A Fraction More Friction

Have you ever wondered how pink, orange, blue and green engine coolants differ from each other? Perhaps you’ve bought a car, checked the coolant/antifreeze reservoir for the first time and noticed it was different from your last car. The colour of engine coolant isn’t there to make it look pretty. There are historical reasons why it comes in

In a basic 4WD vehicle, power goes from the transmission to a transfer case where it is divided between the front and rear axles. In old school 4WDs, that’s all there was to it. It wasn’t a bad system, except for one big flaw. Because the transfer case sends equal power to every wheel, manoeuvring in a traditional 4WD could be difficult. For

The additional friction in the drivetrains of 4WD vehicles decreases fuel efficiency as well. In more modern vehicles, this difference is fairly minor – advanced synthetic lubricants in the transfer case and other components have gone a long way to minimising friction.
