a couple of years back, i bought an 87 cab that had run out of oil and spun 2 rod bearings. bonus for me. carreras do have a tendency to use oil in varying amounts due to worn guides, worn valve stems, and crispy, broken stem seals. say it uses a quart in 300 miles, which some do about the time they come in for that top end job. that's 10 quarts in an oil change interval of 3000 miles. if you're a doink, and never check your oil, the engine looses it's bearings.
