Exceeded 750 km on one tank

The challenge to better the One Tank 750 km mileage was first conceived on May 7, 2015.

You can read more here at my initial attempt.

============================================
Vehicle setup

Stock setup - Honda Stream RN6 - Compact MPV
Similar engine to some Honda Civic: R18A - 1.8 L Auto
Motor Oil:  Shell Helix 5w-40
Fuel: Caltex 92
Tire: Goodyear Triple Max, Pressure between 32 to 36 PSI
============================================

Finally on Sep 24, 2015, I succeeded with 753 km.

What is more impressive was the low fuel lamp lit up at 732.8 km compared to the previous tank at 642.2 km.

The tire pressure at end was 227 kPa (32.9 Psi) and it was not maintained at my usual 245 kPa (36 Psi) for some time.

Here is a series of dashboard shots of distance vs fuel level






Finally the 750 km mark





Here is the 14.1 kpl average on 8,768.7 km accumulated so far.

This is a comparison to the similar engine type sedan (Honda Civic 1.8)

The difference is the body profile and weight.

Kerb weight Civic (Sedan) vs Stream (Compact MPV)
2600 lbs (1179 kg) vs 3020 lbs (1370 kg)

Not bad for a compact MPV to be driven efficiently to be placed in the same 14 kpl range as the sedan cousins.

2nd Tank

Here are the second set of results of the fuel usage after cleaning the Air-Fuel sensor.
The first tank yielded 671 km on 51 ltr of fuel. 

============================================
Vehicle setup

Stock setup - Honda Stream RN6 - Compact MPV
Similar engine to some Honda Civic: R18A - 1.8 L Auto
Motor Oil:  Shell Helix 5w-40
Fuel: Caltex 92
Tire: Goodyear Triple Max, Pressure between 32 to 36 PSI
============================================

On this second tank, the car yielded 683.5 km on 48.086 ltr of fuel.

To compare more accurately, the data from the Low Fuel Lamp will be used as the total distance can be stretched till the tank is really empty.

On 1st tank, the LFL litted up at 646.7 km
Today's tank, the LFL litted up at 642.4 km

Hence i can say that the consumption has been quite constant for these 2 tanks after cleaning the Air-Fuel sensor, which gave the engine better fuel economy.




My previous results 


This is the photo of the 2 sensors. On the left is the post Catalytic convertor Oxygen sensor.
On the right is the pre-cat Air-Fuel sensor.

As you can see, the Oxygen sensor face is rather clean since it is far away from the exhaust manifolds and sees little additive contamination when compared to the Air-Fuel sensor.

Condition of Oxygen sensor & Air Fuel sensor at end of 2nd tank
This is all made possible by the very cheap and sturdy sensor socket i ordered from Ebay.
US$5 China made 1/2 inch sensor socket. Very solid construction. Price includes postage. Cool!
