was and were?

[94BANSHEE]

hi are both of these sentences right?

"If I was you... "

"If i were you..."

it seems to me that i heard both spoken like this. the first meaning something that will happen in the future, and the second meaning something that happened in the past. for example:

"If i was you, i would go to the party"

vs.

"If i were you, I would have gone"

thanks

'Were' is correct in formal, and almost all AmE, usage. 'Was' here is an acceptable, although primarily BrE., substitute for subjunctive 'were'
