Review: Performance oil - Excellent product
Review: Best oil for big V twins. - I started changing my own oil a few years back and tried Red Line for no other reason than the reviews. I have 2 bikes with 103s and an older 88. This oil is amazing compared to the garbage HD uses. You will literally hear and feel your motor run better and quieter. No more clunking or lagging with the throttle. It seems to run so much cooler and smoother. You will not be unhappy with this oil. As a side note, I also use Red Line Primare oil and gear oil and notice a huge difference with them as well. Red Line for all 3 holes.
