Hello again everyone,
Here are the results of UOA number 8 on my 2006 Toyota Tundra Limited Double-Cab 4WD. This was another 5K mile interval, using Mobil 1 EP 5W-30, and the recommended Amsoil EaO-57 filter. This is the best showing of the Amsoil EaO filter so far, roughly equivalent, however, to the worst showing of the Mobil 1 filters.
I changed the oil after this sample was taken, and have installed an Amsoil EaO-34 filter, and intend to run this batch for 10K miles. Blackstone seems to think it is doable (See the comments section). I will then post a UOA (with particle counts, of course) on this upcoming interval.
Then, I intend to perform a second 10K run using the Mobil 1 filter. The reason for this is to see if the extended interval will improve the filter performance of the EaO filters relative to the Mobil 1 filters.
Of course, it will take me longer to run 10K miles, so you probably won't see another UOA from me until around the September/October timeframe.
Comments? I think it is very clear at this point that the Mobil 1 filters perform better over such a short interval, at least as far as filter performance goes.
