Ford Unveils Mercon LV

key word here is "can have," doesn't mean that they do. Perhaps some do, but my guess is that most heavier weight oils will have the thicker oil film - and I repeat, that's my "guess."

The problem is that the majority of people just can't get their head around that.

Can we have a tutorial as this is something that has not been brought up around here much but is most interesting.

That is true - low visocity fluid "can" have higher fluid film thickness than high viscosity fluids.

I think the reason there is a "can" in the above statement and previous post is because a lot depends on what additive package you have in the low viscosity fluid too. Its not always about finished fluid viscosity. I am in no mean saying that baseoil viscosity does not matter - but you have to look at the complete product and not just one aspect.

""higher fluid film thickness"'

you mean higher fluid film strength

film thickenss is mostly due to viscosity
film strength is a combination of additives and viscosity

Whitewolf pointed out to me that film thickness is NOT all the time due to viscosity alone I stand corrected.

You are too honest for your own good Bruce.
