    what do you think? local shop dis-likes synthetic oils,says engine rattles too much for his taste, so he uses spectro 20x60. i on the other hand i have used synthetic since i bought a '74 fxe new and all vehicles i have run synthetic.
    Have any of the bulders comprared a well maintained h-d engine that used
    any of the aftermarket v-twin oils comapred to a h-d engine using full synthetic Probably under racing conditions? is where you would notice any differences (IMOP)?
