Hello, I’ve already seen a lot of discussion about the different types of oil. So I would like to hear your opinion: I drive a 156 2.5 V6 with a mileage of 115,000. The last oil change is 15 Tkm and is now so slowly due again. 2 years ago my workshop Selenia 5W30 suggested to me what I have been driving since. Only it consumes so slowly a little bit of it (1/2L to 1000 km). What kind of oil would I use less of your opinion with? Besides, I would like to know if someone would explain to me the meaning of the two…. I look forward to your opinions! Greetings to all infected!!
