40 weight oil for VPI SAMA seems too heavy...

I use Shimano reel lubricant for my Michell TT with great results.

.
What EACTLY does VPI recommend? I recall decades ago they recommended a particular Mobil 1 but I don't recall the viscosity.

SAE 40 is okay for the spindle bearing but is too heavy for the tiny bearing of the SAMA. VPI recommended to me the use of sewing machine oil.

use lightweight machine oil or sewing machine oil

What's "SAMA"?

SAMA - Stand Alone Motor Assembly

Why don't you free your mind as to the correct stuff and get a bottle of it from VPI....you will know that it is correct.

Marakanetz - I have the Michell Gyro II, what exactly do you lubricate in the motor? Do you remove the top of the motor? how often does it need to be lubricated? I never heard of this before. Thanks

I do not lubricate motor.
I only lubricate spindle.

My GMC uses 5W30.

The Classic's manual clearly instructs the owner to use a 40-weight oil. Even though not SAMA, the bearing seems the same as on the motor of my old Scout. I used 40-W and it worked just fine, and it did not seem "too heavy." The only challenge was to apply it cleanly on the bearing through the tiny space between the spindle and the brass piece. Why would VPI recommend a maintenance product that does not work well with their product after all the years in the turntable business?
