This is a question. Has anyone driven with a 'good' 561 and just changed to the more reliable 951?

When you did that, were there any positive affects like gas mileage or better Emissions? I always get paranoid about Emissions on teh day of my cars inspection.

I have a Blue tagged 561 in the trunk and although there is nothing wrong with my original 561 in the car I was wondering if there is a benefit to just swapping them and leaving the 561 as a spare.
