: If you don't have leaking gaskets now, you won't have them with a better oil.. synthetic is an engineered oil not voodoo!

TO quote the maker of one of the highest
quality synethic oils there is:

"Royal Purple will not cause an oil leak. In some instances, usually in older engines that have not been properly maintained, there may be a bad seal or cracked gasket that is not leaking because
it is filled with oil sludge, lacquer and varnish deposits. Synthetic oils are designed to carry away deposits, so it is possible to expose marginal seals after those pre-existing deposits are removed. If an engine leaks after putting Royal Purple or any other synthetic in, the oil is probably not causing the leak, it is
exposing an existing leak. In these cases or in older cars where this might be a concern, it may be best not to recommend a very lightweight oil. In the long run, it is better to replace a faulty
gasket than to leave those deposits in the engine."
