the cheapest modern day no name oil on the market will get the job done.
Only as long as the engine is designed around the oil.
Chevy put ti rods and ultra light pistons in their modern LS7 small block because the Mobil 1 5w30 they "swear by" as their factory fill oil couldn't maintain adequate film strength in durability testing with more normal weight parts... and that's only a 500 HP (SAE net) hydraulic roller street engine.
And how quickly people seem to forget all the flat-tappet cam failures attributed to the major reduction in zinc, etc., due to the EPA mandating the reduction to save the cat converters.
Well I had 2 1996 vetts both 6sp with the LT4 one with minor upgrades and the other one was pushing 490hp with heavy ol steel rods and regular ol pistons and I beat the he!! out of both of them for years and the Mobil 1 did just fine.
