Hey guys! Looking forward to picking up my car, been riding motorcycles for the last couple of years, looking forward to a few more creature comforts. I took a pretty good look & testdrive of the car upon first checking it out and the only thing that stuck out was the intake was rattling, so I ordered 3 new rubber mounts. Now I would love to change all the fluids, amsoil recomends 5-30 but I feel this may be too thin. Walmart carries some mobile one full synthetic turbo diesel truck oil in 5w-40, should I just start with that?

Thanks,
Mike W.
