All current Bitcoin Core releases will consider spends with a scriptSig above 500 bytes non-standard. It will likely be raised to 1650 bytes in the next release.

For plain multisigs, as far as I know only Eligius will mine transactions with n>3 as they're non-standard (so not relayed).

That being said, multisig is now usually done using pay-to-script-hash. In this case, the only limit you're facing is the maximum length of the scriptSig which is 1650 bytes. If you do the math, you can go up to n=15 safely in that space.

TL;DR Up to n=15 in a P2SH, stick to 3 otherwise.
