Smooth shifting, reduced oil consumption
I was running my DL650 on Delo, but I didn't like how it shifted, and I was burning almost a quart between oil changes. I switched to Bel Ray on a road trip, and the difference was noticeable immediately. Shifts were smoother, and I can go 3500 miles without having to add any oil. I don't know why it works, but it does. It's worth the extra couple dollars.
