Engine oil Castrol or OEM BMW

I use the castrol gtx high mile full synthetic 10w-40 and a sohn adapter with ideimitsu. I’m sure non of the name brands will hurt As long as you change it frequently.

I change every 10,000 km - 7000 mi.

Castrol or Mobil full synthetic.

To me that is much better than running any brand of oil longer.

I’m a Castrol 0W40 guy myself.

It doesn't seem like I burn any oil in my Rabbit. 0w-20 seems too light to me, also, I'm running Castrol Edge 10w-40.

I run Castrol GTX 10w40 in my FD. Premix TCW2 2stroke oil .5oz/gal.

Engine seems happy as can be.

I use mobil1 or castrol full synth 0W-20 for prius engines below 200k and 0W-30 for those above it. More than 30k mi now so far so good. I like the castrol better bec my engines sounds much quieter vs m1.

I use castrol magnatec beucase it has some kindof ionization tech where it sticks to metal surfaces to reduce start up wear which the prius is constanly starting/stopping.

As someone who lives in Florida, and has a high mileage m54 motor, I only use Castrol 5w40 and 5w30 if I cant find the first option. Runs amazing and daily driven with some abuse lol

Go to wallmart and buy two jugs of Castrol Edge Full Synthetic 5W-30 and then just purchase a couple filters off of FCP Euro.

I've used both, M1 was quiter and yes it did burn a quater quart more in the same period.
