My first T4 (3 years, 80TKM, God has blessed him) was satisfied with extremely light right foot on country roads with 11.0l. But of course I did not buy a T4 to test his minimal consumption. Then, Christmas 2001, I left him to my wife and with it his fate. Thanks to the airbags, which all did not trigger. That was cash money. Oh… please don’t misunderstand, I love my wife. Really! Nothing happened to her of course. But I wander away … The second T4 (3 years, 75TKM) is also 11l min. That means, when driving in a grown-up way 13l. Is that the normal value? Does Chiptuning help me? Or should I let my wife drive and then buy an Opel? I would be very grateful for your experience!
