I'm not that person and I've used the 30W non det since my first CL72 (1963) and still use it in my 1963 CB77 today. Never a dirty, sticky inside of the engine and it's not expensive. My opinion is the filter removes the filth better with ND than with Det. Consider this please. WHEN WAS THE LAST TIME YA SAW HONDA SELLING 30W NON DET!!!!!!!!! I also use it in the forks of my bikes so that should blow everyones mind for sure. ..................lm
