I was talking to a friend of mine today who is excited about me getting the 71. He's a mopar guy, he runs a 66 coronet with a 318 and a 70 dart with a 340.
He showed concern when I told him I using Mobil 1.
His claim is that all modern oils have little if no zinc and that our older engines have flat tappet lifters.
He further warned that these non rollers would not be protected with modern oil w/o zinc.
What y'all think?
