Re: Synthetic oil?

A friend of mine switched to synthetic oil for an old car, not a Packard, he had with disturbing results. Synthetic loosened all the sludge and other leavings from years & early use of non detergent oil - result. The junk cloged some crucial oil passages and led to catastrophic engine failure Or so he was told by the engine rebuilders.
I like synthetic oil - use in my modern drivers from new. But I'd only use it in my Packards after a rebuild.
