Does M54 burn oil?
If you were to do an engine rebuild, you could replace the rings with those from the M52TU motor, as our friend 50sKid is doing currently with his M54 rebuild. I highly doubt an engine replacement would solve your issue for long, as any other M54 you find will likely burn oil as well, at least eventually.
Can I swap a M54B25 to a M54B30?
Re: Engine Swap: M54B25 to a M54B30 IT’s basically the same block, only different stroke (maybe a few grams difference because of the different intake, sound generator etc). But biggest problem is the ecu. You not only need the ecu, but also the ews (or recode), throttle body, maf (both differ from 2.5i).

Is it better to run an M54 or E85?
The M54 engines do respond better to the higher octane fuels and running E85 allows better performance, if you get the tuning right. We must stress that maintenance is kept up, the only issue people seem to have with these is where they have neglected basic oil and filter changes.
