Viscosity question with Amsoil

[sarcher1]

Okay, I just got my blackstone on my 06 F250 6.0 running Amsoil Series 3000 5-30 with an Amsoil by-pass. Blackstone says that "the viscosity was low,but it wasn't due to any excess fuel dilution." What does this mean? The oil had 5000 miles on it when the sample was taken. The score that Blackstone rated it was 56.4. Should I have a concern? The previous report I had was using regular Motorcraft 10-40 and it had a score of 66.5 with the same amount of miles.

Can you post your Blackstone report in the used oil analysis please? Others will jump in when they look at the totality of the report!

Motorcraft 15w/40 ? 5w30 is a lower viscosity .On the opening page there is a link to the viscosity charts,study up! 56.4 is a 30wt.

Sorry, new to the site. Thank you LargeCarManX2. I will post now.
Steve S, I looked at the chart but for some reason, it is just not clicking with me. Sorry.

I looked up the Amsoils viscosity on the data sheet it is 11.4 The viscosity chart lists 30 wt as 9.50 to 12.49 cst at 100c your oil is borderline 30 /20 wt 15w/40 should be used.
