2006-03-02 334.9 6.31 53.07 "first tank with tires @ 48; mixed driving 50/50 hwy/city"
2006-04-12 399 6.58 60.64 "first tank using engine-off coasting technique (began part way thru tank) mixed driving"
2006-05-03 304.4 4.62 65.89 "Same mods/technique as prev. tank: lots of CODFISH; also streamlined wheel covers in addition to existing aero (rear wheel skirts, grille block). Occasional block heater use."
2006-06-08 275.1 3.64 75.58 "Piles of C.O.D.F.I.S.H, plus de-belted alternator for most of this tank. Mostly city driving (the fishing's better in town)."
2006-07-28 504.8 7.42 68.03 "Troublesome tank: wasted a bunch of gas during & troubleshooting a vacuum leak, testing the partial boattail, as well as testing the ""new"" transmission. Also, did a 200 km freeway trip which tends to drag my average down now (where it used to pull it up)."
2006-08-18 292.7 3.81 76.82 "What I thought was a fantastic record tank was in fact barely a record fill-up. I had mis-adjusted my slightly optimistic SG1 on the last tank (to report correct fuel usage - it was under reporting fuel volume consumed). Unfortunately, I adjusted in the wrong direction, so it was giving doubly optimistic readings until this fill-up. It's now correct. Alternator was on for the majority of this tank. Only other new mod was removal of passenger mirror at the tail end (so, no significant effect)."
2006-09-15 358.9 4.44 80.83 "A fair amount of P&G in this tank in the rural driving. Also a portion with the de-belted alternator (1/5 if I had to guess). 29 mph avg for the tank. SG is dialled in: it claimed 80.1 mpg."
2006-10-30 203.3 2.62 77.6 "- unbelted alternator for the whole distance - mostly city & rural P&G (avg speed: ) - I don't commute, so I never experience peak traffic (I live in a small city, so peak traffic is no big deal anyway) - I never have to start the car first thing in the cold, cold morning. Brr. - the roads I usually drive on are lightly travelled, and there's ample room for other cars to go by, or me to get out of the way, so I rarely if ever need to speed up to avoid being an obstruction. - 25 mph avg (last fill-up was 29)"
2006-11-28 557 7.95 70.06 "Includes a 200+ km freeway trip."
2007-03-21 534.6 9.05 59.07 "My ""winter"" tank! SG was way off. It reported 8.2 gal used, instead of the 9.05 actual. 22 mph avg speed - almost all sub/urban driving."
2007-04-29 396.3 4.7 84.32 "SG showed: 392 mi.; 27 mph avg.; 4.4 gal (US); 88.2 mpg (US) - So this tank it's optimistic by a whopping 4.6% (I never did adjust it from the previous tank. But I will for the current tank.)"
2007-05-31 383.5 4.76 80.57 "Lost SG tank data because I used it in my sister's Camry hybrid this week. I'm guessing my avg. speed was in the low/mid 30's mph though."
2007-07-19 267.5 2.57 104.09 "Just to see if I could do it: all P&G; avg speed 20 mph; all were real, legitimate trips (didn't displace any bicycle use either, which is obvious by the number of driven miles since my last fill); a faster avg speed than I would have been able to comfortably maintain over that distance on a bike; mix of sub/urban & rural routes.

My next fill will be significantly lower than this (highway trip coming up). "
2007-11-02 724.4 10.59 68.4 "Mostly highway driving (with load). SG tank data not saved. Since my tank only holds 40 L / 10.5 US gal, it may appear I played Russian roulette with the gas gauge, but in fact I topped up with a 5L short fill before the full 35L fill-up on the 26th."
2008-03-30 831.2 12.21 68.08 "Another winter tank bites the dust. Those with Metros will wonder how I put 12.2 gallons into a 10 gallon tank. I didn't - this fill includes a small splash 'n' dash I added a couple of weeks ago.

Can't comment on SG accuracy on this tank because I got the new SG2, which only has part of the tank's data."
2008-05-02 491.1 6.96 70.56 "I suspect the accuracy of the last fill was off (short fill), based on the numbers for this tank. SG showed 486 mi, 82.7 mpg, 29 mph avg, 5.88 gal used. This was with techniques that have normally gotten me those kinds of numbers.

Considering the last tank was my 'winter tank', and it was fairly high, this makes sense."
2008-08-17 678.2 8.46 80.17 "SG was reset (shared), so no tank data. This tank 100% highway driving, P&G for the first half, DWL for the 2nd. Alternator off for ~ 300 km at the end."

2008-11-16 474.6 6.33 74.98 "SG showed 468 mi., 49 mph avg; 70.2 mpg; 6.68 gal @ offset +3% gallons. Almost entirely DWL highway with a wicked tail wind. Can't vouch for fill accuracy though - full serve attendant. (Asked him to fill ""right to the top"", like I usually do, but can't be 100% sure he did. I'll sum it with the next fill (which I'll do) to get an overall accurate trip MPG."
2008-11-17 538.3 7.14 75.39 "SG showed: 491 mi; 45 mph avg; 69.7 mpg; 7.04 gal @ 0% offset. This was the 2nd half of my trip to the east coast, mostly driving with load (DWL), engine off coasting (EOC) down some hills, and some pulse & glide at lower speeds, where appropriate."

This ""tank"" is the pre Green Grand Prix top-up - short fill to 1st click (normally I fill to the brim, so this calculation will be off by 1-2 litres, approx, and will average out next time I refill to the brim).
