a lot of bull on the polaris oils. they show no specs or details because they know its [censored]. the original owner had the 500 service done at the stealers, since i bought it no polaris oil in it. my vic was consuming a bit when i got it at 833 miles but a good spanking + better oil cured that, change yearly + never add between. i have 3 bikes so miles are not that high. currently on Silkolene Pro 4 motorcycle oil 15-50, a group III with ester, its working well but poor weather is limiting riding
