The days are long gone when a special low viscosity oil was needed for the early life of the engine. Racing the engine when it's cold will do far more damage than will be avoided by keeping to standard oil changes. The recommendation to change oil early is just playing to yours and other's anxieties.
I agree. Back in the 70's engineering tolerances were no where near as good as today. Engines then needed de coking and re bores under 100 k miles. When did you hear of a modern engine needing such treatment
Engineering in the engines and the lubricants has moved on in leaps and bounds
In the end though it's your money
