I am soliciting opinions from knowledgeable people regarding when to switch over to synthetic oil in a new vehicle. I recently purchased a Toyota Tacoma truck and realize that many automobiles now come with synthetic as a factory fill. I have read that because of the manufacturing processes currently used it is not necessary to use conventional oil for several thousand miles before switching over. For those individuals who are gifted in the petroleum science field - when is the optimal time to make the shift in a new vehicle and why (assuming that the conventional oil is to be replaced with synthetic)?

LubeMaster77, this has your name written all over it.

If someone wishes to increase their post count by suggesting a 'search' for this question please do not. I have closely followed the plethora of oil related threads for quite a while and have not seen an answer or an educated opinion for this question.
