viscosity - Mike Williams
I have been looking at various oils recently and have seen some quoting very wide viscosity ranges, for example SAE 10w-60. However what really interests me is the odd one that claims, SAE 0-40. How can this be? How can there be an oil that can possibly claim to be frictionless, or am I missing something?

Any help welcomed ....... Mike

This is a brilliant site to find anything about oil,additives and viscosity.
However I just checked and it says this site is down for the next hour.

The internet is suffering from high viscosity at the moment... ;-)

Zero viscosity doesn't mean zero friction, it's the thickness of the oil at cold and working temperatures they are talking about. It's true that you can't get a true zero viscosity oil though, but if you have a look at the other link suggested here, you will see how they calculate a zero viscosity. Please don't think that a different viscosity will necessarily make any difference to the running of your engine, you should stick to what the car manufacturers recommend, especially on older engines.
