@Meria Mata generator ya sparta ilikataa ku start, nikaitaa fundi akadai ni spark plug na ni change oil ati ni chafu akadai thao for plug na oil na labour punch

apa ninachezwa ama nijibuyie mwenyewe ni wekee
Service mechanics hugonga serious,
Fanya hapa sample ya wasee huchajiwa how much for service na saa hizo ni oil filter, air filter na oil pekee zinakuwa changed. Akichange spark plugs bei inaongezeka. Ukiona wasee wanaongea story ya ku import their own parts jua wamechoka.

when pumping gas,does the meter amount you pay stop fuel at 1 or 2? if 1,is there fuel in 3? i've seen some pumps with the hose fitted up top therefore it's more of syphon effect and gravity ,but the pump above like one installed at sketchy fill up stations ,how does that work ama you lose few change,coz its almost a liter in the pipe
Far from it.
Before fuel is dispensed, the pump must fill up the hose (priming).
So in essence, the fuel present in the hose (from 1-3) belongs to the owner of the filling station.
Now to the science behind it:
Ideal liquids are incompressible (Fluid Flow topic). Therefore, the volume of fluid entering the hose at 1 must displace an equal volume at 3 (which is a loose description of the equation of continuity).
Thus you do not lose any fuel in the process.
[In retrospect, you must have thought of fuel dispensing as similar to draining a water pipe after disconnecting it from a pump. In case of filling stations, the pipe is never disconnected.]

However, while priming the hose, extra care is taken to ensure no air is trapped in it, because air (which is a gas) is compressible. This way, you will lose fuel. This is why there is a glass section either at the Nozzle IMG_20180113_095231_382.jpg
or at the base IMG_20180113_095144_389.jpg of the hose with two or three metal bearings to help us ensure that there isn't any trapped gas in the hose.
I hope your question has been answered.

Speaking of which I just realized I go for 500+km on full tank 2.4l engine.local running I never go beyond 80kmph and if I do only when overtaking... Is this good or bad.
