Is there any information on the coefficient of friction as it relates to 10w30 energy-conserving oil in general? For instance, some number or specification of an energy conserving oil that could be related to the JASO coefficient of friction test to draw a comparison. Or if an actual coefficient of friction test was done with an energy-conserving oil out of curiosity. BLS is saying what I've mentioned before and I think a lot of people have mentioned before. Energy conserving and friction modifier correlation have always assumed friction modifiers were secret pixie dust. If there was pixie dust, someone around here would have figured out what that pixie dust is. That's because pixiedust doesn't exist... To my mind the energy-conserving element simply is the lighter weight oil, which out of a sheer abundance of common sense, would lead to fractionally better efficiency.
