My local Wal-marts just started carrying Valvoline Full Synthetic motorcycle oil (4T stroke) in 10w-40 and 20w-50. I've never seen this stuff before. Is it something new from Valvoline? I don't see it on their website. The two Walmarts I shop at used to only carry Castrol Full Synthetic MC oil but then don't anymore. Now it is only the M1 v-twin and the Valvoline. They also now carry the Valvoline MC conventional oil too in both 10w40 and 20w50. The M1 is $8.97 and the Valvoline is $7.97. The Valvoline conventional is about half that.
