Thermosyphon warming process

[Dennis Nicholas]

Hi

I have noticed the gradual performance increase with time on the road, but always put it down to the slow warming and thinning of the gearbox and back axle oil, thereby reducing drag.

Early axles with the tar-like mixture of oil and grease must have had enormous drag compared with the teaspoon-full of 3-in-one used today.

And even more than if you use AFMT
