Well, I finished my first oil change on my 2006 FLHTi all by myself. Pretty proud of myself I must say. I was a little intimidated by it but pulled it off with no problem. I went with Mobil 1 V-Twin in the engine, Mobil 1 75-90 in tranny, and HD Fomula+ in Primary. Thank you guys for helping build up my confidence to do it myself and save myself at least $100 by not letting the stealer do it. One question, what thread sealant do you all use on you drain plugs if any? Thanks
