Dennis,
RE: "Start off with the same oil that you plan to use."
I was planning on running the 15/50 Mobil 1 Synthetic, you think it's
Ok to run that from the first oiling of the engine onward?
I thought that was not to be done.
Also I thought we should only be using the (Mann/Mahle) Oil Filters? I
thought I understood you saying I should use "Mobil 1, Fram Tough guard,
> and Purolator Pure One are amongst the most efficient out there."
> Where do I find the exact model numbers I should be using?
Little confused and I really can't afford to screw this up.
Thanks your assistance,
Robert
