UOA on my wife's car. Car was in warranty and got the run of the mill 0w20 from BMW every 6-7k miles, here's the UOA from the last of the free maintenance oil changes and I have since put in 5w30 BMW TPT LL01. Doesn't seem to be wearing as well as my cars that I have dumped LL01 in; double the universal averages, but my wife does frequent short trips in moderate climate (Southern California) that are sub 2 miles one way. We do occasionally do some road trips and weekend trips to take our child out. I'd say 50% short trips, 50% long trips in terms of mileage, but the daily short tripping is what made me pull the oil at 5k miles. Flashpoint still pretty high for a car that frequently doesn't get to operating temp often, overall TPT always seems to have decent results but this iron is the highest I've seen on any of my UOA. We shall see how 5w30 BMW TPT LL01 does on the next one in terms of wear. I don't think I've ever seen more than 10ppm on any of my UOA before at all, up to 5k mile drains. Blackstone says the double average of iron inside the oil is likely due to my short tripping and frequent idling with baby sleeping in car, haha.
