.... body pick up with over 400,000 miles on it because of that stuff. It is in every gas powered item I own. Amsoil is the best IMO. You should see the insides of an amsoil engine, so clean, with no "gunk" anywheres to be found. I can go on and on about it.

I change my amsoil when it discolors. With their fiter, that takes a while...

In OTR diesels (18-wheelers), Mobil recommends 100k miles change intervals with Delvac 1, and engine rebuilds at one million miles. These motors all run with ultra-fine bypass filters, though, which is a large 2nd oil filter in parallel with the normal filter. I once saw an oil test were the oil came out of the motor with less particulates than new oil in the bottle.

AMSOIL Super Duty Oil Filters (SDF) are designed for maximum efficiency, capacity and longevity, while meeting the high flow demands of modern engine designs. In fact, with its advanced filtration media composed of a special Cellulose, Synthetic and Glass Blend, AMSOIL SDF Oil Filters have over a 75 percent better combined efficiency/capacity rating than other popular oil filters as tested according to industry standards. AMSOIL SDF Filters are also approximately 65 percent efficient at removing 10 micron particles. In addition, AMSOIL SDF Filters are designed for extended drain intervals of 12,500 miles or six months (whichever comes first), making them ideal for use in conjunction with premium AMSOIL Synthetic Motor Oils.
