I don't think the fear mongering is necessary. Most North Americans drive there cars lightly, even sports cars.
Better advise would be that it's a good practice even with cars that are driven lightly to still be rev'd close to red line in a lower gear on occasion once up to temperature.
If intake valve deposits are an issue with this engine I'd suggest using an oil with a very low deposit rating such as Castrol Edge 5W-30.
In a spec 502.00 oil, I wouldn't use anything heavier than M1 0W-40 which means no other 40 grade oil.
Castrol Edge 5W30 first is not Low SAPS oil, second,
it is too thin for any European car.
Kinda bold absolute statement, isn't it? Considering VW spec 503.01/506.01 is 0w30.
Also, 504.00/507.00 is 5w30.
Yes, you can buy Castrol Professional Longlife III in the US either at dealerships or online VW parts places (specifically TDI's).
Look at HTHS and cst that Castrol 5W30 Edge has and for example GC!
GC as any Euro spec 0W30 or 5W30 are thick 30 oils, with cst of minimum 11.5 and HTHS minimum 3.5.
VW 502.00/506.01/503.01/504.00/507.00 etc, only thing common they have with American castrol 5W30 are number and similar bottle
