My most recent contribution to this thread has to be amended. I took the car for a short trip to the mechanic regarding the oil pressure light. He was nice enough to put it up on the hoist right away. The pressure sending switch was leaking badly. I will order a replacement, and all should be well when it's put in.

The fact that this coincided with an oil change is a mystery to me, except that it probably points out another instance of crud that was sealing a leak being cleaned out by detergent oil.

I still wonder about running a multi-weight next oil change. The mechanic cautioned against it, recommending straight 30 or 40, as the straight weights are better overall for high temps. That's what I thought, too, but I know there are other opinions.

Remember, this is for a straight eight with regular tappets, not a V8.
