Relatively small clearance...will try to dig something up.

The viscometers I bought for my condition monitoring guy back in the day were test tube bubble viscometers.

Test tube filled to line, then inverted...bubble formed, and had to "fight" it's way to the top, with the film of lubricant running between the bubble and the tube.

They are an ASTM set in and of themselves.


I used to use these back in the day. These would do what you wanted.

At -40F there most likely will be a difference between group3 and group4/5. But my garage is heated in my house and it really rarely gets down to even -20F around here. A $3 a quart synthetic for 7-8k interval will be more than good for me.

Since I have some M1 HM 10w40 and EDGE HM 10w40 maybe I’ll do a cold pour comparison soon. It’s like 25F here today and wasn’t bad this a.m.

At 25F you will not see any difference.

I was talking about maybe later in week or Saturday when it will be -9F they say
