Extended the intervals out a bit more on this UOA. I will probably keep it at 6-7k intervals here on out. This UOA was probably 60% of highspeed highway, but also mixed very short trips - lot of short trips to the grocery store and to pull the car in and out of driveway when I use the garage as...

Sharing another UOA. Usually use 0w40 GC but decided to use up some 0w30 I had sitting around from 2018-19 ish. LL01 label on there. I daily drive the car about 7 miles each way to work (mostly freeway).

I stretched this oil out little farther because past results were decent on that 5k interval run and because this one was quite literally, half freeway trips. I did about 5-6 trips from LA - VEGAS which were 250 miles each way.. so 2500 miles were guaranteed to be all freeway, and the additional...

Sharing another UOA. Half the trips were freeway miles this time, other half very short trips. Interesting however that there is fuel showing up in it now though..

Just sharing another oil change - again using the good old Castrol 0w40. The next UOA will be edge 0w30, I have to use up my stock from circa 2017-18 LL01 era. This gets daily driven about 7-8 mile one way to work everyday, high rpms and WOT runs here and there for good times of course.

I actually wanted to run a 2 year drain interval because of the low miles on the oil but decided just to pull it after 1.5years. Looks like 2 years would be no issue at all. I never used Ravenol before so was afraid of possible oxidation but looks like it did fine. Background: The car typically...

Just sharing another UOA, first one on the motul xcess gen 2 5w40. Wear on iron seems consistent , this car does make frequent short trips to the grocery / idles often, but half the miles on this UOA consisted of higher speed 80mph+ desert trips to vegas in 100F+ weather 250miles one way. Not...

Just sharing another sample. Wear is trending very similarly, can't complain about 22 dollar oil per change. Always been a fan of gc/bc edge. Daily driven , about 7 miles each way plus some spirited runs here and there. Not much long highway trips.

Interesting how this BMW 5w30 oil sample sheared so much compared to the previous sample which was BMW 0w20. Seems like fuel dilution based on the flashpoint. Lot of idling (napping baby / toddler ) short trips but many small road trips 100 to 300 mile one way this interval. However car had been...

Daily driven 7 mile each way to work, occasional long trips, multiple redlines and high revs due to the short gears and turbo lag (when warm of course). Flashpoint did a lot better here than in my Direct injection m4 with the same GC 0w40. Also running a catch can as the only mod, stock...

Please see attached for UOA. The Castrol 0w40 Edge used in this was from 2017-2018 and still had the LL01 certification, commonly known as BC / GC here. One of my favorite oils up until it lost LL-01, but I still use it in other vehicles I own. I don't understand why flash point on this car...

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...

Shocked me when I saw on my service paper from my last oil change at dealer they filled with 0w20, they said probably a typo. However, just got a blackstone UOA back that showed cSt Viscosity @ 100°C 8.20, meaning the dealer did indeed use BMW 0w20 in my BMW M4 that originally came with 5w30 /...

Long time lurker here, always slightly intimated to post on here especially with such different viewpoints and biases I myself have been a GC 0w30 user when it was green back in the day, and gravitated towards BC 0w30 and GC 0w40 now. Having owned all BMWs, LL01 was always what I looked for, and...
