Yep that's the thing about older engines/equipment. Their tolerances were nowhere near as exact as the newer stuff. And because of this, could get by with sludge oil lubricating them. I had a guy drop off a 15 yr old MTD with a quantum Briggs motor on it that took me 45 minutes to change the oil because it was the consistency of Elmer's glue. I thought that after I fired it up after filling it with synthetic Rotala it might start gushing!
It's a double edge sword really. The newer stuff performs an unbelievable amount better with smaller displacement/is much more efficient/much much cleaner burning. But they do demand proper maintenance with the proper fluids.
