any truth to this

If you wish it to be so and drive smoothly enough to make it so, then yes.

I used to work with someone who had a readily available supply of mineral insulating oil, and their diesel ran fine on it...

No-one claimed it wouldnt run on it :)

thin oil usually will show a mpg improvement, look at fords e oil, it even says so on the can.

Also note that the above site is by an official redneck from a trailer park with a pick up truck, so the improvement might even be caused by ufo's.

Agreed. But adding about 3% to the crankcase oil for a 30% improvement in fuel economy? Without very creative driving, I think not.

As I understand it, even the industry standard ACEA B4 for improved economy engine oils only claims something in the order of 1.3% improvement.

He's added some to the fuel as well, but no upper cylinder lubricant that I'm aware of makes a measurable improvement to economy.
