It's like a dirty joke that started back in the 40's and the great grandkids are still telling it today. The Pennzoil rumor will be here 60 years from now if we still have oil.
strombony, you have used Pennzoil for years, ever had a sludge problem? Maybe you should set the trend and your friends do what you do.
But, if you decide to use the Valvoline or Havoline more power to you, I'm sure it will work just fine. But, I cannot answer PM's about either because I have never used them (and never will) and I have never worked for either or have any connections with either.
It's just oil, sleep well at night.
