Does it really work and do you all recommend using it? If so, which brand would you recommended for a 2007 Yukon Denali? I'm a rookie when it comes to car maintenance and/or mechanics. I just always assumed this was a way for the oil companies to suck another $5 out of ya. But I just ordered my BB tune this morning and I figured I would do any maintenance things I can now while I wait for it to arrive.
