Simple Question: if my 280E, M110 powered W123 were running only on 5 cylinders, would it be obvious?

My ol' gal, she's running OK, but sometimes I start to wonder if 5 cylinders could masquerade for 6. Hey, Audi ran 5's for years.

The compression test is coming up next week for the scientific approach, but I was just wondering what you all think.

Waiting for warmer weather to get back under her to address the winter's deferred maintenance.

Thanks, Alex
