Verified Customer Reviews for Millers Oils ZFS 4T 5w40
I'm not exactly an Oil exploration expert.....

This fully synthetic oil from Millers Oils appears to me to be pretty much as good as other, far more expensive synthetic oils and being a 5w 40 it certainly gets to the top end of my rattly old Fireblade quicker from a cold start than the previous oil did, so that's a good thing in my book.
Helpful?
