You make a good point. When using a full synthetic oil, I would feel more comfortable following Honda's extended oil change interval.I changed from the HP-4 to Honda's full synthetic in my '06. It performs well, as I'd expect of any quality oil. I like the idea of using fully synthetic oil for better lubtication at start up. I also run the oil to Honda's recommended change intervals, and synthetic is better in extended service. I buy it by the case from HDL.
Same here! BUT....I change at 4,000 rather than 8,000. Trans has smoothed out. I do have only 120,000 miles so, we'll see. :yes1:Shell rotella T for me, cost less, same protection. Yes the clutch was smoother at first, but that is common with any oil change as far as I can tell. As the oil breaks down the smoothness goes away. It is a clunky transmission by nature.opcorn::beer3:
