I just put a deposit on a one owner 2002 dodge ram with really low miles, 62k to be exact but im a little worried. I have heard horror stories about this motor and oil related issues and was wondering if any experts have any advice for me. I think the first thing i will do is add a quality synthetic such as castrol or pennzoil. I have not taken delivery yet so im unsure of what weight to run but im assuming 5w-30. Thanks for any info you can provide.
