Possible fuel in oil?
Last weekend my 94 burned #2 spark plug wire on my headers, resulting in that wire shorting directly to ground and a 7 cylinder motor. I did go to about 3/4 throttle once to see how it would respond, this was just when I first noticed something was amiss and before I came to the conclusion I was down a cylinder. After that, I had to keep it a gear lower than the conditions called for to keep it from shaking. I limped it home about 8 miles and haven’t driven it since.
I don't smell fuel on the dipstick but out of an over abundance of caution I'm considering draining $30 of Mobil 1 with about 800 miles on it. I know most of that unburned fuel went out the exhaust.
Is this reasonable or am I just wasting time, oil and money?

I would simply check your oil level, and if not over-full, do nothing. The small amount off fuel that might have made it past the rings of one cylinder will vaporize at oil temperatures.
Once I had an ECM failure on my '89 that caused the injectors to stay open. Through multiple start attempts, before I realized what was happening (gas smell, fuel coming out the tailpipes, etc.), I added about a half quart of fuel to the crankcase. I did drain and replace the oil in that case.
