I was picking up a bunch of Royal Purple and Edge I bought online
using the 40buck discount code.
The young man that rang me up asked how long I run my oil. I
told him and he then recommended I send an analysis to Stavely
Labs ( to know how much longer I can run it.) I told him I
familiar with Blackstone but have never used it. He then said
they are a good lab but affiliated with BP and possibly
biased. He then said his favorite oil is Valvoline Synpower
because it has the most zinc allowed by the EPA and that
benefits the engine he has. I may or may not agree with him but
admired his interest and knowledge.
