What’s interesting is that what was considered “standard” tension for an oil ring for a street engine has changed significantly in the last 20 years. 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.
