Re: What oil do you use in your V8 Packard?

Hello Everyone,
It's been awhile since I've posted to this NG, but I still lurk from time to time. Working 50+ hours per week nowdays, I don't get much time for anything.

I have used Mobil 1, 15W50 now for about ten years and 80,000 miles in one 352 engine, and six years and 40,000 in another 352 (both engines in 1956 Stude Golden Hawks). I also change the oil and filter every 10,000 miles.

When I pulled the oil pan on the first car to install a Melling oil pump after around 75,000 miles, I removed the main-caps and checked to see how the MBs were wearing. They all looked like they had maybe 5,000 miles on them. Just about every Packard V8 I have torn down (maybe a dozen) had the lower center main worn into the bronze, and similar wear on #2 and 4.

I am convinced the oil zinc hype is not an issue, at least on my cars.

Oh, by the way, I LOVE the Melling pump!!!
