We all should check the oil from time to time. But I'll admit that I'm one of those that rarely checks it. But depending on the year of your vehicle you could be setting yourself up for an expensive failure.
Want a real shock call your local dealer service department and ask therm what the manufacturer deems is acceptable for oil consumption during warranty. I worked for Toyota in the 90's and the acceptable consumption was 1 quart a month. I wouldn't be surprised if it's the same today. My kids little Nissan Versa has a 3 quart sump. So if it was burning a quart a month it would be out of oil before the oil change came due.
