I changed mine to Neo which I read in a mag that the Subaru rally team uses. I like it. The funnel is very important. I have one I picked up in the OIL change section of my local autoparts store for about $5. It allows me to measure in ounces, ml, quart. It has a flexible hose and ON/OFF valve which works very good for putting oil in a Subaru tranny. If you go too fast on the tranny you end up with expensive oil down the side of the tranny and all over the floor. With this cool funnel you just turn off the flow and wait a few seconds for air to escape then turn it back on. When your done you have the exact amount of oil in. For clean up just spray some brake cleaner in the funnel & wipe with paper towel.
