If you are buying American produced oil you are feeding American families. Keep up the good work! Otherwise consider extending your intervals to at least 5 k? I will admit the 7-8k MM intervals make me uncomfortable...But I'm not an engineer. I don't believe Honda is intentionally recommending damaging their engines even if it goes against my petroleum industry brainwashing of 3k oil intervals. I change at 20% Or whenever feels good. Can't change it too much I don't think, but why crawl under the car to waste money?Depends how you drive. I did my first at 2000 and then every 3000 after.
