Yes it DID, back in the '70's.
Only 50 years ago?
I can't go back THAT FAR! But, I do remember about 1975-76. My dad used PZ SAE 30 wt. to break in engines. But, he always told me,"Son, when you start working on your own engines, don't use Pennzoil and QS to run in your engines." The proof was the '72 Gran Torino he bought from my uncle. He used both of those oils and it showed in the 429 sludge monster in the GT. Not changing it often enough contributed to it as well.
LOL well I was putting Pennzoil in my 1969 Chevelle SS in 1969 and had been home from the service for just about a year. I changed my oil every 3000 and never had a problem.
