I recently bought a 2021 BMW 230i. Car has full wtty for abt a year and CPO after that. Just before my purchase the dealer did an oil change and they used 0W-20. I'd feel much better if they had used 0W-30. I would never wait the full OCI but wondering if I should change it really soon? I...

My niece just got a 2023 Countryman. The manual recommended oil is LL-14 FE+ or LL-17FE+. From what I can find, these will be 0W-20. Would you advise her to go with something like a 0W-30 or even higher viscosity? My gut is 0W-20 is all about fuel economy. Some say these engines (B48) really...

Mileage and time interval since the prior change are correct at around 1,800 miles and 20 months. The prior oil change interval was approx 1,600 miles, not 52,000 shown. I tried to make as few short trips as possible, but there were quite a few 15-20 mile roundtrips. The only thing that struck...

Approx 1,700 miles on the oil. Virgin KV100 spec for this oil is 13.1. Last o/c a year ago the KV100 was a little concerning at 11.43. This one is a a surprise how little the KV100 degraded. Same oil, about the same mileage. I tried to not short trip as much, often taking the long way home...

Slow getting this out here. This was an very short change interval mileage wise. It was a year from the last change and I've been going on 7,000 miles or a year - whichever comes first. The car does often see short runs (~8 miles) Blackstone thinks I could wait longer. I do my own changes and...

I have a BMW with the N52 engine (na, port injected). The car only gets about 3,000 - 4,000 miles / yr. I'm changing oil once a year regardless of mileage. I try to not use the car for a 2 mile errand, but do make a few 7 mile one-way trips. It's been suggested that I even shorten my OCI because...
