In my continuing preparations for my, (hopefully), trip out west, I've purchased a Twin-Air filter. Up till now I've used Ready Filter brand for the convenience and because I don't see a lot of dust on my home turf (Ready Filt. is kind of a thin element that's pre-gooed). But, I figured for out west I need a denser filter element. Anyway the thing is I don't really want to deal with the Twin Air Goo and goo cleaner on the road, I'm wondering if I could get away with just going old school and using dyno. oil, that I can wash out with soap and water.
