The test was for 47.3 Km in hard City traffic conditions, in purpose quickly left the boulevard and engaged in traffic like a taxi driver, right lane, no overtakes, behind buses, waiting in bus stop etc.
i wanted to see the car's behaviour now with the modified air filter box, now more air comes inside and has no restriction till the throttle.
Last Sping when i had that damned-crappy 15W-50 the Fuel Consumption in such conditions was 12.9ltr/100Km (21.90 Uk MPG) and the worst was one night at 13.1ltr/100Km (21.56 Uk MPG).
Now i have that tremendous Synthetic 10W-40, full repaired suspension, modified air filter box, 98 octane gasoline from different gas station than last year and the result in that ''torture" test was:
This is the Average Fuel Consumption, 11.1ltr / 100Km or 25.45 Uk MPG
This is the Total Fuel Consumption, the car burned 5.1 ltr gasoline for 47.3 Km distance or 10.78ltr / 100Km or 26.20 Uk MPG.
I wish i could do more Km distance but it was noon, the sun was high, i was in sweat and i didn't want to open the a/c because i wanted to have similar situation with last year test.
As for the difference between the 11,1 and the 10.78 i have to say that in Average function (with the ⌀ symbol) the TC-6 does not react so fast, takes time to make a change for more or less.
In the Total with the Σ symbol (from the Greek word Συνολικη) is more accurate after a calibration and i have checked this 2 times in previous FC tests so i rely more in this function.
Nevertheless the results are amazing (for my modified and heavy that stock car), keep in mind that some years back i had 14.7 ltr or 19.21 Uk MPg and take a look now, i have made a huge improvement and Yes, i don't regret even for a second that i have cut the engine cover and modified the air filter box, it worked !
