Engine oil Castrol or Motorcraft

I'm personally running Castrol in the BMW bottle.

Got some numbers for the oil pressure Water temp around 90-95C/194F. Ambient temp 28C/82F Oil 5W30 Castrol Edge LL Hot idle 20 PSI 2000RPM 60 PSI 3-5000RPM 70 PSI Looks okay?

My co workers wife had a high mileage Sienna 3.0. Oil leaking from every seal. We started using Castrol high mileage, it stopped leaving spots in his driveway and quit loosing 1.5 qrts between oil changes.

I have stuck with manufacturers till manufacturers recommendation is causing issue, like my gixxer leaked entire oil from companies estar engine oil, switched to castrol power 1, no leak, headache gone and happy riding on it for about a decade now.

Castrol/Mobil1 5W-40. On my JK I change it every 7000 kilometres MAX

the regular castrol gtx high mileage green bottle. I used to use it for a kia rio same as accent and the burning went down a lot

I use 5w-30 Castrol and she runs like a

Dream.

I use Castrol Edge 5W30 LL04 (M). I doubt what you read about sludge is true. Regular oil and filter changes are way more important than which brand you use.

I use the Castrol 10w50 that the dealer gives me for my 18 RS. I have clutch slip issues and it seems to keep it mostly under control vs Motul 7100 or 300V

I noticed when the castrol 508 spec wears. It smells Faintly of onions and beans. Strange smell indeed, when I took my car to street side VW out of Amarillo, Texas.
