Hi,
Actually I am kind of impressed the two labs came as close as they did in the test results.
As far as wear metals they were almost spot on in perfect agreement, I mean, that is the purpose of the "test"
Yes, there is 10% variation in the test results on the additives between the two companies and certainly room for improvement, I would love to know which one was more accurate *L*
AS far as fuel, my only question would be what the OC thing is, are we comparing apples to apples?
Im also surprised the viscosity difference, to me, no excuse for the variation there, but what do I know?
Anyway, for me, I am relieved that the wear metals are as close as they are between the two labs.
Now why the 10% difference on the other stuff, eh, I dont know, just wish I knew which lab was more accurate.
