Where does it say that? I must have missed it.....


In the last two updates, and i was wrong it's 5-40 not 10-40:

A road trip caused us to miss our sample by a hair over 100 miles. At this point the oil looks black, like used oil ought to. It also continues to thicken up, and is now officially a 5W40 oil instead of the 5W30 we poured in there. Frankly, this annoys the heck out of us -- if we wanted a 40 weight oil in there, we would have bought a 40 weight oil -- and we would have quit right here, except it's not worth the din of hate mail we'd get. So, we'll see what happens, particularly whether TBN manages to rally, 'cause at the moment it's dropping like an acid eater. Wear, however, continues to be for all practical purposes inconsequential. A good oil, yes, but a long-termer? We'll see.

Finally, it took a while, but here we are at another sample. Not much new to report. Everything's stable at the moment, except for TBN, which continues its spiral downward. The laboratory says 1.9 is still good, but if it doesn't level off soon, then Amsoil will be done in 2000 miles -- even allowing for the 40-weight viscosity. Interesting that Amsoil seems to not display the TBN boost from make-up oil that Mobil 1 exhibited -- or if it is exhibiting the boost, then God help anyone whose engine doesn't use oil! No easy way to know, really, without complicated tests on multiple engines.
