Yamaha study on bearing lubricity with 2 stroke oil. pdf

So, ............................ how much of that did you read? Understand?

Your thoughts?

Rather deep reading, I kinda skimmed over it. One thing that jumped out is the lack of "Brand" names of tested oils :mad: Think they would have at least shown where Yamalube was on charts.
 
Kinda just skimmed through it myself. I think I might have to read this one 2 or 3 times to get a more better understanding. One thing I thought was cool was how they had a temp sensor on the big end bearing.

My conclusion; Polish your exhaust port to as close a mirror finish as possible ;).. and use mineral oil (?).. "It has been reported that polybutene based oil causes a slight drop in engine power output compared to mineral based oil."
