This prof figured 30% would be about absolute max. My understand that present car engines are at least 35% max, maybe a point or so higher, even. 'course, I have heard that industrial diesels are in the high

That figure for car engines is best efficiency, at optimum load and rpm. Average over a real urban driving cycle is of course much less.

At one time didn't PM run advertisements for some of these fuel extenders and other miracle products?

That is a useful article, although for most of us it proves the obvious. I only hope the crowd that would be taken in by such snake oil pitches would also read PM.

PM ran a bunch of snakeoil ads of all types. I noticed that in this issue the classified ad section in the back of the magazine was very very small.

I hope this is a trend toward a quality magazine, since the recent years of both Popular Science and Popular Mechanics have been worthless.

I cannot understand why no one has filed suit against these people, since it is clear they are bilking the public, the products are worthless, and the claims are false.

I dont mean PM or PS. I mean the purveyors of worthless mileage gadgets. Sorry for the change in the line of thought.
