We're going on a family trip in a couple weeks. Looks like total trip miles will be roughly 3500 miles. Our 2008 Honda Odyssey currently is running PU 5W30 with about 3700 miles on the oil. Given all the previous posts about how hard the Odyssey engines are on oil, should I go ahead and change it out now? Current oil life monitor is at 50%. If I change it out now, I was going to put some Peak conventional 5W20 oil in...go on the trip...then change it out when we get back after running it until 4k miles total on the oil.
