If you look at the accompanying chart, you can see that the tension produced by the older 3/16-inch oil rings used in a 1/16-, 1/16-, 3/16-inch ring package is fairly high at 20 lbf. The slightly smaller 3.0mm ring package used in a 2000-era LS1 for example is rated at only 10 lbf. Lots of subtle things about ring packages. Gas porting, vacuum pump use, thin, thick, etc. Use of Napier "scraper" second ring with lower tension oil ring... And one company's "std" oil ring tension is different from another... and maybe even different then that company used 15 years ago.
