Some time ago I receive a note of how Amsoil was not being tested \against a real syntheic oil namely redline.Here is the note:
Hey, I looked at all the oils you have listed as comparison oils against Amsoil. Why not testing against a real synthetic oil ? I had a Amsoil dealer try to convince me to switch to his products until he tried Redline synthetic in a bearing load test. He showed how the Amsoil took so much more of a load to seize the bearings up than his comparison oils. He told me “You give me your favorite oil and I’ll show you how Amsoil will out perform it”. So I handed him a bottle of Redline 10W30 oil. After 15 minutes of trying to overload the bearings, he gave up because they wouldn’t seize with the Redline. All I’m saying is try your comparison testing against real synthetics instead of NASCAR day TV advertizing “Wonder Oils”.
PS -I fully concur with the reduced cost of synthetic extended drain intervals. I run Redline with 12 to 15 thousand mile drain intervals (ie. 1 year), with no ill effects other than having extra money to spend !
Well this test shows that Amsoil has tested aginst Redline
Another Amsoil deal had this posted on his site:synthetic-motor-oil-air-filters.com (thank you!)
Redline versus Amsoil.
Amsoil vs. Redline Oil
When AMSOIL created the Series 2000 20W-50 Racing Oil, it seems the competition got upset with the testing results showing it’s better protection. For years Redline advertised that they provided the best protection, but the results of the Four Ball Wear Test showed the AMSOIL Series 2000 20W-50 providing over twice the protection. Redline decided that they would perform their own test by running both oils and then seeing what results they would come up with. Their results some how showed their oil to be better. In an attempt to discourage the promotion of AMSOIL they mailed this information to all AMSOIL Dealers as well as their own reps.
While this is not a bearing load test there are many charts found on the net…
I will search later for more and post them here
