Has anyone here used it in our trucks? If so, what do you think?

i have not used this in my truck but did run for a company hauling gas who used it in their KW's on 30,000 mile intervals and it seemed like a great product.I was using it in a 5.7 vortec tahoe i owned,and when you pulled the stick at 3,000 it was clean as could be as well as 4k,5k,6k and started changing at 7,000 mile interval and to my dismay was still clean. I know it is pricey however and I was recently reading a thread with test #'s about mpg improvements w/ royal purple so if money is not an issue you may want to search out some of those post and look at it as well.
