I hate to start another oil advice thread as there are as many threads as there are oil choices but I wanted to ask for advice given my vehicle use. My truck is not used as a daily driver and may go up to a week and maybe 10 days between use. There are days where it may get driven a few miles every day for a couple weeks. It's not a work truck and doesn't get driven hard. I generally commute by motorcycle and unless the weather is poor or I need to take the kids with my vehicle somewhere it doesn't get a ton of use. When summer roles around it tows a 3500 lb boat around. I take 8-10 trips with the boat 200 miles round trip. I've ran synthetic Amsoil when I used to drive it for work put many more miles on it. My question is what would be a good oil use for this situation. I'm lucky if I put 2500 miles on per year. Should I go back to a dino oil and just change yearly or continue running the synthetics and how often to change with the low mileage. I run a dual remote bypass filter system as well.
