Speaking from experience ama from the grapevine? You do know that most modern cars have tons of sensors... Additionally many modern cars are now Direct Injection. 6 years on, I've only had to change one sensor, and that was maybe 4 years ago. Just need to know where (not) to service it. Kama those guys that go experimenting with plugs... If I was to buy another Toyota saloon it would probably have a similar engine... ( e.g. the D4-S 2.5 and 3.0 V6 on the Lexus IS250, mark-X, royal crown etc) http://en.wikipedia.org/wiki/Toyota_GR_engine
Anyway - just my experience and choices.

Am glad ujinga ilikutoroka! The break pump is dead when engine id off and thus yu will need a massive foot power to apply the breaks effectively, handbrake is nothing for a moving car! lmaoest this reminds me of when i was a young and in-experienced driver. I was parking on a slope and the engine went off. Car started rolling downwards ... I still remember the SHOCK to my system as the more i stepped on the brakes, the harder they became. I was stopped by the pavement and got a scratched bumper for my struggles. Life is short. Live passionately.

Fuel gauge calibration is not linear. You are at half tank somewhere between the 1/2 and 3/4 marks

limanika wrote:@CLK, Interesting responses, do not just look at consumption…When filling the tank from empty to half, how much do you spend and compare this to how much you spend when filling from half to full? Answer that and also read https://autos.aol.com/article/gas-gauge/ then we talk… That article explains everything, that the fuel guage is only a rough guide on the amount of fuel in the tank, and that it is "rigged" to say different things depending on the volume of fuel in that tank, all with the aim of making the driver(consumer) feel good about his or her car's fuel consumption. Also, I think that as long as the engine burns the fuel at a certain rate, eg doing 15km/l which is about 7l/100km, and the rate is not related to the volume in the tank, it doesn't really matter whether your tank if full, half or nearly empty, or whether you refill at half or empty. The car will still burn the fuel at the same rate.

I have explained the Auto-shift in the most layman language, if you cant grasp it then please just drive and forget what happens in the bonnet. I think the driving school curriculum should be reviewed so that students are taught about the workings and operations of automatic cars since they comprise the majority of cars on our roads today. Also, I have always wondered why i normally see lots of relatively new cars being towed back to the city with damage that appears like they just went off the road and ended up in "shambas". The accidents could be caused by drivers switching off the automatic cars (to free wheel and on save fuel) without knowing it will make the cars uncontrollable.

My Experience. 1st leg you arrive with 1/2 tank 350Kms - Oksum citi or 500Kms MSA/Nrb
on return leg dont add fuel... Tank ampty after 200-250kms
my experience is with the car infront... siyui hiyzo zigine Take note of the space between floater (linked to fuel gauge and upper roof of the tank). The fuel stored there ndio hutudanganya. By the time you hit half tank, actually you have consumed 1/2 + ile space iko juu ya floater. I know some of you hupandisha one tyre kwa ramp to accommodate more fuel. @Punda, hapo uko na point. The car manufacturer never intended for us to fill the tank to the brim. When I calculate from F point upto the middle, I get 300 km approx. , and from the middle to when the light goes on is approx 200km, leaving me with about 100km of reserve tank. I believe same logic applies even when the read out is km of fuel remaining. They must find it difficult....... those who have taken authority as the truth, rather than truth as the authority. -G.

interesting and i think its true, from Nairobi to Gilgil the fuel gauge shows F, from gilgil to Nyahuru inafika 3/4.
from nyahururu to nairobi iko 1/4, this shows that from nairobi to nyahururu the vehicle consumes 1/4 but when back from nyahururu to nairobi the vehicles guzzles 1/2 Saitan!
