I've thought about trying Blackstone, but since they don't include the TBN it kinda puts me off. The rest of the numbers let you know if something is way off, but as I understand it the TBN is the best general indicator of oil condition.

And yeah, it's definitely time too. Not just changing the oil, but deciding to change the oil, getting the tools, putting it all away, going to buy the oil, etc.

Damn I can easily do two oil changes a year on my Ninja cheaper then that.
New oil doesn't need to be analyzed.
I don't test new oil.

The frequent tests is only on the Prius because I want to see how the oil changes at time, and when it goes bad. On the bike it's just once yearly for personal reassurance, along with the oil change. On the Prius if I were to test it every 6 months, I'd be wondering exactly when it deteriorated in a measurable way. And thats because I still haven't found out how long it takes for the oil to go bad. If it takes 3 or 4 years for oil to be measurably "bad", which for starters would be very interesting, than instead of changing the oil yearly I'd just test it yearly. 15$ toolless test that doesn't even get me dirty certainly is easier than any oil change.

3 or 4 years without an oil change does sound heresy on an automotive forum. At this point I'm just curious.

If there was a factual reason to change oil every 3k miles, I'd wanna know. I just can't find any actual evidence to support that.
good info.

I'm still going to change mine every 5k miles (regardless of time) just so I can keep track easily and for good measure; it brings me peace of mind. considering I drive a truck and 3 motorcycles, that's only about 2 oil changes a year that I have to perform anyway. It's good to know my oil is safe even if I double the mileage on it, though.
