Scootr knew his motor oil for sure. I communicate with him rarely but it has been over a year since I heard from him.
Ok my memory is not worth spit but if I'm not mistaken Skootr, tested fuel and oil but not necessarily strictly related to diesels. He was however working on a white paper related to new lubricants required by the new stringent emission standards. If I'm mistaken I apologize.
One other point --- BTW I'm in awe of the motor oil experts on here but have one question.
Someone maybe BR mentioned that diesel engine oil was not the way to go since diesel engines had such low revs. I am of the notion that diesel engines have tons of torque and could require lubricants equal to any application.
