I have a very low mileage Dodge truck that I recently pushed the OCI to 21 months on (but only 3,700 miles). I am still waiting to hear the Blackstone results from the old oil from that change. While this truck does not see a lot of driving, it is hauling a camper for about half of the mileage it sees. Everyone's vehicle usage is different, so I recommend getting the oil checked by Blackstone if your use does not fit a normal pattern (or you are pushing out the OCI). I will probably not test my motor oil in either vehicle at every change, but will test from time to time.

Don't try this at home, but back in the early 90's I ran an old Subaru for over 3 yrs/36,000 miles on one oil change (AMSOIL 10w-40); however, I had installed a by-pass filter (that filtered down to about a tenth of a micron and absorbed water) and I changed it and the full flow filter annually. I don't have the documentation any more, but I had the oil analyzed each year prior to the filter changes, and the analyses always came back satisfactory. The only reason I changed the oil when I did is because I got carried away with a can of carburetor cleaner and I thought I might have contaminated the oil with it. Ohio winters finally got to the body, but the engine was still running well when I sold it.

It's all "feel good." No science to it at all.
Get the oil tested when you drain it out. Find out how much life is actually left in the oil you are throwing away. With a synthetic motor oil, it will likely be a good oil you are throwing out. But only the lab can tell you for certain. "Feel good" does not work.
