Honestly Ibiza all vehicles are originally tested with premium gas. Premium gas is just a cleaner gas than regular there are less deposits in premium as opposed to regular. All vehicles mpg rating is based on premium fuel consumption at a 91 octane as opposed to the standard 89 octane. So to answer your question, no premium fuel won't wreck your Yukon you may notice a jump in gas mileage, it won't be substantial but you will notice a slight increase, and you will also notice a bit of a horsepower boost. In the long haul if you switch the gas grade to much it will clogged ur injectors if you run just premium there will be less fuel deposits so less engine maintenance. I hope this was informative for you.

I run premium in everything. Except for my '03 S10. It's my beater truck. But my '08 Grand Marquis, '94 Cadillac, and '00 Grand Prix get premium. They only need regular but premium burns cleaner, hotter, and slower. This helps reduce deposits and gives better gas mileage. My '93 Caprice always got premium and during the 19 years and 120,000 miles I drove it I never ever had a fuel system problem or ever had to replace one sensor on it. HTH. -Jim
