Welcome to New Member - JonS June 26, 2018, 01:23:53 pm Quote from: JonS - June 26, 2018, 07:00:43 amI have driven a lot of miles in my work trucks and have always changed the oil every 3000 to 5000 hiway miles. One pickup had 300,000 miles and it's replacement now has 500,000 miles. In my book, oil is cheap to achieve longevity.Hello Jon. I see you're new to the LDO Forum and so I'd like to welcome you. I think you'll find this neighborhood is especially friendly and as importantly immensely helpful on all things related to Lazy Dazes and a few other "odd" topics. When you have a chance, it would be a great to learn more about you and your RV plans. We look forward to hearing more from you.P.S. A cut & paste from another topic so as to not hijack that issue. 1 Likes
