V6 fuel economy on long distance journey (lagos – abuja) – car talk – nigeria gas house dance hall


Last Saturday night, 27/11/2011, I filed my car’s fuel tank, Peugeot 605 V6. The tank takes 80 liters, which cost me N5,200 (five thousand, two hundred naira only). The next day, 28/11/2011, i drove off and headed Abuja. Before I got to Akure, i was expecting the fuel guage to be indicating low fuel level, but it was still indicating above half tank. I fired on and arrived Lokoja, after about 8 or 9 hrs high speed drive. The fuel guage was indicating 31 liters remaining in the tank. Hm! I was amazed! I fired on to Abuja from Lokoja, after mins of stopping at Lokoja. I arrived my house in Abuja about 2 hrs or so i drove off from Lokoja and the fuel guage was indicating 14 liters remaining in the fuel tank. I couldnt believe it! One full tank, in V6 car, on high speed, brought me from Lagos to Abuja. In fact, the car used only 68 or so liters from the 800km or so on the journey. It was unbelievable!

Whats the complain then about V6 running very thirsty? Am sure not all I4’s can run from Lagos to Abuja with N4500 fuel (70 liters). Am very sure that Lagos to Abuja is more than 800 km. Though, i know V6s can be thirsty when driven in the cities, but have better fuel economy than most I4’s i know off, on long distance.

There could be some I4s with the same or better fuel economy on highways. But you stand to gain more with V6. Why? With the good fuel economy of V6 on highways, you enjoy powerful performance or quickness of the car, most I4s wont give you. How do i mean? On my way to Abuja, i would meet a queue of vehicles following queue of 3 or 4 trucks behind, waiting for oncoming vehicles, still very far, to pass before they overtake, which takes eternity waiting. But whenever i reached such queues, I would bring the gear stick to gear 3, plant my foot little on the throttle pedal, off I went. It would zoom off or shoot like rocket. I would pass the queue in seconds & continued on my journey, while others behind would be waiting to get to straight road, without oncoming vehicle, before they could overtake the trucks. By then, i must have entered another state. I mean, it can be very fun, with the way V6 performs on highways. The speedometer, when accelerated, would behave or rises like the tachometer/rpm does. Damn! I love V6!

Most people hate long distance driving. But i have come to realise that the vehicle you drive for long distance determines if the journey will be boring or fun. If you take a boring car for a long distance driving, you will hate long distance driving. But if you take a fun, powerful & quick car for for that purpose, the hunger to travel everytime will become your new headache.

@ poster your right in your observations, 9ce one there. @ emperoh, your view abt european cars beta dan japanese cars is wrong cos japanese v6 cars hav beta fuel economy dan european v6 cars. Take 4 instance benz is an european made vehicle. Wud u tell me dat wen it comes 2 fuel economy its beta dan japanese cars lyk toyota, honda or even nissan. If those observations u made was abt benz, i’ll understand bt as 4 those cars u talked abt, i’ld say a big NO 2 dat cos i disagree wit u or may b those cars u used were d china spec. So i’ld conclude, @poster 10 ova 10, @emperor, go and do more homework.

You’re basing your opinion on emotion, you’re a Japmobile fan, so understandable. I have driven Japmobiles, Euro and American cars, and compare accordingly. I work on automobile on a daily basis. As for telling posters to do their homework, what exactly do you want them to do?

There’s nothing scientific, or remotely technical in your conclusion. You’ll need to drive different cars back to back to conclude. And Chinese-spec cars, where do you get that from? A Toyota Camry assembled in China will be built with Japanese CKD kits, same as US models. The fact it was assembled in China will have little, or no bearing on fuel consumption.

1. Speeding affects your fuel/gas mileage but not as much as you think. How fast you get up to speed (accelerate to get to your cursing speed) affects your gas mileage more. The secret is to be light on the gas pedal. But driving over 100 mph will burn more fuel because you need more power to overcome air resistance. Take a look at your RPM gauge that shows how much the engine is revved, you burn more fuel the higher the needle moves. Try to keep it below 2000 rpm when cruising.

3. High performance cars will usually use more fuel because of the design to get more horsepower out of the engine. There is no secret formula to generate power (air + fuel = fire/combustion) but the secret/knowledge becomes how well you can manage the exact time the combustion takes place (this is called “timing” and when you don’t get it right, your engine “knocks”) and what air-to-fuel ratio are you using which affect how “rich” or “lean” your car runs.

However, there’s a trade off in how you control all the parameters above and what the designer will do will depend on their goal. I left out compression of the engine, which relates to how much the engine is designed to compress (pressurize) fuel before it ignites. This is why some cars are designed to use higher rated octane than others. Higher rated octane will take a lot of pressure before it ignites but NOT cheaper fuel. When you use cheaper or bad fuel, the computers in the car will detect the knock and slowpoke timing (run less efficiently) to stop the engine from knocking which will make you consume more fuel.

4. Gearing. A Z06 Corvette gets 24 miles per gallon (9.8 L/100km) on the highway even though it has a 7.0L V8 that generates 505hp and 470ft-lbs because the last gear is designed for highway cruising, which means that at highway speeds, the RPM is very low (less than 2000).

In summary, you cannot just say a 6 cylinder consume less fuel than a 4 cylinder. Actually, with everything else being equal, a 4 cylinder will consume less fuel because the weight of the engine will be lower and you have two fewer cylinders to move.
