Valvoline VR-1 vs. Lucas Hot Rod oil

Viscosity and flow don't really matter in the real world. I have never had a problem with oil up to 20w50 and SAE 30. No wear at all, over decades and 250,000 miles. And some of those vehicles were modern designs claiming I had to use light oils. Nothing gets babied in my garage. Isky will not warranty their flat tappet cams if you use light oil. You can use whatever you want. I would be a fool to change what I am doing. Use good oil, use a good filter, keep it full, and change it.

Same here have always ran 30 straight oil in my 360 and the loved/hated 292 mopar cam. Never a problem. Got this oil weight idea from my dad he always ran this weight in his 1976 ramcharger 318 this engine still runs like when it was new!! 250,000++ miles never been apart still factory rings bearings cam rockers, everything except valve seals!! We are believers in this single weight oil.
