I have been advised that I should use a break-in oil such as Gibs break-in oil for my rebuilt blower 276 flatty. I can’t seem to find whether or not it is indeed the best to use for break-in or any different than using VR-1 for both initial and after break-in.

I could also use some advice for the Ross piston with metric rings. Any special tricks to get them installed properly? I have read and studied the instruction sheets.

Any advice would be appreciated. Thanks

It is my understanding that running in oil has no friction modifying additives; it is plain mineral oil, designed to allow the rings to quickly bed in. I always change that oil after the first 50 odd miles, thereafter run the oil of your choice.
My experience with those metric rings is that the top rings cannot be filed with a regular file should you need to open up the gap. You'll need a special ring gapping thingee with an abrasive disc that you rotate against the end[s] of ring

I just installed a set in an engine I am building. I did use ring gap grinder. No problems and the installation was straight forward. I will say I did notice less drag when turning the engine over. I have always used conventional oil right from startup and have never had anyone complain that the rings did not seat.

I'm down under and so probably have different oil suppliers than you guys. The running in oil is marketed by Penrite [Ozzie company], and is called running in oil.
The 'thingee' I referred to is a gap grinder.
