I guess #2 below is wrong while the others are right whether we use either 'so' or 'as' in #3 and #4. Am I right?
1. I will go as far as I can go with it.(O) 2. I will go so far as I can go with it.(X) 3. So/as far as I know I will go to Europe in 3 months. 4. I will help you as/so far as I can.
Many thanks in advance!

All are in use and 'correct'. 'So' is usually reserved for negative contexts.
