ON CANDLE SPELLS DO U HAVE 2 USE OIL??,IN ORDER 4 THE SPELL 2 REALLY WORK?????

No, but sometimes the oil can inhance it, depending on what it is you are trying to do. For example, bay oil would be good for protection.

if you are doing a candle spell it would inhance it more for working if you have the right colour of candle according to the deity you are conjuring for the spell purpus and if you have like say water, or earth if this is related to the diety and incence all inhance the chance of the spell working.
Blessed be
