Isn't this a Toyota design issue?
The range on my 1987 Toyota MR2 (with my SC engine) would be around 200 miles (on 9 gallons) under daily driving.
| Gauge Reading | Total Distance Travelled |
| Full -> Half | ~100 Miles |
| Half -> Quarter | ~180 Miles |
| Quarter -> Empty | 200 Miles or Ran out of fuel |
So it was weird because I could go 180 miles on 3/4 tank, but then on the remaining 1/4 tank, I would only get about another 10 or 20 miles and then I would be risking running it dry.
Same thing happens on my 1981 Toyota Hilux (using a 1991 V6 ExtraCab 18.4 Gallon tank and sender with 1981 Hilux guage):
| Gauge Reading | Total Distance Travelled |
| Needle Pegged --> Right on 'F' line | ~120 Miles |
| F-line --> Half Tank | ~160 Miles |
| Half --> 'E' line | ~220 Miles |
| E-line --> Bone Dry | ~260 Miles |
So my guage on my '81 will stay absolutely pegged way above Fuel Tank for 120 miles, every time. Then the gauge will drop like a rock to about half tank after an additional 40 miles or so.. Then it will stay around 1/4 gauge for quite a while and finally get to about 220, or an additional 60 miles when its on the E-line. Then I can still get a good 40 miles when the needle is well below the E-line.
On my MR2, I just figured that Toyota wanted it to drop quick when it was nearly empty to prevent people from trying to drive on an empty tank, which is a great idea because that will prolong the life of the fuel pump. But with the V6 tank, it is nearly the opposite, but that could just be that I am not using a V6 gauge, and despite the resistance being the same, the markings on the gauge will differ I'm sure
Interesting though.. It seems that every Toyota I've driven has a fuel gauge that reacts differently.
