Just fitted a new xtr 9 speed chain to xt cassette.
Problem is it's sucking up around the front ring.
Pretty sure it's the same type of chain as before.
Could the thick shimano oil coating cause it to suck in?
If not anyone any ideas please?
Classic problem with new chain on worn rings. The answer is very simple: change the chain ring(s)

Until your chain wears to your rings the problem won't go away without replacing rings (and cassette whilst you're at it? - IME you'll replace the rings and suddenly have skip/slip which wasn't there whilst you had the chain suck). Of course by the time your chain reaches the point is worn enough to not suck, if you're a regular chain changing rather than an occasional full drive train changing type, you'll want to replace the worn chain again any how.
Thank you for your reply, it's just a single ring thankfully
As above, change the ring - the worn chainring teeth hook the new chain causing suck.
I tried the 'have 3 chains, change it after every other ride' for a while but still got skipping. Now I change the chain and cassette at the same time and wear them into the ground with usually a new middle ring at the same time too.
You might be able to get a bit more life out of it by reversing the ring but best to change it.
Should I spend more money on a narrow wide, would it be of any benefit over a renthrel ring?
As above. Happened to me just the other day! New ring cured it
