So, here in Colorado (and a couple other states) the octane choices are 85/87/91. Some areas (not Colorado) have a mandate to put a warning sticker on the 85 pump that says use at your own risk-could damage your engine.
The manual says use 87. The gas cap says 87. The manufacture says explicitly use 87. Yet, most of us use 85. This is not a debate on using premium versus regular. I think I'm going to start using 87. The reasons 85 was allowed goes back to carburetor cars and the fuel industry has fought to keep it this way to avoid costly upgrades. There is no conclusive evidence one-way-or-the-other on of damage has occurred from using 85.
Does anyone in Colorado know what the dealerships use? I know they don't use premium (unless it's tuned). Do they use 85 even though the manufacture "forbids" it? Does anyone know for a fact?
