I guess I'm one of the only ones that will run 87 octane back and forth to work when I'm not pushing it. I let the computer do the work. I put 91 octane in when we made the run to Mt Evans at 14,000 ft. or I'm running it hard. I filled it back up, put 9.7 gal and ran 273 miles, you figure it out. I have 17,000 miles on it and seems to run fine. I know later a new engine??? Can anybody give me any stats that show where engines are being replaced because of lower octane?? I'm not talking about all you race car drivers out there... You'll replace an engine just because you run them hard and don't tearem down like you should.

Now you can beat me up, come on I'm ready for yah I just hope you've got 91 in your tank.... lol
