AMSOIL's comparative testing

I don't know.....take for granted that GTX is the biggest market share for Castrol, for which Amsoil is after, but is Synpower Valveline's largest selling product? Is PP Pennzoil's largest? Amsoil did not say on what principle the competing oils were selected.
As an Amsoil guy, I would like to see them test ALL the off the shelf Dino/Syns in all the viscosity's available versus their own product instead of just selecting a few.
Not that I don't trust them... No doubt they are exceptional, but by how much versus the competition would be nice to know!
The tests are expensive to conduct so they can't test every oil out there. I am always amazed, however, at how there is no public refutation of the results by any of their competitors. I don't care WHO pays for this type of testing when it's placed all over the world and no one says anything it must be pretty close to accurate benchmarking for the selected variables tested. The TFOUT test is a total crock though due to the base oils being different and those results should be removed.

The test were done by SW Research.
SWRI is an awesome outfit. They are costly, but do great work.

Only comment that I have to add is that I'm assuming there was more than n=1 samples per brand pulled for testing. If not then I would totally discredit the results. If the bar charts don't represent a mean that would not be good!!

This info coming from Amzoil, instead of an advertising claim from Valvoline itself makes it very believable. Synpower looks like really, really good stuff.
Most of Amsoils tests and literature are geared for people who do not know about what they are reading.
Short bar is better than tall bar.....I learned that in grad school once when I was looking at my 4 balls prior to a wear test.
Test my product so it looks better. I am not knocking Amsoil . I can get my vehicles to outlast my ownership by far using any proper speced dino oil. I have used syn oils before syn oils were thought of to be the best and at the time they may have been but todays dino oils are great.[unless syn is required]
