Six pages in and not one account of a failure...just rumors. Is this "lube shaming" LOL
We've run Penn Grade (old Brad Penn) for years since losing three separate engines to cam failure. The failures sent debris through the engines and required total rebuilds in all cases. This with flat tappet cams. Since switching to Brad Penn, no failures.
Does anyone have a personal experience with a true, oil-related failure due to Penn Grade? I just bought another case of 10W30, and have no plans to change until proven it's not going to work.
You must have missed this reply from Chuck@Best Machine who I trust, same with Todd@ Competition Wedge. Please read.
We stopped using BP years ago. A lot of the Engines that come in for freshen ups that run BP have worn rocker shafts and Piston Pins. We only use Driven Brand Oil, every Big Block we Dyno has BR50 in it. In a lot of our high HP Drag engine we use XP3 after dyno but in most cases the HR series oil is a good choice. We use the 15/50 in our bracket style engines.
