[QUOTE="8WOOD, post: 1194791, member: 16395"] Regardless of fuel, the ecu will attempt to hit the advertised 450/510 numbers when at wot, but will pull back timing once it detects so many knock counts per unit time. If you are running 87 octane and the atmospheric conditions all favorable and no knock is detected, then you'll get max power. But it will be the limiting factor much faster than 91 and higher. If you are concerned about saving like 300-500 dollars a year in 87 to 91. Then use 87 and don't stress out the engine, and your engine will be fine. I personally wouldn't tow an 8000 lb trailer up a large hill at wot on 87 for an engine designed and tested to make 450/510 on premium fuel. [/QUOTE]
