204.9 | LOW OCTANE FUEL! also first tank commuting at new place. Very short commute soon
to be replaced with bike when it stops raining. Fuel prices back down, and refilled with hi octane fuel. Although my engine has no detonation sensors, it hates low octane fuel1 | 22.90 |

205.9 | BEST 'Pure Commuting' tank EVER! 205.9 cents per litre. 4 cents per litre discount used. Pure commuting only. Temperatures falling, frosts in the morning are starting, usually in the low single figures in the mornings. | 31.35 |

0 | BEST EVER TANK!!! Test with 2x small rear wheel skirts (top 1/3 of wheel only), partial grille block (again, only 1/2 the grille). And massive coroplast airdam :) Got very good economy (4.0 units of petrol / distance unit on SuperMID versus the usual 3.7 I can get, if I am lucky, on long journeys. Journey was also suboptimal - steep hills doing 110km/h downhill and braking, and going out of torque convertor lockup when going up hill.
Also collected my manual transmission, driveshafts, starter motor etc, linkage, gearstick. Just need flywheel, clutch, clutch pedal and clutch master cylinder to complete the conversion kit :) | 35.12 |

194.9 | 194.9 cents per litre. Lots of commuting, one long journey (about 1/3 of tank total). Weather is getting colder, using more fuel on startup (and doing better hypermiling to keep MPGs high) | 32.03 |

0 | Again, SuperMID wasn't used for this tank, and again it was mostly
commuting / short journeys (4 mile journeys so mostly during the warmup
cycle). It is scary how close the last three tanks were (noting that I have
been driving using hypermiling knowledge). There really is a 'brick wall' that
this car cannot cross for short journeys.

169.9 | This tank had no SuperMID (I managed to break the network cable after much use + changing between cars!). I will get a new cable at the weekend (having found out that it is a 'straight through', NOT a 'crossover' cable for the record!). I would note no difference with or without SuperMID for this pure commuting tank. This is because the car is very 'unhypermileable' and if you accelerate to get the engine into a more efficient range, the torque convertor slips more, thereby wasting a higher % of the energy. Overall, the torque convertor seems 'perfectly' matched to prevent hypermiling opportunities. The only way to get better economy is to go at 80kph+, so the torque convertor engages. My current form of 'hypermiling' therefore involves trying to make each tank last as long as possible (in terms of number of days), something my e-bike will help with. | 24.50 |

174 | 173.9 cents per litre (oil prices went up suddenly). This tank has been pure commuting e.g. torque convertor almost never in lock-up, and with cold-starts most of the time. | 24.43 |

167.9 | Driving back up the North Island; it was getting late, I was tired, so I wasn't hypermiling that much, but, I found a new method of using the SuperMID like a wideband O2 sensor (based on my knowledge of Nissan ECUs from Bluey I). It *seems* to have improved my FE on cold-start town journeys but I will have to see what happens. Average speed was near 100km/h (speed limit is 100km/h), and the road is constantly changing elevation / direction, including random hairpin bends... | 31.69 |

168.9 | Driving down the North Island (NZ), and filling up about 30kms into the South Island. Rushing to catch the ferry so no 'extreme' hypermiling but still keeping an eye on the SuperMID. | 33.15 |

0 | Partly inaccurate. SuperMID needed recalibrating (due to me managing to corrupt the data in it). So drove around for a lot of the tank with one hand pressing the button to adjust the parameter from 32000 back to 7000, therefore no hypermiling. Also, only 7-mile cold-start commuting on this tank, and several full throttle accelerations. | 24.12 |
