Thanks Pete. I am beginning to regret asking this question. I was serious about it. I am not cheap, but since Premium is over $3.15 a gallon, I wanted to consider other options. That's all. I truly wanted to know...not just to save money, but wondering if it can be done, that's all. I thought it was a reasonable question. If I had seen the previous thread, I would not have asked a question that has been discussed before...especially when someone suggested that people who wanted to save "a few cents" were cheap. Anyway...

Thanks for your reply.
