– avoid short trips;
– use 0W30 or 0W40 (VW 502.00) oil, because it reaches faster the chain tensioner;
– change the oil every 15.000km;
– when the engine is cold, don’t rev it over 2500 rpm;
– when the engine is cold and at the start it does the warming process for the catalyst (1100/1200 rpm for about 30 seconds), wait for it to be completed, before moving the vehicle;
– after a long trip, wait almost 30 seconds/1 minute, before switching off the engine;
– use at minimum 95 RON fuel , but sometimes use 98/100 RON fuel to clean the injection system."
