Thanks for info on oil and oil pressure questions

[Lee1969]

Bought a 1969 C20 last year. I have used info from this forum and youtube to do what little I have to repair and restore small items. I was having oil pressure problems and looked at posts here. ( I had done an oil change with full synthetic, thinking I was doing a good thing) Oil pressure dropped to almost zero after very little run time. And was virtually zero at stops on idle. Just changed the oil and went with Wix (Napa Gold) filter. Oil pressure back to normal. I guess from what I learned here the filter was clogged due to releasing all the years of build up in my 47 year old engine. Thanks to all
