OK just a correction here....the tank "filter" should be called a strainer as it is definitely not a filter although called that, it is a misnomer. As said here earlier "it will allow minute (and not so minute) solids of various description to pass through and continue to wear out items in the engine. Why have the military of many countries insisted on a good quality filter which is either of the felt type (M20) or paper (B40) to be fitted in the return line of their machines? Because the strainer in the tank does just about bugger all in the way of stopping foreign bodies from circulating in the oil. The British Army B40 had a British Filters paper element fitted in the return line of all their bikes yet BSA still didn't fit one as standard on any civilian bikes. Cost saving I imagine. I made sure I fitted one to the Ceefer before even starting it after the rebuild. Now I'll get off my soap box. Cheers. Gerry

Yes they really are clever .
Multigrades use detergent addatives that are homophobic so after they totally envelope the impurity paticale they prevent any further agglomeration so the now quite big envelope of addatives with crud in the middle can not pass through the filter medium

Monograde's detergent addatives are homephillic so after they envelope the crud they join together at infinitum to form a big lump of crud which sinks to the bottom of the oil tank to form a sludge.

That's literally incredibly educational.

Would washing soda work just as well?

I was once shown the molecular formula for some of these by Gerry Bristow who uses to work for BP then Duckhams, Brilliant bloke, died way too young.
Very simple when you see how it works but how the molecules stay together is beyound me.
Some had open bond at one or both ends while the others had them at one end & in the middle so when aligned will bond together.
