Also more expensive oil does not equal better oil.
That signature series runs $11.50 a quart. Regular amsoil syn is only $7.50.
I run 10w30 in the van, 5w30 in my built motor. Never had an issue or a reason to do otherwise.

0w-30 only makes sense in extremely cold weather, else it has too little viscosity on cold-starts and gives results like these.
I think there are actually budget 0w-30 offerings on shelves.

0W-20 is what I used in the place of the factory recommended 5W-30. I did it two years back-to-back with no issues, Spring/Fall/Summer/Winter, supported by Used Oil Analysis.
Basically, when folks said that if a 5W-20 or 0W-20 was used in an engine that was originally specified for a 5W-30 or 10W-30, the results would be disastrous, e.g. the engine would blow-up, the radio would stop working, the wife would leave me, the first born child would die, etc, etc. None of it. The engine was protected fine with no harm done.
With these preliminary results, in this application, I believe I could run a name brand motor oil in any of the following grades: 0W-20, 5W-20, 5W-30 or 10W-30, and engine wear would be equal across the board, no problems, supported by Used Oil Analysis as I've demonstrated here.

Example given:
At 5 months/2665 miles, the 5W-30 had 7ppm Iron, 1 ppm Aluminum and 1 ppm Copper
At 11 months/5,194 miles, the 0W-20 had 19ppm Iron, 5ppm Aluminum and 3ppm Copper
Had the 0W-20 been sampled at the same 5 month/2665 mile interval, I believe it’s safe to assume there would be no meaningful difference in engine wear when compared to the 5W-30 at the same interval.
Also consider how we are talking about parts-per-million (PPM), so a very, very, small almost non-existent amount of wear particulate.

The myth that Pennzoil causes engine sludge comes from a half truth that dates back to the 1920s and 30s when Pennzoil was pumped from within the earth from the state of Pennsylvania at a time when hydro-processing and additive technology was either in its infancy or non-existent. The same was said about Quaker State. Today, name brand modern motor oils cannot on their own "cause" engine sludge to occur. If sludge occurs, it's from an environmental factor.
The wear is accumulative. Note how the 0W-20 was run twice as long as the 5W-30.
The wear is accumulative. Note how the 0W-20 was run twice as long as the 5W-30.
The wear is accumulative, but the 0W-20 also had more the twice the ppms, so regardless of how minuscule the wear may be, it's still wearing more. Any difference in wear is meaningful. It may be the difference in making 200k or making 500k. I prefer my vehicles to last.
