Hello, I don’t want to trigger a war of faith here, but ask my question explicitly to those who have expertise or can help me through their experience. With my Alfa Romeo 147 with 2 liters petrol engine an oil change is due soon and therefore need a tip which oil I should fill in. I bought the car last year with 20000Km, oil change was made fresh (5w 40 filled). As time progresses, there is now an increasing oil consumption I don’t know if the oil is the best choice. But if I drive the motorway then I’ll call the 150 hp. I’m really just trying to reduce the oil consumption and not to save any 1/10 l of petrol. What else could be of interest: the car has been running with LPG for 1000 km. I’m going to have a car with LPG. I would be very pleased to hear your answer.
