Hi together! Especially to those who, like me, have the Ier Yaris. Which engine oil do you drive, already changed (viscosity, not the oil, is clear or ) and what experiences did you have with it? I will change next week. Have since I bought it (Nov 06) 10 W 40 in it and will change to 5 W 30. Meaningful or rather not? The whole then Castrol Magnatec 5 W 30. Have always had good experiences with Castrol at the mopped. Could someone ever lay of course e explain what the numbers (10 W 40, 5 W 30, 0 W 60 etc) mean? I know where you can switch to where, but I don’t know what the numbers mean. Thx Greetze
