Review: I like the packaging - Excellent product
Review: Runs cool, well kinda, in Kubota BX2230 - After 20 years I decided to convert my Kubota BX2230 to synthetic oil since everything I've read indicates synthetic is superior in every way. I wish I could say that the tractor now purrs like a kitten at idol but that would not be honest. it still rattles and shakes like a 1960's rock and roll gogo girl. But, that's okay. As long as it keeps running I will be happy.
