Decided to compare the 3.8 stock filter to the larger "truck" filter that is the common upgrade, to the standard remote mount filter.

Stock filter is 0.37 quart
Truck filter is 0.54 quart
Remote filter is 1.17 quart.

These volumes are based solely on the exterior dimensions of the filters. They are actually less due to rounded ends and oil displaced by the filter medium, valves, etc inside the filter.

The 3.8 oil capacity is listed as 4.5 quarts. By adding a dual remote filter using two quart filters, the oil capacity is increased to 6.13 quarts over the stock filter, plus a little extra for the housing and hoses.

Although this is not oil in the pan, it is oil circulating in the system, which has the following advantages (this I have condensed/summarized from various articles):

1) The oil spends less time in the engine, and therefore is a little cooler.
2) Contaminants that are not filtered out, are more dilute in the increased capacity.
3) Oil does not break down as fast.
4) The dual filters hold more contaminants.
5) Dual filters do not clog and open the bypass valve as soon as the stock filter.
6) Dual filters have more square inches of filter media, providing less restriction by filter media on the flow of oil.

This is why I'm installing a remote dual filter kit. Trying to figure out where to mount a remote dual filter kit, and mount it vertically, not horizontally as is common with dual filter kits in F-bodies.

I'll post some pics as the project progresses.
