I had the one in my '83 Cherokee (full size) do that. I thought it was the rear main seal, so I spent the night of New Year's eve '99 changing it. Didn't see any leaks, so I drove to Canada and back, but I had to stomp on the gas to merge on I-5 at Bellingham. About 30 miles later I heard a horrible knocking noise.
I put 3 quarts in and saw it was leaking. First time in almost 40 years I didn't have tools with me so I finished driving home. I stopped every 10 miles and added another 2 quarts, but my case ran out 25 miles from home. I dropped my son's then GF off and said screw it! If it blows, it blows! (3AM on a sunday night)
I got home and shut it off as I cruised into the yard. Next day I filled the oil and swapped the sender. Didn't lose any more oil, but the 282 (Mexican six the stroker was based on) was shot. All the pistons had chunks out of them when I stripped the motor down.
