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

I used a much lighter oil expressly for small electrical motors with an extension wand which made it very easy to lubricate the SAMA motor for my Super Scoutmaster. this eliminated noise and vibration which recently affected the motor. The 40 weight automotive oil recommended by VPI is for car engines and I think it's way too heavy for small motors like VPI/ What are your thoughts on this?

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.
