Amsoil Oiling System - Fantastic Filtration

Amsoil's remote filter kit comes with everything you need to adapt your engine to the black gold. A black billet filter-mount assembly holds both the oil filter and a bypass filter, while 13/32-inch high-pressure hoses with NPT hose fittings send oil back and forth between the filter adapter that screws onto your engine in the original oil filter's place.

Standard oiling systems are fine for most vehicles, but for hard-core-use 4x4s with hi-po engines, you should really be looking at some type of remote-mount oil filtration system that adds oil capacityand longer-lasting, better filtration for your engine. Improved filtration and oil capacity improves engine life and in many cases allows for longer intervals between oil changes.

Last time we drove our Dodge (it has been some time, no jokes, please) it was blackening oil in less than 2,000 miles. It was now sitting at the Dyno Shop in Santee, California, to get some engine calibration done to make this truck run a little more smoothly. But even with the engine running right, this truck was still going to get flogged off road and something had to be done to improve the oil system. We wanted a remote mount kit with two oil filters that'd keep our engine a little happier, and Amsoil's remote filtration system was just what the Dyno Shop prescribed.

Amsoil's bypass-filter assembly has an incorporated spring-loaded check valve built into it. It basically directs 10-15 percent of the oil flow into the bypass filter, allowing the rest to go through the primary oil filter. Why do this? The bypass oil filter filters down to a much smaller micron size, letting the dual-filter assembly accomplish a far superior filtration job over a standard single-filter setup.

Amsoil provides one long 13/32-inch high-pressure hose that you should cut into two equal lengths to send oil back and forth from the engine to the filters. When you get your hose cut, unscrew the hose fittings and screw the socket onto the hose in a counterclockwise motion. Once the hose has bottomed out in the socket, put a little oil on the hose fitting nipple (to get it into the hose more easily) and start screwing it into the socket as demonstrated by Dyno Shop technician Shawna Macneil.

We drained the oil and removed the original oil filter on our Dodge to replace it with this adapter casting. The adapter comes with four color-coded thread adapters to get onto your engine. The kit also provides a larger O-ring casting for the adapter to accommodate different OE filter sizes. Two provided 3/8 NPT to 1/2 JIC adapter fittings are used to join the high-pressure hoses to the filter adapter casting.

Amsoil recommends mounting the oil filters as closely to the original location on the engine as possible. We would've liked to mount the filters on the frame, but due to space limitations we had to stuff ours on the inner fenderwell. When mounting the filter assembly, the acceptable angle range is from vertical (hanging the filters straight down) to 70 degrees. Never come closer than 20 degrees to laying the filters horizontally.

Once we had the brackets on the fenderwell, we attached the high-pressure hoses using the supplied O-ring fitting adapters. There are arrows on the assembly's inlet and outlet pointing out the direction of flow and labels on the adapter casting as well, so you'd have to be almost brain-dead to screw this part up. Now that we said this, we know at least two of you out there are going to have problems....

Of course, we poured some 100 percent synthetic Amsoil into the engine once we had everything buttoned up (don't forget the drain plug). Our engine took a couple extra quarts with the Amsoil remote filter kit, thusly adding extra cost to every oil change, but also adding longer intervals between each change. We definitely notice a difference when using high-quality fully synthetic oils, though we have to admit that we have had equally good luck with most high-quality synthetics.
