Castrol synthetic or Valvoline?

Hey Trailbeast,

Did you see the thread where there was a link to a very interesting oil test results site? It's called 540 RAT tech facts. A lot of reading but very worth it

From the link
"A Mechanical Engineer is clearly the most qualified Engineer to test motor oil that was formulated by Chemical Engineers, for wear protection capability between mechanical components under load."

I lol'd.
I think either petroleum engineers or R+D engineers would be far better equipped than an ME for analyzing engine wear.
