so here's what I have found regarding UOA's in the real world of dealerships and service. UOA's are not telling a full story. for instance, we have had several customers bing us results of the analysis, but their engine is using oil. what the UOA doesn't tell is the stuck ring situation due to extending oil changes causing the rings to stick. we don't care what oil you run in your vehicle, if its not changed at 5,000 miles its GOING to use oil north of 90,000 miles. I have seen it too much, especially in the import market Nissan, Toyota, Honda. we have replaced several eco boost due to extended oil changes. if you read the severe service and normal service closely and with a fine tooth comb it says if you live in extreme climates hot or cold, driver oil the city, any idling, you fall under the extreme serve ice category with is 5,000 miles or sooner. there maybe 1% of people that fall under the normal service category. I haver a coin right now whom is a broad that has a 2017 Honda accord with a K24, she asked me a few weeks ago about her car that it is burning oil. I asked how many miles she said 110,000. I asked how often you change oil, she said when the oil life monitor displays change oil which she said comes up at 15%. dealership serviced the vehicle. also have an acquaintance, whom has a 2017 f150 coyote. he asked me to come change his transmission fluid and filter he said it has a torque convertor shudder. while I was there doing that he started asking questions about why his truck is burning oil. it has 135,000 miles on it. I asked him if this was the first time he replaced transmission fluid. he said yeah, I laughed and I said I guess you change oil when the oil life monitor tells you as well, he said yeah. I said who changes it. he said Walmart changes the oil with mobil 1 5w20. I told him you waited to long, 5,000 miles and no more. now he has an oil burner at 135,000 miles, and a torque convertor shudder. he needs a new convertor and well the engine is what it is. also working at Toyota with this lovely 10,000 mile oil change intervals. we have the customers who we tell 5,000 miles and they do it, we also have the ones that y'all are trying to get money out of me bc Toyota says 10,000. we tell them to look at the manual at severe service and normal service. well guess what engine is using oil at about 100,000 miles on the Toyotas. its there exact same results stuck rings due to extended drains. its the same ole story with Nissan and Honda. this is real world for several manufactures. this is not speculation. any ford, we did diesel oil at 5,00 miles as well due to the EGR and the dilution for the regions.
results… they should be ashamed.

I also noted in the comments I want him to make a video like he ask about w/r to the M1 and the change in formula.
It has had 9-10k oil changes since new and now has 150,000 miles on it. Only consumes maybe 400ml of oil every 10,000 miles.
