AutoMoTech:
Where the gurus dey? Pls kindly answer this question. I am confused as to what to do as i have been faced with this challenge many times.

Whats the best thing to do when your fuel is low. When I have little fuel left in my car, is it better to drive fast or slow so that I can get the best distance out of the amount of petrol left?

Which driving gives you a higher chance of getting to your destination?

kingreign:


Slower, crawl speed, infact with car in gear 2 or higher, while crawling below 30km/h you'd go well. Don't allow rpm to go more than 1300

essenceplus:
Its two options. Test both, drivjg fast and driving low. Come back and give us feedback after you mist have tested it

FreshMekanik:
When you drive too fast you consume more fuel. When you drive too slow, you are not safe either. I did say balance your speed. 80-90 km/h

Davash222:
Low on fuel

Park your car, take a cab, go get fuel at any nearby fuel station and continue your journey!!!

jceesquare:
It depends on the car you drive and the transmission you have. So many things (like traffic, weight, and road conditions) needs to be placed into consideration.
Lemme give you 2 experiences I had sometimes ago.
1st experience was with a 3.3V6 auto gear. I wanted to take 4 clients from Ikeja to Badagry to inspect a water front property that was up for sale, so I went with my 2006 Toyota Sienna for the trip. I knew the fuel in the tank wouldn't be enough with the A/C on if I was aggressive with my driving so this is what I did. I reduced the fan speed of the A/C and was very easy on the gas pedal and allowed the car accelerate gradually from dead stop while making sure I never drove above 60MPH (we kept talking all through so they didn't notice the driving pattern). Another thing I did was being calculative with the brakes as well to save precious energy. I allowed the car coast from afar by taking my foot off the gas pedal when approaching busy bus stop or bad portion of the road before gently applying brakes. With that I was so shocked with the liters of fuel I had left when we made the return trip.
Scenario 2 with a 2.0 manual transmission (test purpose) I was driving back from Ilorin to Lagos and I had just ₦3,000 worth of fuel in my car Nissan Alrmera 2 door hatchback so this is what I did.
1st I rolled up the windows (to prevent aerodynamic drag) and turned on just the fan with the AC recycle vent open for fresh cool air ramming the radiator grill to come in the cabin.
2nd I was quick with my gear change and did upshift around 2,500RPM.
3rd I applied the coasting method and made sure I never exceeded 120kph except when descending from hill (I allow gravity do the speed up for me) so I can gain enough momentum to go uphill with gear 5.
With that I had enough fuel in my tank when I got to Lagos.
So driving light with as less weight as possible and being easy on the gas and brake helps a lot.

AutoMoTech:

Can you pls kindly explain the facts behind this. Engine load, fuel economy, ECU command, aerodynamics, drag etc

AutoMoTech:


Na weting we dey talk be dis. Based on experience. .. hehehe
So bro U sef dey enter ilorin wella?
Na ilorin i base on a norms bt currently in lag sha... we go sure meet up soon

kingreign:


Very simple, higher the RPM =more fuel consumption.
Higher gear= lower RPM.
Lower RPM= less fuel consumption.

jceesquare:

no problem faa.
I visit Tanke once in a while.

AutoMoTech:


So essentially you try to upshift to the highest gear faster while keeping your rpm low.
But engine, transmission and ECUs must be in perfect condition for this to work tho

kingreign:

It doesn't harm any drive train, in fact,its recommended

jceesquare:

Now you're going technical.
The driver needs to know his power curves to get the most out of his power train.
His driving pattern needs to work in tandem with his ECU for best fuel economy.
He needs to take as much loads as possible off the engine (high beam head light turned off, A/C off, defroster off, wiper set to intermittent speed if raining, radio and other electrical appliances turned off, tyre in the gauge, and so on and so forth).
Omo, that one no go easy ooO.

AutoMoTech:

I know it doesnt harm the drivetrain. What i meant was a car with a defective engine, transmission or major ECU will fail at that.

AutoMoTech:


If i had tested it i wouldnt be here asking for a discuss na broda. This is about sharing ideas and seeing how ppl think. Not about say na me kno book pass

essenceplus:



You dont get my twist logic here boss me. I also want to know and like you to be my testee

AutoMoTech:


Hahaha U r a bad himan being... hehehee
So na me be ur lab rat abi?

essenceplus:



As i never get money buy car baba, i need learn from your learning. And yes, me na bad person. mo gba

ichidodo:
My sweet spot is gear 4 at just btw 1500 and 1200 RPMs.

autologic:
The best way to save fuel is driving making use of deceleration mode of driving cos at deceleration ,ecu commands injector to cut supply of fuel .

AutoMoTech:


Shild of the world...
No worry bro. Your car is coming this year. believe it. And you will receive it

AutoMoTech:


I always tried this i was never able to achieve it. Pls kindly explain how you do it in an auto transmission

ichidodo:
That why Manny trans are so much better than auto tranny.....you get so much control and power. I am sorry its virtually impossible to do this with auto tyrannies.
