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.

Thanks Dennis 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.
