note that on an older engine, fully synthetic oils may cause oil to leak out because of old oil seals and gaskets.... manipis ang FS oil, so pag luma na ang oil seals, pwedeng tumagos sa mga seals.
if you are using mineral oil right now and you are not having problems with it, don't fix what is not broken.
