Toilet Paper...

[Power Wagon]

Many moons ago, when I was a little kid just outa diapers, my dad used to sell Motorguard oil filters. They used a roll of two-ply TP as the filter element. I have no idea what they did for micron size, but they would remove quite a bit of water and hold it, and in tests on 60's diesel engines, they would keep the oil looking like it came out of the can.. It would not get black.

Dad ran one on our car for years... and it would do just that. The oil looked the same color after tens of thousands of miles as it did the say you put it in. I have to admit, that old Plymouth went a heck of a lotta miles with almost no wear, too. After almost 300K on the engine, it's still standard bearings.

I could swear that SAE or someone did testing on the filtering capacity and determined it filtered better than almost anything else on earth... but hey, wouldn't the company selling it put it's best face on things?

Just thought I'd probe the brains of your old-timers and see what you thought of them...
