Blackstone's comments: Wear still looks excellent....Fuel dilution was still present at 1.0%.....not high enough to indicate a problem, but we are a little concerned with its continued presence.....fuel has lowered the viscosity a bit.

Comments please.

How many miles on the Penn?

 

[Smitty]

Sorry, 4,500 for the Pennzoil.

Did you have air filtration problems while running the Pennzoil?

 

[Smitty]

Green Max, I don't know. I changed the air filter after about 1yr. just after the penns uoa.

The analysis are pretty close considering the amount of silicon and the more miles with the Penzoil. So actually your silicon is less than 8 and the iron less than 26. The fuel dilution is the main problem but it's below the level that requires corrective action (3% -the source I have)

Both are thin as water ..........

I just got an update from Blackstone because they left out the TBN. It was 2.7
