Any truth to this time limit oci are outdated?

Heard blackstone is telling some customers that modern synthetics ocis are primarily mileage limited rather then replace at set time interval. Any truth this generalization?
No one situation is the same and to each individual’s oil analyst is what should be followed per their vehicle(s).
 
A vehicle can be driven 1,000 miles a year in different ways. It will make a difference if time is a factor.

A vehicle driven 2 miles each way to work 5 days a week vs a vehicle driven 100 miles a few nice weekend days per year.
Both will be at ~1,000 miles in a year, but one will be so much harder on the oil and ready for a change, but the other is good for another year or so.

IMO, if you don't know and/or understand the difference in the above use cases, then you should stick with a time schedule.
 
My wife's grandma's car at most might see 3,000km in a year.

I still change it once every fall. Realistically I could probably do it once every three years and it would be fine, but my main concern is if i put it off that long, then i may forget about it until it is way past due.
once a year is easy enough for me to remember. It is also an opportunity for me to give her car a good once-over since i'm getting underneath it and poking around under the hood anyway. Doing this once a year seems like a good idea to me.
$30-$40 bucks for a new oil and filter once a year is not a big deal to me.

Considering the oil in my mother in law’s 95 540i with the V8 with 17,000 OG miles is at least 5 years old. I ran it last year just to open it up. Couldn’t tell any knocks. Would love to take a oil sample but it’s not my car, lol.

That’s a sweet car. Had a friend w/one back in the day; I loved it. Came within a whisker of getting one myself but really needed awd at the time and went w/an Audi V8. If I could find a very clean one of those, I’d still happily drive it. That 4.0 M60 was a great engine and wears well, and that E34 body styling was very attractive IMO.

I had a '95 740 back in the day. There was some concern at the time over the Nikasil bore plating, that could have problems with the high-sulfur gas of the time. It wasn't a common issue, and was most likely in engines which were babied which lead to relatively cool engine operating temps, leading to forming sulfuric acid which could erode the Nikasil. Sulfur has been mostly removed from the gas since 2000. Any M60 on the road today, would have long ago exhibited signs of Nikasil erosion, if there were a problem.

Nice ride. Take her for some rides in it.

My father in law when he was alive had dinan performance chip put in. I’ve driven it. It’s got some scoot for 95 technology.

It needs a new battery and an oil change. I know those are minor things but my mother in law doesn’t want to budge. I keep telling her to drive it, lol.
 
I asked Blackstone about extending my OCI beyond annual oil changes, as I wasn't putting very many miles on my vehicle annually and it took 15 qts to change the oil. Mostly only used it for weekend trips within a few hundred miles of home.
