planning on making the change back to 10w-30 oil in my 2166, does anyone think it will hurt anything to just reuse the oil filter with the new weight oil since it's only about 20 hrs old? The manual says I can go 50 hrs on the filter before I have to change it again. No big deal to get a new filter, but I also wondered what the cross reference was for this filter so I can just go get a wix or equivalent filter instead of having to run to the CC dealer for one every time.
