I noticed that one time on this long drive, leaving a gas station, when I turned sharp out of the pump area to leave the lot, that the traction control light came on. I stopped, restarted and it went away. Then just today, I busted a Uie and the light came on again, this time the ABS, trac and trac control light all 3. Started thinking I'd need to get that checked by the stealer, then realized I had my ODI-II connector plugged in the whole time during the trip and today, and remembered reading about you guys mentioning that some of those connectors would cause the occasional light on the dash. I pulled it out, no big deal.
The mpg graph here on the forums, I still give a lot of credit to that chart. I've said it before that I'm surprised with its accuracy. I'll say it again, I think it is very accurate. I've seen a lot of those types of graphs on vehicle forums I've been on. But I don't think I've seen any as accurate as the one we have for the Mirage...
Coolant temperatures: One of the apps I have (Torque App I think) can read coolant temps. No matter the environmental conditions ... hot, cool, hot with the A.C. on, etc. As long as I was rolling down the interstate, that coolant temp was solid. It only varied between 192.8°F and maybe 195.0°F. Meaning, the cooling system if in good working order is very adequate for this vehicle. I wish I had watched those coolant temperatures when I towed the ATV a couple months back. That would have been interesting. I have to believe, it probably didn't get much warmer than the temps I just noted even while 'heavy hauling.'
A.C. mpg loss. I don't take these numbers lightly. I don't publish this with any intent to exaggerate. I used the A.C. maybe 20% of the time on this long trip. But I did use it in 1 strategic way in order to get a very good estimate of mpg delta. I estimate that
AT INTERSTATE CRUISE SPEEDS, using the A.C. reduces fuel mileage by ~4.5 mpg. I bolded the speed statement because I think that mpg delta will be less in more urban driving. Meaning, in downtown stop and go driving conditions, it may be only a 1 mpg difference. "City" driving maybe 1.5. And then "Suburban driving" like most of what I drive, it might be about 2.5 mpg lower with the A.C. It is when the A.C. is used at continual / steady loads that it maxes out the mpg delta. Honestly, it feels like my A.C. cycles on and off as I'm steady cruising the interstate. I don't know that because I can't stick my face down near the compressor while on the interstate. But that's what it sounds and feels like. There's no way in Chicago putting all 4 windows down will reduce mpg as much as the A.C. compressor. I don't care what a certain tv show said. Besides, I only roll down my 2 left side windows and leave the right sides closed. More comfortable that way.
