You said what I was trying to say. My car is meant to run on 91Octane. As other have said and posted, running premium in a car designed to run on lower octane serves no purpose.
In addition to this forum, I also frequent a "car blog", and I can tell you that at least 2/3 of the questions that people ask about their cars are actually very basic issues that are clearly addressed by the Owner's Manual.
Many of the repair problems that people experience as their cars age are the result of not following the manufacturer's maintenance schedule that is contained either in the Owner's Manual or in a separate booklet provided by the manufacturer.
Also, many people ask questions about the terms of their warranty coverage when that information is also contained in either the Owner's Manual or in a separate booklet with an appropriate title.
All of this leads to the question of why it is so difficult for people to open the glove compartment, take out a booklet (or two), and do a bit of reading. One person, after being advised to refer to her Owner's Manual, responded with a scathing reply to the effect of, "Why would I read something technical that was not written so that the average person could comprehend it?" In reality, car Owner's Manuals are written on, at most, an 8th grade reading level, and the only communication problem related to those manuals is the apparent difficulty in getting people to actually open them and read them.
So, just like the issue of the appropriate octane for one's car, virtually every other issue related to the safe and economical operation of a car can be found in booklets that are sitting in the car's glove compartment. However, I am dumbfounded by how few people actually take the time to consult these easily comprehended booklets. I guess that it is just one more example of the lack of personal responsibility that is so rampant in society today.
But, to return to the issue of octane, many people spend needless money on premium gas even though their Owner's Manual clearly advises the use of regular gas. They have a mistaken idea that using higher octane gas will give them more power, or that it will keep their engine cleaner. And, conversely, there are also people who wind up with engine damage because they operated their car on regular gas, despite warnings in the Owner's Manual that only premium gas should be used. These are classic examples of added expense that could have been avoided simply by reading the materials provided by the car's manufacturer.
