The manufacturer says in the owners manual that it's ok to use 87 octane but they recommend 89 octane. Personally I would like to know what their test results were (if they performed one) on both levels of octane. When a specific recommendation is made, I would like to know why. Especially when there are 2 options.

It may be ok to use 87 octane but if you get lower MPG then the cost savings may not be worth it.
