650miles in one tank

Hi guys,

I live in Australia, I just broke my prius record on reaching 1100km (680mile) in one tank. anyone here had even better result before?

I used to only get around 900km (560miles) however, since i have added acetone in the fuel (I use 98ron fuel in aus) the fuel economy improve quite alot.....

i am very happy with the fuel economy now, espeically in a time of high petrol prices ^_^

 

I have been using acetone for 3months now, i am very happy with it, I found the acetone does give better fuel economy, but it doesn't not have the same effect as my other car, mini cooper S.

The mini improved from 480km a tank to 580km a tank, and with the prius, i was averaging around 870km per tank if lucky 900km, however after acetone, i have been getting around 950+, and last week i broke my record and got 1100km.

 

I add around 100-110ml of acetone per full tank.....

i don't know how much is that in gallon

 

I use 98 octane fuel (BT or Shell)

I usually drive till the tank is pretty much empty...... then i go fill it up..... at once stage i filled my prius up for 50L, I know prius say its a 45L tank........ but i filled it up to the max top....

and i add around 100ml to my tank...... i used to put 120ml....... but i found 100ml give even more mileage.

also i pump my tire pressure to the High Speed recommeandation.

i don't drive on highway much....... once i drove a few hundred km @ around 110km/h.......... the fuel economy went up from 4.8l/100km to 5.6l/100km

 

I used to only able to fill 40L in my tank..... and the pump will automatcally stop....

i don't know the canda prius spec is..... but here is Aus, the prisu doesn't comes with a fuel tank flip, as in where the petrol bump hose go into the opening of the petrol tank, there isn't any metal flip part ......... so what i do is...... (during tuesday, when the petrol is cheapest in Sydney) I fill my car to the maxium top using the normal way........ then after the pump stop, i take out the petrol hose out of the tank opening...... so you can actually see the petrol flowing into the tank.... if you fill you tank slowly this way..... it will fill it up all the way to the top of the reserve tank......

I have tried driving the car nearly 70km after the light start to flash..... and i end up filling up 54L at the pump...... this is why i was able to do 1100km last month.... pretty cool.... don't need to visit the petrol station for 6-7weeks
