Our first trip in our '93 with 8v92 I was towing a silver Miata. When I got to Creede it was covered in oil. I had an oil change just before the trip and they filled it to the full mark which was too much. After that the oil consumption was very little, only a couple quarts between oil changes.
It's worth the time to determine your proper oil level and mark your dipstick. And make certain whoever is doing the oil change knows which mark to use.
