The only 60 through 70s sludge was in engines that weren't maintained.Not bad at all. No real sludge. I'd use mobil 1 high mileage as its claimed to be a cleaning oil. You could run a 10w 40 with kreen for an oci. But really there is not much there, compared to the late 70's 80's sludge. Just good oil changed regularly will do a lot. NO ATF.
