The SAE classification indicates the viscosity of the engine oil. SAE - Society of Automotive Engineers - Society of Automotive Engineers.
For example, the designation SAE 10 W 40 indicates the following:
- 10 - viscosity of the oil in a cold state. The lower this number, the more fluid the cold oil is.
- W - this symbol indicates the suitability of the oil for operation in winter.
- 40 - viscosity of the oil in a hot state. The higher this number, the thicker the hot oil.
Long life engine oil
POLO engines are factory filled with extended life engine oil. To meet the two-year oil change interval, topping up and changing should only be done with extended life engine oil that meets VW specifications.
You can also use conventional engine oils that meet the requirements of the VW standard. However, in this case, it is necessary to set the service interval indicator to 12 months/15,000 km.
Appointment of VW standard engine oils with extended service life:
VW Standard/Engine Type
- 50300/ Petrol
- 50600/ Diesel (not with injectors)
- 50601/ Diesel (with pump nozzles)
Petrol engines:
A - all-weather low-friction oils for non-regulated service intervals. VW 50300.
Diesel engines:
A - all-weather low-friction oils for non-regulated service intervals. VW 50600 for diesel engines without unit injectors. VW 50601 for diesel engines with unit injectors.
Note: For longer trips or overseas trips in a vehicle with Longlife Service, it is recommended to have a canister with the necessary stock of original engine oil in the luggage compartment. If it is necessary to replenish the oil level, and there is no regular oil with an extended service life, then up to 0.5 liters of VW 50200 standard oil can be added to the gasoline engine. In this case, VW 50500 standard oil can be added to the diesel engine (VW 50501 for diesel engines with unit injectors). At the same time, reprogram the maintenance interval indicator to «nicht flexibel» (regulated) no need.
All-weather engine oil
The engines of IBIZA/CORDOBA vehicles are filled with all-weather engine oil at the factory. For POLO vehicles, the use of such an oil is also allowed, however, the service interval indicator must be reprogrammed from the mode «unregulated» on mode «regulated».
Purpose of VW engine oils:
VW standard/ Engine type
- 50000,50101,50200/ Petrol
- 50500/ Diesel (not with injectors)
- 50501/ Diesel (with pump nozzles)
Petrol engines:
A - all-weather low-friction oils of the VW 50000 standard. Behind the designation of the standard there should be a date not earlier than 1.97.
All-weather low-friction oils of the VW 50200 standard.
B - multigrade oils of the VW 50101 standard. Behind the designation of the standard there should be a date not earlier than 1.97.
All-weather oils of API-SF or API-SG specification. Use these oils only if there are no oils approved by VW.
Diesel engines
A - all-weather low-friction oils of the VW 50000 standard together with the VW 50500 standard. Behind the designation of the standard there should be a date not earlier than 10.97.
B - all-weather oils of the VW 50500, VW 50501 standard. Behind the designation of the standard there should be a date not earlier than 1.97. All-weather oils of the WV50101 standard together with the VW 50500 standard. Behind the designation of the standard there should be a date no earlier than 1.97.
All-weather oils of API-CD specification. Use these oils only as a last resort for topping up.
General engine oil specification
The quality of engine oil is indicated according to the standards of car manufacturers and oils.
The quality of engine oils from American oil manufacturers is indicated by the API system (American Petroleum Institut). The characteristic is given, depending on the circumstances, in two letters. The first letter indicates the scope: S (Service) - used in gasoline engines: C (Commercial) - used in diesel engines. The second letter indicates the quality in alphabetical order. According to the API specification, SL oils for gasoline engines and CF oils for diesel engines have the highest quality. European oil manufacturers classify their oils according to the ACEA specification (Association des Constructeurs Europeens d’Automobiles), which, first of all, takes into account European technologies for the production of engines. Oils for gasoline engines of passenger cars, depending on the quality, are divided into ACEA classes from A1-96 to AZ-96; motor oils for diesel engines belong to classes from B1 -96 to B4-96. Oils of the highest quality for gasoline engines belong to the AZ class, and for diesel engines - to the V3 class. Class B4 oils are designed for diesel engines with direct mixture formation, but can also be used when the oil of class V3 is indicated in the instruction manual. The number 96 indicates the year the ACEA classification began, 1996. Engine oils with a higher year number may also be used.
Oil consumption
In the case of an internal combustion engine, oil consumption refers to the amount of oil that is consumed as a result of the combustion process. In no case should oil consumption be identified with its loss due to leaks in the oil pan, cylinder head cover, etc. Normal oil consumption occurs due to combustion in a smaller amount, depending on the circumstances, in the cylinder, as well as due to the removal of combustion products and wear particles. In addition, the oil ages under the influence of high temperatures and pressures, which it is constantly subjected to in the engine. In addition, oil consumption is influenced by external operating conditions, driving mode, as well as manufacturing tolerances. Oil consumption should be no more than 1.0 liters per 1000 km.
Attention: In no case should the oil level be higher than the Maximal mark. If too much oil has been added, the excess must be drained. Otherwise, the catalytic converter may be damaged, as unburned oil enters the exhaust system.
