Why do some MOTOR OIL brands not publish some ASTM testing results?

If there is a test that says “Not Listed” it’s because the oil brand does not provide those test numbers to the consumer on their website.

If their test numbers are good, why don’t they share them with us?

We all know that when you’re proud of your test result whether it be a test in school or an ASTM Oil test the first thing you want to do is share your accomplishment with others.

Perhaps they know their test numbers are not as good as their competition, so they don’t publish it, because that would imply their product isn’t as good as the competition.

Would you trust a product from a company that holds back its test results?

After looking at many oil brands I was surprised by the lack of transparency with ASTM tests.

I would only deal with a brand that is honest and proud enough to show ALL their test results because it shows you that they have integrity, passion, and nothing absolutely to hide!

AMSOIL is a company that has a reputation for being honest, sincere and displays strong integrity to provide the absolute best for their customers. AMSOIL knows that their customers appreciate their longstanding devotion to making the world’s best synthetic motor oil and lubricants that blow the doors off the highest industry standards.

Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and followed the AMSOIL lead with introductions of synthetic motor oils of their own. Accept no substitutes.
