★ Top Answer
The 2007 GMC Yukon requires premium gasoline with a 91 octane rating. While it can technically run on 87 octane fuel, it is not advised because it can harm the engine over time. This vehicle is not compatible with diesel fuel at all. If diesel is accidentally added, do not attempt to start the engine as it will cause it to malfunction. It is important to act quickly in this situation by having the vehicle towed and drained immediately to prevent any damage.
