oil is too thin and want to move up to a 30 or 40 weight oil for "better protection" might want to consider this:
"Contributing factors that can cause oil pressure and lubrication problems in an engine include:
5. Bearing clearances too tight for the oil viscosity being used. Late model engines such as a Chevy LS or Ford modular V8 with tighter main and rod bearing clearances of .0015˝ to .002˝ usually require a thin multi-viscosity motor oil such as 5W-20. Fill the crankcase with a relatively thick racing oil and you’ll have problems right from the start. Tighter bearing clearances require thinner oils..." https://www.enginebuildermag.com/2017/03/engine-bearing-technology-spin-spun-bearings/
