A few weeks ago the dealership sold me a Drag Specialties filter wrench and insisted it would fit. Its the kind you use with a ratchet, and it has a notch out to accommodate some fittings nearby. Today I was changing my oil in preparation for winter storage. I have a 2010 FLSTC. The filter is just too close to the engine block. The wrench *would* fit, but there's a small ridge around it and it will not seat squarely on the filter and it just slips off when I try to turn it. There must be a better wrench - any suggestions? Also, the oil (AMSoil) that I drained out and the filter only have about 800 miles on them. Is it ok to just put 2.5-3qts of oil in it and drive it in the spring with the existing filter?
