It's been a few years since I last called the Shell Answer Man hotline, the 800 phone number. Rotella 15W-40 straight oil, not synthetic blend, was 1200 parts per million ZDDP, Your Delvac at 1012? PPM is in the same range, should be fine to use in old ag equipment without today's common roller rocker arms and valve lifters.
I've used Rotella in my 1950's vintage Farmalls and Air cooled Kohlers in Cub Cadets since 1996 when I got my brand new F-250 diesel, that strangely enough, doesn't need that much ZDDP because it has roller rockers and cam followers.
I had a brand new Mustang GT that I drove 700 miles to a NASCAR race in 1988, car wasn't completely broke in, burned a little oil, I used 10W-40 Valvoline in it, I stopped at 40-50 gas stations and truck stops Sunday night on the way home looking for a quart of Valvoline, not a quart for sale anywhere, but could have bought a semi-truck load of Pennzoil. When I got home at 3AM I put two quarts of Valvoline in the car. Since that night in 1988 I use the oil brand that's good and most readily available. Even most grocery stores sell quarts of Rotella! If Delvac was that easy to find I would use it in a heartbeat. I use Mobil 1 synthetic in my cars and pickups.
