Hello everyone,
Submitted below for your review is the 6th UOA on my 2006 Toyota Tundra, with 4.7 liter V8 engine. In all 6 UOAs, I have included particle counts and TBN.
If you've been following my series of UOAs on this engine, you'll recall I've been using the particle counts to compare the Amsoil EaO filters with the Mobil 1 filters. In this latest UOA, I used yet another Mobil 1 M1-209 filter, which is an oversized version of the M1-102 that is normally recommended for this vehicle.
FYI - I had a VOA on this oil performed with particle counts and TBN which you can find here.
Here is the UOA, followed by my revised plans for future UOAs and filter comparisons.
Future plans:
In my last post in this series, I stated I would try different brands of filters for comparison. I apologize for this, but my plans have changed. Here's what I plan to do.
The currently installed filter, which will become the one used in UOA number 7, is a Mobil 1 M1-102. This is the recommended filter (NOT oversized) filter for this engine. I am doing this to see if there is any difference between the oversize filter (M1-209) and the recommended one (M1-102). Then, for the next interval, I plan to use the Amsoil EaO-57 (the recommended filter) instead of the oversized EaO-34. This will provide one final opportunity to see if the Amsoil EaO filter can equal or outperform the Mobil 1 filter for 5K UOA intervals.
This takes me to the 45K mile mark for this engine. Then, when I reach 45K miles, I plan to change the oil and cease using Mobil 1 5W-30 EP. I will then install Amsoil SSO 0W-30 for a 5K interval, which will take me to the 50K mile mark. Then, at 50K miles, I plan to change the oil, again using Amsoil SSO. But now, I plan to take change intervals to 10K miles. I will then repeat the ISO particle count tests, using the Amsoil EaO filters, and the Mobil 1 filters. This should hopefully address one concern with this study - that the short UOA length of 5K miles is "preventing" the Amsoil filter from showing its true performance. By doubling intervals to 10K miles, this should allow the Amsoil filter to shine a bit better.
The reason I am changing the oil to SSO - is for two reasons - I think stretching my change intervals with Mobil 1 EP to 10 K miles is stretching things a bit, given my UOA experience. I suspect the Amsoil SSO will hold up better, but we will see. Secondly, this whole thing about Mobil 1 not passing SM performance levels is bothering me, and I am in the mood for a change. This is a big step for me since I have been using Mobil 1 now for 32 years!
