In many BMW with 8HP trans from ZF my family members go with Valvoline. This oil works great in this trans. And anytime you change oil in this trans you should do 4x pan drops. I’ll go this way when my Mojave will hit 50.000km.
100km. Ive change to Mopar 5w30 which I bought at Dealer. Then after first 1000km Valvoline 5w40. Then every 5000-5500km Valvoline 5w40. Now i have a little more then 31kkm.
Valvoline 5w40 from new, now 31kkm. Oil change every 5000km. Only one Mopar 5w30 when I take it new from dealer. I bought there this oil and change it at first stop, after first 100km. Then after first 1000km Valvoline 5w40. I don’t care about warranty. Nawet used this on any my vehicle.
