Silkolene Pro 4 Engine Oil 4.5 5 2 2
No Complaints Great product! Works as directed and advertised. Engine runs better than new. No complaints here. October 20, 2014
It's red! My motor is still working after using this oil. Not once did it seize up or knock. I'm very happy about that aspect. Also it's red! I feel like I'm cooler than my friends cause I have red oil. On a serious note I did notice that my 2013 zx10r on the interstate on a cold day would stay at 151 degrees with motul 5100 oil I had in it. Now with silkolene it stays at 149 degrees under the same conditions. Maybe it's helping my engine be more efficient with less friction. Maybe it's voodoo. Nobody really knows, but we can all agree the voodoo would be more exciting. December 23, 2013
