, SAE 5W-30. The less first figure, the flows oil in a cold season (W – winter) is better. Oil with a designation 0W greases at a minus 30 °С, and class oil 5W lifts this value to a minus 25 °С, 15W – accordingly a minus 15 °С. Than more second, especially steady against temperature is considered oil at heats.
ACEA (Association des Constructeuers Europeen dAutomobiles): the European norms entered in 1996 have replaced norms ССМС with oil. For carburettor engines are offered group A1 (the oil saving fuel), А2 (малонагружаемое oil), А3 (oil for work severe conditions). For diesel units the division on В1, В2 and В3 is given here.
ССМС (Committee des Constructeuers dAutomobiles du Marche Commun): the Specification consists of letters G (gasoline) and PD (diesel fuel), and also numbers. The more number, the above quality of oil.
API (American Petroleum Institute): the specification consists of letter S (carburettor engines) and With (diesel engines), and also the subsequent letters. The above this letter costs alphabetically, the above quality of oil. |

Engine oil – "study" on the small press on bank
For your engine Mondeo quite enough traditional all-weather oil. However here it is important to know that this "juice" answers corresponding norms. In cases of doubts request the dealer as it is necessary to judge suitability not on an advertising label on oil bank, and under its maintenance. Therefore attentively read the text printed in small print on bank: Ford recommends for the Mondeo engine oil SAE 5W-30 which corresponds at least to the specification of ASEA А1/В1 and WSS-M2C912-A1 or WSS-M2C913 (diesel oil WSS-M2C913-A or WSS-M2C912-A). If you wish to use other grades of oil they should correspond at least to the specification of ASEA А3/В3. Oils with designation API SC, SD, SE or SF (diesel API CC) can even damage to yours Mondeo.
As soon as lubricant juice will answer the named criteria, it is possible to mix grades of oil of different manufacturers. Thus it is necessary to reckon, however, with that specific properties of initial recipes worsen. Each product is characterised by the specific structure which efficiency at mixing with other oils can weaken. For this reason the combination of mineral and synthetic oil also is not meaningful. Similarly it is impossible to mix pure diesel oils with oils for carburettor engines – at worst it will provoke occurrence of defects of the engine.

Thanks to it you on a right way: engines Mondeo are not necessarily calculated on expensive synthetic oil. Ford recommends for our range of widths engine oils of a class of viscosity SAE 5W-30. |
Absolutely normally – the small expense of oil
A few oils are spent by any engine. Partially it gets to the chamber of combustion and there participates in burning process. Not tight engine, defective linings of cores of the valves, worn out маслосъемные rings, too big backlash between the piston and the cylinder or the big backlash between directing the valve and a valve core lead to growth of a usual standard expense allowance. When the engine of yours Mondeo in a technical order, during the ordered intervals of replacement of oil it is necessary to supplement in extreme cases small quantities of oil (0,25 – 0,5 litres). For diesel engines in this respect also it is not necessary to do exceptions. It concerns all engines only in the event that you regularly spend replacement of oil and do not load the engine at the expense of unreasonably sharp way of driving.
Blue shade of the fulfilled gas – a visual indicator of deterioration
On blue colour of the fulfilled gas it is possible to judge presence of one of specified above defects. However even if oil level regularly keeps to constants, it yet the basis for pleasure. Surpluses of fuel and a water condensate dilute engine oil, and its lubricant properties worsen. First of all during the winter period and mainly at movements on short distances it is possible to observe such phenomenon – the engine less often through a long interval of time reaches all the working temperature and the rests can not burn down. In this case it is necessary to replace oil through shorter intervals; approximately already through 6000 kilometres or time in half a year.
