Air cleaner oil

A non detergent oil is recommended for the air cleaner. This stops dirt particles being held in suspension on the wire mesh and drop into the bath below. With this in mind instead of trying to buy non detergent engineoil,I was thinking of using a vegetable oil. Any thoughts?

Not important cheapy oil as below
Just catches dust and turns to sludge

Any old cheap oil will do

None detergent oil is also recommended for the engine. Not that it stops people using modern stuff.

Non detergent oils are essential in engines without engine oil filters, such as the early Side Valve Fords, and I know these oils aren't easily found these days.
Detergent oils have lots of additives which are designed to pick up sludge, carbonised grit, etc, and hold it in suspension until it reaches the Oil Filter.
I would not use a non detergent oil in a diesel engine as the greater carbon deposits would fall out of suspension and build in the sump.
They recommend for oil bath air cleaners the same viscosity oil as in the engine crankcase.. but non-detergent, so dust isn't held in suspension and will fall back down into the pan at the bottom, where it settles out and forms a layer of crud in the oil bowl.
Using a detergent oil will hold onto the dust and not allow a layer to form in the bottom bowl. I've always used standard engine oil but having seen this I was just considering a trial using Veg oil.

I have been using modern engine oil for well over 10 years now, dont forget air does not actually pass through the oil in the filter.
