So, here is my second run on Amsoil 0w-30, this one with the 'new' AZO formulation. This is the first OCI with Lubro Moly MoS2 sampled in this app; it appears the use of slightly more than half the can(as per the instructions of correct add ratio on the can) increased the ppm about 100 or so. Capacity: 3.5 Quarts Oil filter used: Amsoil EaO20 Air filter used: K&N drop-in replacement http://img249.imageshack.us/img249/5550/uoa3.png
My previous concerns were insols and it seems the use of Amsoil's EaO filter helped in that area at least. I have an ongoing interest in Si levels, but since I had to remove/reinstall the Oil Pressure Switch twice, each time with fresh Ultra Grey; which has silicone in it's composition, makes that a wash in this sample. So, for now I'm still using a K&N air filter drop-in replacement. The concern for pulling this sample was regarding other issues with this app(not necessarily the engine itself). Those are related but not limited to: the clutch being worn, prematurely fouling of spark plugs(though not inoperable or causing misfire), and an oil pressure light condition(well, sort of, long story). Overall, the driving habbits in this car have had to change because of the clutch issues and also now what appears to be a failing master cylinder at the clutch pedal itself. Fun stuff, for sure. Long story short, I'm needing to find what the hot idle oil pressure is vs cold. I'll need to get a gauge and see how things are reading compared to factory specs. Still running the same fill in this sample until I decide to change it out. Now installed is a PureONE PL14459. There was concern over the EaO starting to load up, it could be all in my mind though, but an oil pressure light condition can scare you out of your wits. I do plan on cutting the filter open. No more Amsoil left over for top-off so I'll need to change it in about another 1,500 miles or so at the current rate of oil consumption/loss.
