High-Altitude driving question

I have a '94 Wrangler ( 4-cyl, 2.5L, OBD-I, 130,000 miles ), and I am going to be driving it in Mexico next month at *extremely* high altitude (at least 13,000 feet, and maybe up to 15,000 feet).



Is there anything that I can or should do ahead of time to prepare the engine for high-altitude driving (other than the obvious stuff, like a clean air filter)? FWIW, I have also heard that Mexican gasoline is several points lower in octane rating than USA gasoline.



TIA, john w. ( jwallacq AT hotmail DOT com )

jwallace did pass the time by typing:

- The higher you go the less octane your engine will require.

- Never take a firearm or ammunition (even one bullet) into Mexico unless you want to spend many many years, in prison. They have zero sense of humor on the issue. Read this --->

- Check with the dealer to see if there is a high-altitude modification for your Jeep. In some cases there is a special CPS sensor that has been offset for higher altitude. Older Jeeps had a high-altitude wire but yours is probably too modern.

- Take spare parts, especially a fuel filter, and if you have them, belt and hose repair kit. Mexico isn't too bad for finding parts but your better off if you bring your own.
