I am going thru the same thing for my 2015 X5 35i, did you ever run with a cheaper alternative that is the same weight and GL-5 like OEM? I also found a cheaper Honda alternative that seem to be the same spec but says that it is specifically formulated for Honda.

The N55B30T0 in the M2 uses standard powder forged N55 rods, a different forged crank than the S55, and the pistons are derived from the S55 but they are not identical (first piston ring is a different design) due to the LDS lining used on the S55. And the rod bearings are the same across all...

Thanks, I already have some running in my X5 35i, I will test when I change it again.

Yeah, it still is.

Have you done a UOA on this oil? This stuff is on close out at Advance Autoparts and dirt cheap.

The price for a 5qt jug of Edge 0W-40 A3 on Amazon has doubled and Walmart doesn't have any available. Purely supply chain issues?

I emailed Castrol, we shall see what they say.

Well it can't be that catastrophic if they are running the engine during the tests and logging all of the pre ignition events. https://www.swri.org/sites/default/files/sequence-ix-test.pdf

I am pretty sure they all do, how many pre ignition events occur or how severe varies I guess and there is an ASTM test done that documents these pre ignition events. Although this is more of a concern on on smaller direct injection turbo engines so it may be a non issue on my 3.0L inline 6.

Amazon always has it, I get Castrol on a subscription from Amazon for $22-$25 for 5 quart jugs

AFAIK, all direct injection turbocharged engines experience LSPI to some degree.

Yeah I am just curious, I am sure the difference for me would be negligible. I have a BMW N55 with an upgraded turbo, E50 tune, water/meth injection, etc. and I change the oil (Edge Euro 0W-40) every 3k. But I have seen that SP rated oils are better for LSPI, etc. on direct injected engines.

Specs look a little better on the Edge SP. This is the link for Edge 0W-40 SP: https://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/B2770E2EF26BC3C38025858B0060363B/$File/wepp-bqut2h.pdf This is for Edge Euro a3/B4 0W-40...
