Gas for Ford V-10
Hello All, I am heading out for Yellowstone next Month and have a question for all the experts out there. I live in California and have 2 choices of fuel, 87 and 91 octane fuel, Last time I was goin...

Some useless and ignorable posts here, but TucsonJim gave some great info.
I wasn't clear that there is a difference between 85 octane fuel and E85 (E15). E85 is the high alcohol stuff you should avoid.
Auto Alliance and Global Automakers
The CRC study released today showed adverse results from E15 use in certain popular, high-volume models of cars. Problems included damaged valves and valve seats, which can lead to loss of compression and power, diminished vehicle performance, misfires, engine damage, as well as poor fuel economy and increased emissions.
"Clearly, many vehicles on the road today are at risk of harm from E15. The unknowns concern us greatly, since only a fraction of vehicles have been tested to determine their tolerance to E15," said Mitch Bainwol, president and CEO of Auto Alliance. "Automakers did not build these vehicles to handle the more corrosive E15 fuel. That's why we urged EPA to wait for the results of further testing."
The potential costs to consumers are significant. The most likely repair would be cylinder head replacement, which costs from $2,000 (to) $4,000 for single cylinder head engines and twice as much for V-type engines.
If you fill up with 85 octane at altitude, burn it off before you drive a lot of hills below 5000 ft. I understand the V10 runs a comp. ratio of 9.2:1 and would probably not be happy being loaded and heat soaked, driving uphill on a nice (and hot) California summer day. I suppose you could pour in some octane boost or top off with high octane to balance out your tank as well, then just keep filling with your normal fuel.
