46 avg. mph. Two trips in cold rainy weather. One of those it locked itself out of Lean Burn and since car pooling I needed good heat and defrost, never got into LB the whole trip. Mid way through tank I pumped up the tires; they'd lost at least 10 lb. since last checked. Now at 52 psi cold so that's good. |

93 octane Shell, E. Htfd. station. The 3.6 gal diluted into the rest of the tank hopefully gave a net mix of about 89 octane which is what I expect to feed it. 87 octane gave persistent ping/knock no matter what I did, till ultimately I retarded the timing till there was NO get-up-and-go. That happened in this fill, which also had a lot of heavy a/c usage. |

93 octane. Blended into tank would make about 88.5 or 89 octane. Jackie kept hearing knock so I promised I'd use 89 octane. Set SG adj. back to about -10.x % following this fillup. First trip back home was via Rte 9 on a hot day, hardly any LB on Rte 9. Soon as I got to 95 in O.S. it was able to LB again. Hills + heat I think = no LB. |

Filled in a.m. in E. Htfd. Drove home from work with Peter, lots of engine off coast. ScanGauge showed 55 mpg. However nearly no Lean Burn on that commute leg so the ~43 mpg I achieved makes sense vs. the 55 on the adjusted SG. Short tank too, so it would have read 46.3 mpg if pump handle had clicked off .1 gal. earlier. |

89 octane in NJ on the way home from Phia. trip. Car had approx 30 mi. on the tank before we left and got out of PA before we needed gas. Jackie heard pinging which is why we got 89 octane. My theory was that ping was caused by hot intake air so I restored the oem configuration. |

Avg. speed tank, 46 mph. 2.5 legs (total 150 miles) with essentially no lean burn.
My theory is - it's due to the Shell gas I was buying, nitrogen-enriched. Messing up the HX's 3-way cat converter that processes NOx. No more Shell gas for me - let's see if that fixes it.
I had the engine temp up over 180 deg. F and intake temps were around 70-80 also. No issues there. |

Filled at E. Htfd. Shell, Main St. Warmer weather means more time in Lean Burn mode. If roads are wet, 32ºF seems to be the switching point. I've seen misting conditions around 32-40º where lean burn was limited to TPS mid 20's, not up to TPS 32º as with dry roads. |

ScanGauge failed twice: it reset mileage to zero. This entry is two small fillups I did, with a reset of tank clock to zero. First time, I spotted it and topped off within a couple miles to restart the tank counter. Second time, spotted immediately and topped off within about .4 miles. Both 'tanks' were full of short trips, one with heater running max heat. |

Interesting: Rarely would achieve lean burn this a.m. Then I reinstalled the grill block chunk I'd removed the previous afternoon due to running hot (192 or 197ºF). With grill block restored (right side of car), it went right into LB and stayed there. My theory is that the intake air warmed up as a result of restored block. |

Removed ScanGauge for warranty repair shortly before fill. Reason: most tanks suffered a data corruption whereby the full tank distance, gallons and mpg were not available at fill time. Display labels such as "MPG" or dFE would also corrupt and show some characters incorrectly.

One very short fill (.704 gal) combined with a regular fill. Had a check engine light - the old Cat converter code. Oil level was at half mark when I checked; my theory is oil burning fouled the cat. Just before the CEL it went out of lean burn and stayed. After that, after 1.5 commute trips, it went into LB no problem. |

Three commute legs plus two rehearsals. Two legs using true P&G with engine off coasts. One of those two, had the trunk open! Blame that on craziness from the home renovation fixit project. |

Return trip from NY, to/from work with Frank P. (fast), then back up again Wed. and fillup in a.m. in E. Hartford. After fillup I topped up the tire psi, should now be about 44/42 cold, front/rear. |

Trip to NY with Mike in car. He drove about 1/2 hour, did OK. Apparently the computer figured itself out by this time as mpg was very nice. |

Dunno why such low mpg. Entire "tank" was on new t'stat. Possibly the computer was still figuring things out. |

This 'tank' after noting that temp gauge was dipping seriously on coasting etc. This tank included minimal coasting in a futile effort to keep the engine temp up. Remedied just before this fillup by changing out the thermostat. Next tank is on new t'stat and new tires. |
