Nick,
Thanks for posting the PS VOA! I'm currently running 4oz of the PS Oil extender in my 04 Impala's 3.4L with M1-5w30. I did a UOA on the oil change before (w/o PS). I'll do another UOA on the next change with the PS extender and post results. Before deciding to try it I requested the MSDS from PS and judging from the MSDS it looked like the extender might be a way to enhance the additive pack including ZDP. I also sent them an email asking if the extender contained any VI improvers. Here is their reply...
"Diesel Lube Oil Extender does not contain any thickeners to affect the
Viscosity Improvers of the oil. It will not affect the base of the oil
either. It only affects the detergent package of the oil. This is why
our product will not void engine warranties. It does an excellent job of
dispersing the soot in the oil which reduces sludge formations. It will
stabilize engine oil, reduce foaming, oxidation and help neutralize
acids.
I have attached a spread sheet showing all the tests that it has passed.
I don't know of another oil additive that has been put through these
strenuous tests and passed. Most oil additives will thicken the oil.
(Summary from the spreadsheet:
Tests: Caterpillar 1K Test, Detroit Diesel 6V92TA Test, Mack T-8 Test, GM 6.2L Test, Mack T-6 Test, Caterpillar 1N Test.
DL Oil Extender contains zinc which helps fill in or causes a molecular film to form over the cracks and imperfections of the combustion chamber (lower cylinder wall) which prevents cylinder from using oil. DL Oil Extender contains magnesium which is an excellent lube agent)
If you have any other questions or concerns please give me a call.
