The 6.2 sounds like an awesome motor but the only SUVs that have it are the GMC Yukon Denali or the Escalade. I don't believe you can get it in the Suburban.
Unfortunately the 6.2 also requires premium fuel, right? That isn't chump change especially when gas prices go back up.
Yes premium fuel is recommended but I believe you can run standard grade with less performance and fuel economy. Not sure what the fuel economy difference is, but the improved fuel economy with the premium fuel could offset the additional costs?
