Travis good you brought it up, now there is a
voa out there and prior we had none, great moly! Looks stouter then redline on paper except for operating visc.
I sent off for this VOA because of the disappointing analysis I got a few weeks ago.
MPT UOA The fine folks at MPT sent me some replacement oil to try it again at a lesser interval, they believe the UOA was affected by some type of fuel additive (I don't think I even used any). I still don't see how the TBN would be so low. Blackstone Comments: Thanks for the notes. We found some lead in this sample, so we ran it twice and it was still there, so that could account for a bit of what was found in your Sentra's sample. Silicon is an antifoaming additive and it's harmless in that form. There were some unusual additive levels in this oil. Note zinc. It read lower than phosphorus, while in most oils it's the other way around. We also found a lot of molybdenum (antiwear additive) and that could be why insolubles read high; it's probably just additive falling out of suspension. The TBN was strong at 11.5, since 1.0 is low.
