Gotta contradict you here.... First, the quality of the oil may have some bearing on the longevity of an engine, BUT....more importantly, look at the difference in times. Back in the '60s, roads were mostly 2 lanes. Not a lot of expressways. That was tough on a powertrain. Also, at reasonable "highway" speeds, the engines were running at 3500 rpm. Nowadays, we are running on relatively smooth expressways, at 65 mph or so, and turning 1700 to 1900 rpm. BIG DIFFERENCE!!!!! Thank overdrives and locking converters for a lot of that.
And a side note.... spinning your wheels on a REAR WHEEL DRIVE car with a V8 engine was nothing to brag about. Between lack of traction in the rear, bias ply tires, and a grabby clutch, I could do the same with my 170 cubic inch Mercury Comet with a 4-speed trans. I just didn't because I had to pay for my own tires. That also made for treacherous driving on slippery roads.
