I've just driven 502 km with my Starlet P8 and could only get 26 L in.. Needle was on the E line, but manual says it has a 40 L tank. So I reckon 600+ km is possible on a tank? 

CS is still on stock ECU so I guess 26 km on 50.2 L

Here's a question... what is the most economical speed to drive a GT-Four (or specifically a 205)? I know most people use 55mph as a rule of thumb for cars generally, but this is actually quite misleading as cars can vary greatly depending on engine size, gearing, rolling mass, transmission loss etc. as this image in Wikipedia illustrates... (the Celica being the 7A-FE laden american variant of the gen 6 presumably)



I am interested as this could make a lot of £££s difference on a long journey. Obviously, these cars are meant to be driven fast, but when you're on a particularly dull piece of road it's be nice to know if you're optimising your spondoolicks, as it were.
