It looks like a good trade off: A gain of several mpg in normal driving at the expense of having to add a quart of oil periodically.

A lighter oil, maybe letting the additive chemists have a go at it first might be the easy part of the fix. Getting Murricans to check critical fluids once in a while will be the hard part of the fix.

Once reformulated oil is developed and put in the pipeline, the recall would simply be a matter of getting folks in for a free oil change (make it a flush) and a pamphlet explaining the new oil specification. It'll be a bonanza, not a bankruptcy: how many maintenance items are going to get sold at the same time people are in for the "free oil upgrade?"
