Anyone recently try VR1 FS 20w-50 in the V-twin engines? My Twin cam 88 and pretty much all Harleys have separate sumps so I don't care about wet clutch compliant oils. I can't find a VOA of this oil. Really interested in Oxidation values. I spoke to Valvoline TS and they noted several HD owners running it with good results. It probably has less detergents but I don't think its as low as some claim. I'd be riding 3-5k miles max a year. Currently running Amsoil V-Twin 20w-50 and their dedicated Primary and Transmission fluid. Have a few winter projects on the bike and decided to order some of this and a PG filter just try something different. Upgraded cam chest kit with bigger cams and upgraded oil pump. Thunder max ECU installed with O2 sensors, Really woke the bike up. Mostly Interested in max protection and cleanliness. I'm a fan of Amsoil and will probably switch back later. Amsoil Premium protection 20w-50 looks very similar to V-twin. Just have a slight doubt a constrained Jaso oil can protect as good as dedicated 20w-50.
