[Bullitt#0685]

OK, I see that people are finding fixes now for the pinging from 87 fuel. My solution as others was to simply use a higher rated octane. I just want know if the 92 octane I am using will eventually cause problems within my car.

Thanks all

Question Karl, What altitude are you at? and do they oxygenate (spike the gasoline with methanol) the fuel there in ID?

When I had 4165 in CO, in Denver, I could'nt run the winter (oxygenated) 87, I had to use 91. However, I could use the summer brew 87. I could run 85 any time in the mountains (they don't spike the fuel off of the front range).

Personally, I believe oxygenating the fuel drives the cost of gas up more than it reduces emissions. I was an emissions mechanic in Ft. Collins on college and ran many tests for my own edification when business was slow. The only time I saw emissions reduced was after a cold start, before the cats lit off. Granted, I was using just a tailpipe sniffer and not a dyno, but still...

My '89 2.5 Turbo/5spd. Le Baron kicked butt in the CO mountains. Bullitt did great as well. The only pinging problems I had were with the winter 87 down in Denver. I made the Denver-Aspen trip couple of times in the Bullitt before moving to FL that one starts at good 'ol 5280 , goes over a ~10.5K pass and through the Eisenhower tunnel at like ~11.5K. Ran great, on 85 even.

When I bought the Bullitt, my salesman said that he filled the tank up with Super (92 octane) so I filled her up with super for about a month. Read the manual and immediately switched to regular (87 octane). Nothing changed as far as performance and have not experienced any problems.

I get some spark knock at high RPM's in third and fourth on 87 octane. As 92 or 93 runs only about $2/tank more, I decided to just pay the piper.

I notice you have a low numbered Bullitt. The timing profile in the computer of early cars was slightly more agressive than later numbered cars. There was a TSB out about this and the dealer can reflash the computer to load the later version timiing profile. I have not had this done, I just run higher octane fuel to prevent detonation.

Thanks for the helpful tips. I have already had the reflash if that is what your referring to Peo'r. To be honest, I don't think that had any effect on my vehicle at all. Oh well, as long as it does not hurt anything I guess I'll keep buying the 92 stuff.
Thanks
