Anyone run Rotella T 10w-30?
I just changed the oil in my '4.0 L6 '88 Chokee this weekend. I refilled it with conventional Castrol High Mileage 5W-30. But now I am wondering, since it is so hot outside 5W30 is to thin for Summer time. I'm getting 40lb pressure moving me down the highway, it seems a lot lower than when I had 10W30 in it. My Ol' Chokee has 127K on it. Think I'm gonna switch it back to 10W30 and see what happens.

Moving me down the highway, rolling me down the highway, moving ahead so life won' t pass me by.
