Conventional mineral oil based engine oil must comply with VW 501 01. Only then does it have the necessary cleaning properties to prevent the formation of oil sludge.
Easy-flowing oils reduce internal friction in the engine. They must comply with the VW 500 00 standard.
Only in the absence of oils of the above specifications can an all-weather or seasonal oil of the API SF or API SG category be used.
Tip: Factors such as the price or origin of the oil say nothing about its quality!
