Volkswagen were built for abuse, especially the diesels. That's why so many have made it to 500k kms even with a dozen over-due oil changes. I'd like to see engines today last that long. Today its all about the now, repalce it when it breaks, and don't worry about three years from now when your engine needs a new crank at 65,000kms
I drove 200 miles in fourth gear with a close ratio GTI trans up on the fuel limiter (55mph) the whole way with no issues
