I'd have said 95-98 M52 six cylinder cars and the 93-95 V8s.

I'd guess they're meaning the Nikasil problem. Do a search on this for
chapter and verse - but in the UK I'd ignore it. The fuel responsible
hasn't been around for many a year, and any damage caused by it would have
shown up long ago.

Well that is what I understood too as far as the V8 was concerned. I
did not know about the M52 problem lasting that late though.

M52 was problematical until it became the dual-VANOS M52TU in March 98.

Really depends on where you are located. There is NO problem with the
M5x series engines in the US.. until they got it sorted out - the M5x
engines still came with a cast iron block, and then with steel inserts
in the aluminum blocks.

Apparently the Euro cars weren't as lucky.

No 'problems' except that the E39 was designed for an aluminium block
engine and the cast iron one didn't handle as well.

Euro cars run on Euro fuel - ie that from the Euro suppliers didn't
suffer. Those run on fuel refined abroad and imported and sold at 'cheap'
outlets may have done.
