The new formulation has a tiny "FS" on the label (fuel saving?). The new formula is slightly less viscous according to specs I've seen published over at BITOG. I don't know if it couldn't meet LL-01, or they didn't bother since they knew LL-01 was going away. Perhaps BMW even quit certifying by that time?

The change to Castrol Edge is very recent, so I don't know about that one. I presume similarly that there was at least a slight formulation change and one of the above reasons resulted in no more LL-01 certification.

I still have several jugs of Castrol with LL-01 on the label, and after that, I'll probably just keep using it as long as it's readily available at an appealing cost.

The rod bearings were barely to the copper, and only on two of them. The oil analysis picked a minimal copper reading, there was no need to even polish the crank. Everything in the top end was pristine.
Interesting. No manufacturer, including BMW, recommends warming up your engine that much before driving. I can't imagine that was your issue. And if your max OCI was 6000 mi, that shouldn't have been a problem either. Are you sure there wasn't some other factor that caused your rod bearing failures? I would suspect something like coolant ingestion, low oil level, or some other oil contamination. I guess one can only speculate at this point. Glad whatever it was that it didn't cause more damage!

Yes actually, low oil level.

I’ve always been a Mobile 1 guy, but the sticker in my engine bay says, “USE ONLY BMW SYNTHETIC HIGH PERFORMANCE ENGINE OIL”. So I was like, ok I am new to this and did so. She would eat that oil like kids eating birthday cake. A couple of times she was almost two quarts low, but never low enough to activate a oil light. The rings are fine.

Then came the blower, and surprisingly it helped with this problem. The truck actually ran better, and not from a performance perspective, but from a daily driven. I was still eating the the 5-30w, Mobile 1 at this point, but very little. So I figured, I’ll step it up to the Castrol 0-40w. She was eating it again, so back to the 5-30w.

Now we are running the Pennzoil Platinum 5-40w. It just has a different feel. I took her to the top a couple times to check for a slight miss, and it just seem like a superior oil to any that I’ve ever used. As far as consumption, I’ll need to put a few more miles. I will give a update.

The M54 and oil consumption has been a unique experience for me. Everything checks out, compression, engine wear (other than the rod bearings). The truck performs like a beast.

Yes, definitely let us know if it helps your consumption. My understanding on the M54 oil consumption issue is that the oil rings are very low tension and any buildup can cause them to let oil past. I'm not sure if my old M52TU had the same issue, but I don't think so, as I think it had different rings.
Definitely a good idea to keep OCI's shorter than BMW's ridiculous 15K miles! I go 7.5K miles which is about 9 months for our vehicles.

Yeah, the M52 has different rings.

The one good thing I have going for me is, the amount of water/meth passing through my head is steam and chemically cleaning any contaminates from my top end. So as long as I keep the bottom end clean, all should be well.

I’ll need to think deeply about changing my oil every six months.

I am also curious about the percentage of pump pressure bcredliner’s meth kit is pushing? My max is 80% on a aquamist system.

Have put a new filter and Castrol Edge 5W 30 LL01 as recommended by my indy in and all good so far....


Here is a scenario that I have experienced. It might be different circumstances, but at the end of the day it’s all the same.

Anybody?

Snow meth spray is regulated by the size of the jet. A little goes a long way. The pump can handle a jet that is for much more HP than I have. I use a 400-600 HP jet. I have a Snow controller and use the injector pulse width option to regulate meth flow. I have it set for 100% at 75% pulse width.

Most of the time I don't use the nitrous so I am still using the Dinan tune that is matched to the Dinan engine mods. The Dinan tune advances the timing. Normally the timing is retarded with a nitrous tune to prevent detonation. Detonation with juice flowing is berry berry bad. The primary reason I added meth is to be sure I have high enough octane to counter the timing advance in the Dinan tune. I only use Snow boost juice which increases 93 octane to the equivalent of 103-108.

I’ve always thought meth injection on N/A was a good idea. Just a bit of added security for the tune, but also the benefit of how clean it keeps everything. When I took that DISA out it was super clean, and that was after years and years of operation. So I’m sure the deposits are minimal in our chambers.

There is no intercooler for the RMS X5 supercharger, unless you use a intake manifold from an older i6. I am not a big fan a Frankenstein. So I went with the meth injection.

I can easily go through a gallon in a day if I’m acting up. LoL.. I make my own juice.
