Hello all. Just bought a Dodge caravan with 126k miles. I don't usually buy used cars so this is different for me. This is a one owner and serviced only at the original dealer. They have changed oil faithfully at 6k miles with dealer oil. I'm old school and prefer 3k changes. Ok, the rundown, Manual calls for 3k-6k changes, 5w30 oil. I live in Maine so the weather is cold winters and startups every day Cold! We bought this for grocery runs, but find it is much more comfortable so would like to use for our sports trips for the kids that include monthly trips 4-5 hours on the highway. The van has no known problems. Also, filter. I've read on this site that high mileage oil may not be the way to go. I think that's all the info I can think of. Thanks.
