Hi,
I make the scrapers referenced. There is a lot of misinformation out there.
For example, in ConnClark's engine, Mercedes engineering includes five crank scrapers in the floor of the pan.
In my Mercedes diesel (300 SDL), I often cruise at 3000 RPM. That is well within the effective range of a scraper at cruising conditions.
