Hello All, when I bought my '09 Sporty 1200 in June the dealer had already done the 5000 mile service. Seeing as how the hottest days of summer were ahead they put straight 50 weight oil in it. Now, seeing as how fall is almost here and temps are dropping into the 50's and 60's at nite, and no more 80's daytime, I would like to switch to 20W50. My owners manual recommends changing oil AND filter at 5000 mi. intervals. I've only put 1500 miles on it since June. Do you guys foresee any problems in just changing the oil and NOT the filter. FYI, I was a heavy-equipment mechanic for 22 yrs. and I think it'll be fine, BUT, this is my first H-D. Your thoughts? Regards, Low Sporty
