2008 xlr

so I went to honda service center to have my XLR piston ring replaced. the emission of smoke started when i changed the oil with top1 brand with the belief that it could increase engine performance because it adds lubricity. But I was wrong.

Is it actually true that the emission of smoke indicates of a damaged piston ring?

Making the impossible possible!

If the problem started when you changed the oil, and the new oil is synthetic, that could be the problem. Some engines do not handle synthetic oil well.
Try going back to a premium conventional oil like Honda GN4 and see if the problem corrects itself.
Oil burning can be caused by something as simple as a restricted crankcase breather. Or something more serious, like a worn or damaged oil ring, a scored cylinder, an out of round cylinder bore, or worn valve seals.
Hopefully it is just the deluxe oil you used.
