Real-world fuel consumption

Imported all data I have into SpritMonitor.

Click to see all fuel fillings.

I got also profile at Fuelly but they are not support imports, so no data for them :-p

Inside fuel filter

And the last one for today :-)
I made this video a year ago, but uploaded just now.

I was replacing fuel filter at 30.2kkm at home.
Workshop manual says to replace it at 60kkm. But as I got one already and it was interesting to see filtering element with Israel fuel - so I did it. And it was clean. I recommend to replace it at 45, at 60 top.

And some screenshots from "disassembly" video.

Xenum VX500

Happy to announce upcoming test of Xenum VX500.
2 boxes of 375 ml coming this Friday (each about 220 NIS).

Expected
- less fuel consumption
- better engine response on low RPM
- quieter engine sound

Stay tuned!

Update (2013-06-22)
Sorry, car was sold before testing this additive. But it will be used on next car.

Fuel consuption

I got today a trip from Netanya to Ashdod. I thought it would be nice to test cruise control (CSS) and see fuel consumption.

Speed was set around 100-105 km/h and the mission was to stay as long as possible with CSS on :-) You need to see road and predict what to do, it's like a game, it requires driving experience to "read" other drivers.

The results - driving from Netanya to Ashdod

Trip time: 0:56
Distance: 77.6 km
Fuel: 4.2 liters
Average speed: 82 km/h
Average fuel consumption: 5.4 liter per 100 km or 18.5 km per 1 liter

And the full trip with detour (5.1 km) to gas station (not on the way)

Trip time: 2:02
Distance: 160.3 km
Fuel: 9.4 liters
Average speed: 78 km/h
Average fuel consumption: 5.9 liter per 100 km or 16.9 km per 1 liter

The fuel cost of this trip is 81 NIS = 9.4 liters * 8.62 nis/liter (98 fuel ).

Multitronics full year 2011 statistics

This data gathered by Multitronics VG1031GPL (reminder, now on sale for few hundred NIS) since I installed it in later April till December 2011.

Overall stats
280 hours
12,000+ kilometers
average consumption 7.1 liters/100 km
average speed 41 km/h
827 liters of fuel

In traffic stats (when speed is below 20 km/h)
104 hours (4 days :-)
445 kilometers
average consumption 30.6 liters/100 km
average speed 4 km/h (like pedestrian)
136 liters of fuel wasted (3 full tanks or 1,000 NIS)

Real life consumption with Multitronics

Now, with new Multitronics VC731 getting trips data was never so easy. It saves last 21 trip and I can get all data in text file via USB. That's what I'm going to do once a month. No more pen and paper work.

All data is available in GDocs spreadsheet

Current avarages for last period:
Urban - 8.0 liters/100 km
Non-urban - 5.8 liters/100 km
Average - 7.4 liters/100 km
Driving notes:
- no air conditionning these days
- 1-2 people in a car

And here is official Skoda specs reminder

Old post about consumption - Real world fuel consumption.

UPDATE (2012-02-09):
A word about gear suggestions as noted in comments. Last few days I checked how I drive according to shift recommendation for changing gears on dashboard display. It turns out that I shift gears almost as computer suggests me :-) At least upwards.

Rattling noise is back

And now documented. Was fixed a while ago.





UPDATE:
Possible solution with foam rubber from friend with Seat Ibiza.

Real world fuel consumption

Skoda Fabia - Engine 1.2 l/77 kW TSI - EU5 screenshot from owners manual

According to this page from owners manual, our car should consume 6.8 liters at every 100 kilometers in the cities and 4.5 at highways. Probably, it is... in ideal world. Here in Israel with hot weather and different traffic I got other numbers, the real numbers.

https://docs.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0AstaR8Qp-BJZdFFoWTBmMUhBVTNhbGd6U254ZHRTc1E&single=true&gid=6&output=html
Urban - 7.5+
Non-urban - 5.8+

This is my on-going research. From time to time I check car display, Multitronics (that is very handy, it also log last 20 trips) and fill on paper and later posting in Google Spreadsheet. This takes almost zero time as I anyway wait a couple of seconds before switching off engine. Multitronics measures precisely enough, just imagine show me exact fuel amount I need to fill with difference of 0.1-0.3 liters.

Lower average speed indicates more urban traffic and also driven time. I also was trying 98 fuel to check if I got more power and less consumption with same driving style - that's not worked for me, I do not recommend to pay more and have same results.

Fuel gauge

Skoda Fabia's fuel gauge on dashboard

With help of Multitronics I was able to find what are these bricks mean in liters.

As we know from manual, full tank is 45 liters and last two is below 7 liters (low fuel turns on with beep). Using that and recordings I made, we have the rules:
- first one is 11 liters
- next big bricks each of 5 liters
- small ones before last two are ~1.5 liter each
- last two about 3 liters each

If you interested in precise numbers, go to GDocs spreadsheet.

Update (2013-03-28)
You can get exact results with VAG-COM while monitoring following values, but I have no time doing this ;-)
It also says how many graph bars to show on dashboard.

FullTank

Found today a new site for me - FullTank.
Here you can find where better to fill you car as by price and fuel quality. Here is full list of known stations with popularity indexes. Filters are fine, but main issue for me is that I can't sort by most important parameter - index :-( But you can do that in Excel or Google Spreadsheet with copy-paste (just make selection bit above and below the table) .

I have an idea to make a fuel station list with index above 50 for iGO navigation. That's also sounds good as I wanted to start coding Java - will be my homework.

FullTank Index depends on following:
1. Competitiveness - gas station that gives significant discounts on fuel, provides our customers with proper service benefits;
2. Convenience -  by examining the services and facilities at the station;
3. Fuel quality.

Google query for all places with "Quality Sign".

Prescribed types of fuel - unleaded petrol RON 98/95

Odometer: 2 630km.

Image source: Types of Fuel and Octane Ratings

I just figured out, that in Fabia and Roomster's SUPPLEMENT TO THE OWNER'S MANUAL Technical Changes 11/2010 prescribed fuel is 98!

Grades of petrol
Prescribed types of fuel - unleaded petrol RON 98/95 

Use unleaded petrol 98 RON. You can also use unleaded RON 95. However some loss of power is to be expected when doing so. 

If unleaded RON 98 or RON 95 is not available, you can refuel with unleaded RON 91 in an emergency. After refuelling, continue driving at medium engine speeds and minimum engine load. Driving at high engine speeds or heavy engine loads can lead to serious engine damage! Refuel with petrol with the specified octane number as often as possible. 

Fuel with a lower octane number than RON 91 must not be used even in an emergency.
Otherwise you can cause serious engine damage!

Have no idea what is it related to. Probably it's most for TSI engines and they afraid detonation issues. But who says that in Israel 98 is good enought? I tryed it twice (both from same station, but...) and I feel like 95 is better. Will be glad to find other feedbacks. I'll check that also in Skoda Garage on next visit.
