Jeff , When I came to this side of the ocean 5 years a go The car dealer here ( bought a new Hyundai ) he tried to convince me that I had to do a oil change every 5000 km. When I asked why ?? back home I only changed oil once a year . Oh well here everything is different . Yea OK but the ASTM spec's here are the same as were I am from. I also told him that I have always bought new cars since the last 35 years and never had a oil related problem and drove an average of 25000 km a year traded my cars in at an average km reading around 250000 km NEVER any problem.
So Mr dealer all the stories about changing oil every 3 or 5 thousand miles ! I considder BS.
