I was looking at them also and trying to determine which model is best. I contacted the Canadian seller here in Ottawa and he says "Your vehicle will take the F-108 valve and all variations, the regular F-108, F-108S, and F-108N" The only problem is which one or does it matter? Hopefully someone with experience can enlighten us. My Forester is only a couple of months old so haven't done any exploring under it yet.
thanks
These are the same valves that work on the 14-18 models, the 108 has no nipple, the 108s has a short nipple and there is a long nipple version. I would recommend the short nipple which has the leas impact on clearance. You'll want to have the 'nipple' as it allows you to attach a piece of plastic tubing which you route to your drain pan, thus eliminating the hazard of hot oil going where you don't expect or want it to go. Having at least warm oil allows it to drain faster and more thoroughly.
My procedure is:
1. Plug one end of the plastic tube into my catch pan with the nipple adaptor on the other end.
2. Shimmy under the car (no jacks required) use a Philips head screw driver to remove the plastic plug bolts from the oil drain cover, attach the nipple adapter to the fumoto valve.
3. Remove the plastic safety clip (prevent unintended opening of the valve), open valve, drink beer while letting oil drain and removing old filter.
4. Reverse above procedures, use oil residue on gloves to lube new filter o-ring and install new filter.
5. Add requisite oil type to manual specified volume.
Whole oil change takes 15 minutes but I usually rotate and inspect the tires, inspect the suspension and cv boots, and grease hinges while I am doing it so 40 minutes all in. Saves money and time at the dealer and gives piece of mind that you gave everything a once over.
