Well I've run it in other vehicles with no issues, and my Cobra is supposed to take 93 but 91 is premium here, and it's been working fine also

I don't think it's that common, but it does happen

I think it happens more with the train going up Pikes Peak also since it's a steady climb and you don't get out to look around on the way up

ESP Come on everyone, we all know that you should just stay in your jeep when climbing Everest. Then the air problem is solved and your butt will be all comfy because you'll have heat. Swaaaeeeeeet!

tjt94 It always sucks when I go to Montana in the summer with the 85 octane fuel that is there. I have experienced pinging from the low octane fuel. I usually continue to by 87 octane anyway. It is still cheaper than the regular fuel we have in California.

I think the Bolivia episode is the best

Thats why it takes so long to climb everest. you have to get aclimated to the lack of oxygen...

baytownbert The air is so dense down here that a lot of mountain people have to get a back-pack mounted - air splitter to get rid of some of the extra oxygen, or they get giddy.

pprice72 The lower the air density the lower the cylinder pressures and at higher elevations there is less barametric pressure, sea level is 14.6 so at say 10K' you would be around 10psi +/-
You are fine with 85

dadrunamok Yup. When I moved to Maryland, I was surprised to see that the regular was rated at 87 octane. Growing up in Lakewood, I was used to seeing 85...

baytownbert You are good to go.

baytownbert 85 octane at what? 6000 feet elevation? 87 octane is the sea level rating. In other words, you are good to go.

Is the manual not smart enough to say 87 normally but 85 is OK at higher elevations (CO, UT, MT, etc..) or should you run 87 anyway?
