However, this means that an increased number of components operate under boundary lubrication conditions. This has led to a resurgence in interest in friction modifier additives, particularly OFMs. For example, recent tribology experiments [ 8 ] and molecular dynamics simulations [ 9 ] have given new insights into their behaviour under boundary ...

In both the interest of fuel economy and weight reduction, the B/C-platform ended the use of "big-block" V8 engines outside of the Cadillac division; after 1980, a 350 cubic-inch V8 was the largest engine fitted in a B-body chassis. In 1985, General Motors underwent a further downsizing of many of its nameplates using the B-platform chassis.
