Lamont - to be totally honest, that's my thoughts about particle counts in a nutshell. I am very doubtful of B/S counts.
THANKS FOR POSTING THAT!!
Doesn't mean Amsoil is any better.
Exactly! Especially if they're doing the counting.
Here's a test, hook up P1, M1, and the Amsoil filter side by side on a machine. Each filter is attached to its own base and has the exact same amount of oil and junk to filter. Run the test for 50 hours, remove filters and do a particle count? Refill the solution change the filters and run the test for say 100 hours. Is that how it's done?
I remember reading somewhere a quote by a respected member saying something to the effect of. If you run a test enough times you'll get the results you want. Made a lot of sense to me.
I often wondered why when Amsoil runs their 4 ball test they run the machine differently for ASM and SSO? I saw that question posed elsewhere as well. I'm not sure if it was answered I can't find it anymore.
SSO-Four-Ball Wear Test (ASTM D4172: 40kgf, 150°C, 1800 rpm, 1 hr) Scar diameter, mm 0.406
ASM-Four Ball Wear, 75°C, 1200 rpm, 40kg, 1 hour (ASTM D-4172B)
Always wondering and trying to learn more things automotive. I also read that 4 ball test is meaningless in determining how good an oil is, but that's another story. Thanks
