The suggested oem synthetic Mobil oil is a good one I have used. I have bought alot stuff from Viperstore or http://www.jtsvp.com/. And filters from local dealer when in stock…. Enjoy!Hi All, pretty excited to own my first 2006 RAM SRT 10. Can anyone advise best engine oil (brand and grade) as well as best place to buy filters and all other parts. I am located in Australia so they will need to be able to send internationally. Thanks in advance.
