I didn't look up any Valvoline uoa's to see if the additive packs where comparable like some there were saying.
Also, the viscosity should be robust enough to handle some fuel dilution.
I have an unopened bottle of the Supertech hm 10w40 so might be sending in a vos of that oil and then a sample of the used oil in my engine since I just got my kit from Blackstone in the mail.
