So im doing a full service on my 06 k9, I went down to autozone and got royal purple 20-50 motor oil and got the 75-145 gear oil. I dont know much about this cause this is my first service on my bike. The S&S tec told me royal purple was the best over moble 1, and was quite a bit more price wise. Also does anyone have a part number for the oil filter? Thanks for any imput...
