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...
The 0w30 I pickup when it's cheap but other than that I will take the 0w40 5qt tanks at once at amazon / walmart. Keep in mind that the 0w30 did see the highest mileage interval so far so that could factor in the more pb shown.
As far as extending the drain intervals, I'm sure 5k+ would be no...
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...
Yes. It's trending down though so I'm not worried. The intervals before this one consisted of horribly short trips - wife took it to the store once / twice a day to grab groceries, less than 5 min drive each way. Also, lot of idling while letting the babies sleep. This last interval was the only...
For those wondering starting from the far right column and moving left, first was factory fill BMW TPT 0w20 LL17 filled under the BMW free service period, followed by BMW TPT 5w30 LL01 SOPUS, then Motul 5w40 Xcess Gen 2 LL01 for the last two UOAs.
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..
To answer a couple of questions -
1) Car isn't modified, stock intake stock tune
2) Factory grade recommendation is 5w30
3) Yes, I'm sure i could extend the intervals but those of you familiar w/ the EJ25 turbo and its issues across the years could see why I prefer to shorten the interval. In...
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...
5w30 tpt was always available for me to purchase and I did exactly that, but yea dealer would opt for the lighter weights . It wasn’t always easy to find so I bought bulk when I could.
