100k Lr3 best oil for high miles

I change based on when the vehicle tells me. Changing oil too often can result in long-term engine damage from additives in the fresh oil that dont get time to break down between short intervals and thus build up. There is some tech data and write up online about it. But really you would have to own the vehicle for 200k and be changing it every 3k or less. In this day and age, no one should be changing oil any less than 5k miles. Or by any specific date. Those oil change places are the biggest scam when it comes to intervals/dates.
Keep in mind one of the most wasteful institutions on the plant, the US military, actually does oil analysis on vehicles before deciding if they need a change. The result is most Hummers, for example, ran oil for over 12k before a change. This is first hand info I got from a buddy who's job was literally to do oil changes on military gear and send out samples for analysis. So even they did not change oil for the sake of changing it based on frequency, etc. My BMW can go about 10k between changes on Mobile 1. Also your oil volume will dictate frequency. My BMW holds 8 quarts of oil. The Rover, for its engine size, has a high capacity also at 8 quarts because of the deep sump. My Mark VIII only used 6 because of a shallow pan design, so changes were around 4k miles.

Say I send in oil with
only 500 miles on it
one with 3500 miles on it
one with 5000 miles on it
0ne with 15,000 miles on it
I read a review and one guy said his regular oil with cheap filter could go 15,000 miles based on the analysis. he did not say exactly what it said though.
I can tell after an oil change at 5k the engine runs smoother, can feel it in the gas pedal revving it. Can also tell using the dipstick and inspecting it visually and also rubbing between fingers vs new oil.

HI. sorry about necro-bump..Getting ready to change the oil on my new to me lr3 v8; i have syn 5w-30 in my hand, but can use dino oil as well; have it on tap at work; i probably will use the synthetic this time; also are people really going 7.5k miles on lof changes? why would you?
I have no idea if PO was running synthetic or dino so I will try synthetic; I will report if any leaks occure after this LOF.

We go 7.5k miles cause that is what is recommenced. Only the sheep change every 3k and that is only based on old engine designs with carburetors. There is no real reason to change any sooner with regular during (not towing) and with synthetic you can easily go longer. My old BMW was 10k on synth.

Seriously tho recommend perfect conditions not dusty, towing, dirt roads, mountains, etc... Is it a money thing? recommend by manufacturer. Some manufacturers say that transmissions and differentials are lifetime fill....
Doing a LOF is the easiest way to catch and manage other problems earlier. just my .02
