I was very tempted to switch from Mobile 1 v-twin 20/50 to mobile 1 synthetic 15w/50 but the more recent UOA/VOA show it has less additives then a few years ago. Not saying it is still not an option. However, it looks no different then other options where as before it stood out. Did I miss something? This is all new to me so please correct me, with some BITOG data of course ;), if this is incorrect.
