Engine oil Castrol or OEM BMW

On my M135i F21 LCI, I always let the initial cold-start finish until the idle drops and then start driving while not going above 4.000 for the first ca. 5km and not giving full gas until the engine oil temperature is 72c or more.

Been doing that and till now no issues or leaks, the engine is running sweet.

I do a 5K oil change interval. I let it warm up for 5+ minutes every morning. Not necessarily because I'm intending to warm it up to operating temp but because that's just how my morning routine goes. I drive moderately and keep the RPM's below 3K and try to keep below 50% load on the engine, aka drive moderately.

Oem Bmw 5w30 longlife 04. I used this for 8 years in my high mileage n47 and sold that thing mint. Go with oem and don't waste a second more thinking about it. Enjoy the car. Just do the changes on time or early and it will be good.

Preferred Castrol edge 0w-20 during the warranty period and 5w-30 after the warranty period. The engine is quieter with 5w-30.

The ss will have Castrol that they use for big bikes it’s better than prolube and Motul 7100 in my experience.

I just use Castrol magnatec 10w40 here in the Netherlands in my m20.

The closest I found was Castrol? Long life 507 which was £40 for 5L from Amazon, but I had to buy the stuff direct from VW as was pushed for time for my oil change (with a friend).

Although even if my Manufacturer recommends 10w30, I'll still go for that Castrol Power1Ultimate 10w40. It's such a Buttery Smooth Oil.. that's the best gift you can ever give to your >200cc motorcycle.

I'm at 308k miles and use cheap Castrol engine oil, house brand transmission fluid (the correct kind though), and the cheapest coolant I can find.

Castrol sucks
