As an owner operator of my own truck, it's nice to have that extra edge. I pull sea containers in and out of the Jacksonville port and I do a lot of overweight 80,000lbs plus. The filter is in a 1998 Freightliner Century Class with a Cummings 500 HP with a 10 speed transmission and a flow through exhaust. I run only in the southeast there are only some hills and my fuel average is 6.7 to 7.2 running 65mph at 2,500 rmp.

Awesome filter. Lasts 10 times longer than standard filters. It's cost vs standard pays for itself several times over.
