ULSD increased PSI ?
Has anyone noticed an increase in LP fuel pressure with the advent of ULSD?

Staying away from it as long as possible... I buy 100 gallons at a time so I can shop around for 1200-1500 miles for what I want....

Yeah, only slight amount. Nothing to be worried about.

Yeah - I figured increased LP fuel pressure is a good thing, just like the ULSD mileage increase I experienced

The increased pressure makes sense since the new fuel has fewer aromatics, and thus logically higher viscosity. I'm just surprised that's it's measurable.

Mike your the only one I know that has actually got an increase in mileage. Mine has gone down .5-1mpg ever since I've been running this crud. Fuel pressure remains unchanged though.

By that logic, higher viscosity and less aromatics equals more power...
