Hi
Bearing in mind previous lengthy threads, I approach the subject of oil with some trepidation....
I was advised that if the oil you use is "too good" i.e. designed to reduce bore wear (which includes modern cheap types), the rings take much longer to bed in than they would if a specific running-in oil was used. Maybe in the interests of economy the first very short lived fill could be something cheaper.
I'm sure modern engines don't need this step as everything is made to very fine tolerances, but that's maybe not the case for the parts available for Sevens.
