FEELING RAIL GAP
It can be very difficult to check end gap on oil ring rails or gapless ring rails. I opened up the gap on a top ring of the appropriate bore size and squared it in the cylinder with a tool made from a scrap sleeve. Just set the rails on the top ring and they're square in the bore. Now it's much easier to get a feeler gauge in for an accurate measure.
Viscosity (a fluid's resistance to flow) is rated at 0° F (represented by the number preceding the "W" [for Winter]) and at 212° F (represented by the second number in the viscosity designation). So 10W-30 oil has less viscosity when cold and hot than does 20W-50. Motor oil thins as it heats and thickens as it cools...
