Sorry to bring up an old topic, but i have not seen many recent posts and things change with technology. should be an easy question for all of you oil enthusiasts, I have an 04 Rucicon that is my toy. It gets about 3000 miles per year on. Mostly sits in garage. I currently run Amsoil Sig series 10/30
I have been reading about the M1 Delvac 5/40 as being an excellent choice. I only change oil once per year, Is there any better choices for my situation of barely driving that would better fit the flat tappet engine? Or stick with the Amsoil?
