--or is he making a play on words here
He states:
Speaking on oil consumption, Petkar observed that besides selecting low volatility base oil components, optimum viscosity also has a key role, as higher viscosity oils form thicker oil films, resulting in higher evaporation loss.

Briggs & Stratton condensed to the first letters of the two words in the marque's name.

Entirely dependent on the nature of the base oils in question ... Group I & II maybe (and I'm sure there is much of that in India ...).

Group II+, III and above, not very likely laugh

thanks Broc--wouldn't it be logical to think for 2 oils with the same NOACK, the higher viscosity oil/thicker film would lead to less evaporation loss?

Sure, as discussed many time over in HDEO forums, high viscosity oils almost always have lower NOACK and vapor losses. It's the 5 grade with a ton of VII's so it can make the 5W-30 rating that will boil off like blood in outer space laugh

Many, many trucking companies run 25,000 mile oil changes on big rigs with good old Grp II+ like Delo400 and get good UOA's. No excess thickening due to light hydrocarbon losses.

Many auto MFG's call for heavier oils when the cars are going to be tracked with the associated higher sustained heats. Even though they know that the fluid friction will go up and add to the heat load, they want film thickness. Mobil1 15W-50 anyone laugh
