You are assuming the "refiners" will honestly add said lubricants. that is the only worry I have.John_G said:1) Addatives are more easy to justify now. Nope. What the Author fails to mention, is that the refiners will be adding lubricity agents to the fuel during the refining process to off-set the loss of the sulpher's lubricity. So, we should see a net lubricity IMPROVEMENT.
