I'm aware that driving habits play a huge role in economy, and this car frankly is very dependent I imagine on the drivers foot. The automatic in this car only has three speeds and it's a very "lazy and slippery" transmission, meaning that it shifts very quickly into top gear (around 17-19 mph) but in so doing can vary rpm from 2200-3500 depending on how you mash the gas pedal. Also, no tq lockup plays a big part I am thinking. Also, while I try to keep the car at slow speeds, because of the minute 790cc motor, I am usually unable to keep it below 3000 rpm, whereas my old Toyota could be kept completely under 1800 the entire time.
As for the oil, I am not sure. I imagine 15W-40 might be too thick, but honest to goodness, I have no manual and can't find one online either. Fuel that we have is pure gasoline, no ethanol. That's why it's almost $6.00 gallon here!
I guess I'll have to get used to it as I only have 50 horsepower now to play with.
EDIT: ^^Added a "Thanks" but I like mine better.
Also instrumentation would be great, as all I have is a temp, fuel and speedometer gauge. As you might imagine though, aftermarket gauges are a little hard to come by here.
