Another question. What would/could happen if I ran 85 and not 91? Here is why I ask. My company pays for my gas but only 85. If I don't use 85 then I pay 100% on my own. I drive about 18k a year, you do the math. I am willing to pay my way but wanted to ask if it really would hurt the car.

I wouldnt use the 85..this engine is high compression and calls for at least 91. I suspect if you use lower octane the car will retard timing..but I would still be worried about pinging/knocking
