I was having a low oil pressure issue with my '52 in hot weather using 10W30 and a old mechanic friend suggested using Valvoline racing oil . . .50 weight! It's a high quality oil that does not break down and I've not had any more trouble. She runs quieter, smoother and cooler. Of course she's in the garage in cold weather.
