~~~~dalola~~~~Thanks for the help. I certainly shall follow that advice for at least the first two
oil changes. Did the rep say amything as to why not
synthetic multi vis ? Or is that Mobil 1 multi vis? I have not used it....although I hear it's good,...my brand has been Castrol.
~~~~Bob In Ct~~~~ I tend to agree, use the lowest viscosity that is safe...my trick always has been, in the summer, or in a hard used or hot running motor, if possible, add a few quarts of heavier
oil first, (20-50) during the
oil change...then top off with the 10-40 or 10-30...that seems to give a chance at least for both contingencies. I will not be driving my cobra during the winter, and If I do, in an emergency of some kind, it will at least start the first time in a heated garage...(good idea about a cover for the oil filter, I assume you mean a port cover, do you mount that on the grill? With ties?) so at this point, barring more data, after the first two oil changes, it will be either standard multi vis oil such as Mobil, or Castrol, OR multi vis
synthetic...my original plan was to blend the two.....I am doing so right now in my F350 hi cube truck, 460 motor...I am not using straight
synthetic because it uses oil, and it would be a waste to use straight synthetic on the old girl, and I figure the standard oil may soothe the old gaskets a bit. Maybe it's faulty theory ?
If it is a good idea, I will use the full 15-50 synthetic, the castrol synthetic is 5-50, which also sounds good to me.
