Not bashing you here...
However, last year I did some compression & rebound speed tests with brand new XRAY adjustable piston shocks between XRAY 30/35wt and several AE and Trinity weight oils. Here are a few old posts with the results:
< == look at both of my posts on the page
I agree that Trinity seems to be thinner, but not by much when compared to how much thinner AE oil is to XRAY oil.
IMO from further testing over the last year with four piston holes open
XRAY 25wt = Trinity 40wt = AE 35wt (best guess for AE)
XRAY 30wt = Trinity 55wt = AE 50wt (all tested on shock tool)
XRAY 35wt = Trinity 80wt = AE 70wt (all tested on shock tool)
XRAY 40wt = Trinity 100wt = AE 90wt (best guess for AE)
Keep in mind also that the amount of holes open makes a big impact in the amount of change noticed for both rebound and compression between the oils. It seems that the difference between oils lessens as you use less piston holes. This is probably why people may see that AE 30wt is close to XRAY 30wt if they were to use say 2 hole pistons instead of 4.
The only way to be sure on what is changing, is to build identical shocks with differing oils (make sure they have the same # piston holes and amount of rebound). Then put them on a shock measuring tool and see if the needle stays in the middle on compression and rebound. You'll find that the difference in compression is slightly different than it is in rebound as well.
Thats why I luv the XRAY adjustable shocks. When changing oils, you can normally get close to what you want within a few clicks.
