Diesel-based 3.0 Engine vs Petrol-based 2.0 Engine

[arfandy]

Which one is cheaper in term of $$$ : distance;

 

Diesel-based 3.0l engine (Pajero Sport/Fortuner) or petrol-based 2.0l engine (Innova/Avansa/CR-V)?

 

I remember diesel is priced cheaper than petrol in Thailand. But also the size of engine determines how fast the car sinks the tank. Maybe some expert have any insight on this?

 

Situation:

 

If both cars (Pajero 3.0 and Innova 2.0) are filled with 1500 baht of diesel & petrol (let's say the cheapest petrol available in Thailand now).

Both cars run on highway from Bangkok to Pattaya at the speed of ~120kmh

Speed of both cars are reduced to city-limit when entering the city, maybe slight traffic, going around the city for half day then,

both cars return to Bangkok at the speed of ~120kmh in the evening.

Both cars have 7 passengers onboard, weighing ~500kg, no luggage.

 

Which car is likely emptying the tank before reaching Bangkok (or at least the amount of gas lesser than the other car)?

 

Thank you.

Dunno, but "you" can use Google to search all the stuff you are thinking about and come to your own conclusion...????

Diesels more expensive than petrol here unless u got an old car that cant use todays fuel.

What gear ratio's/final drive ratio and rolling diameter of the tyres?

[pgrahmm]

Too many variables to make an accurate assessment.....

My fil has a Hilux diesel truck 3.0 m/t + A Toyota sedan that probably has about a 2.0 gas engine - trans = not sure.....

He's proud about driving up from Suphan to CM in the sedan....He's tight fisted....

He told me 1700B to drive the truck & 1200B to drive the sedan.....Unsure about the rear axle ratio of the truck; but it's a heavily used/sprung farm vehicle - not a light duty toy, as some are....

For me, I like the heavier diesel vehicles with a tougher roadability given some of the unexpected perils lurking out there....

Here, we have 2 SUV's (diesel) & a Honda Civic....All run well but the Honda hasn't been driven for months....

Those are quite different vehicles, and old models at that. The newer 2.4 forthener gets good ecnomy, and so does the 1.9 diesel mu-x. The economy of the 2.0 crv was quite ordinary; not sure about innova. The advanza has a smaller engine, but its 4 speed auto gearing was not so good - well over 3000rpm at 100km/h.

But if you comare the 2.4 petrol crv vs the 1.6 diesel crv, the fuel economy of the diesel is much better, especially around town. The worst economy in the crv I even got (about 13 km/l), is much better than the average economy of my previous 2.0 civic (about 9km/l; 10km/l when it was new).

Diesels generally have better fuel economy than petrol motors, but they cost more to buy and cost a little more in maintainence.

My last 3lt Fortuner used to drink fuel. 12/3lt =100km if I was lucky. More if it was loaded and I put my foot down. But it was still better than my friends petrol 2lt Mazda (we did several runs together) The new 2.8lt Fortuner does about half of that. I get every time 6.1/2lt =100km, Even loaded. That's provided I don't go over 120kph and use economy setting in cruse control. A lot more in sports mode, and BKK traffic.

 

N/B the new 2.4lt Fortuner does a lot less fuel wise as it's geared down.

 

Someone mentioned servicing costs a 10th service cost me under 2.3th BHT inc: That's for 8lt of full syn: oil and filter and prop grease and that's at Toyota so not to bad. Sorry don't know what my friends Mazda used to cost service wise.

The average of my 2.4 l Pajero is 11.2l/100km when 70% is driving in the city. The best was 9.2l driving slowly outside the city (slowly means for me maximum 90 km/h). ????

Here's a Fortuner II comparison with 2 diesel variants and 1 petrol [2.4d (150 Hp) Automatic, 2.8d (177 Hp) 4WD Automatic, 2.7i (166 Hp) Automatic]:

What would it use if cannot use today's fuels....steam?

   Sorry, couldn't resist it...(but would still like to know).

PS, I have 2 cars ...a Fortuner and a Honda....the Honda is 27 years old...I used "91" in it and it drives like a ...Formula 1.

My 7 yr old Vigo, 3l diesel = 11 km / litre average.  GFs Honda City = 16!

I know which one I prefer to drive though.

What's wrong with that? My old classic Mini Cooper S would be pulling at least 4000 rpm at 60 mph.

I was driving a family Advenza in the PI.....

I was stopped at a light & was nudged in back just enough to notice it by a tricycle - who promptly spun a 180 and booked it going in the opposite direction.....

Didn't think much about it until I got out & looked = there was a 4" hole punched through the bumper facia and the bumper was loose, sagging/hanging down on the left 1/2.....

Not exactly the type of vehicle I'd want to be in in case of a real impact....

My ford 2.0L diesel goes 950KM on a tank.   But it is not a 4x4 model.  80 liter tank so about 11.9km/liter.

[br12stol]

Have a Civic Turbo 1.5 which has more power than the old 2.4 Accord/CRV motor, it has averaged 15.2 km per ltr over 18,000 km

Maybe you can find a Math teacher at the Japanese International school who will present it to the class to solve for extra points. ????

E85 and E 20 are considered as todays Petrol thought someones forgot to tell them in Northern Rural Towns.!.

2012 Mitsubishi Pajero Sport 2.5 (ปี 08-15) GT SUV AT to be exact VS 2012 Toyota Innova 2.0 (ปี 11-15) G Wagon AT.

 

I am not exactly keen with automobile, neither have any knowledge of whatnot. Hoping some car experts can share their point of views regarding gas-intake between the twos.

 

Thanks

I did but forum is still best way to ask for opinion. It seems like we both dont know the answer to my post, thankfully few others do.

Wish you would make up your mind. First off you asked for 3lt Diesel compared to 2lt petrol. Now your asking about 2.5mitsu/2lt G wagon.

 

If you care to look at the above posts you will see that a 2.5 Mitsu will do around the same as the old 3lt Tuna. That's around 12lt per 100km on a run. Innova around the same if not a bit more. Swings and roundabouts.

 

The only way you will get good economy is in the new cars The diesel ones will do a lot more MPG and the petrol ones can use the cheap petrol. The 1012 models you are asking about will use a lot more and be a lot more expensive to run.

Agree but you have to have an LPG tank filling the boot up, and the OP wants room for 7 people & luggage.

My old mini too (had about a 7K redline or so), but its not great for fuel economy. Before I modded my mini I would use 7.5L/100 km.

I apologize for confusion. I thought Pajero Sport only available at 3.0 and 3.2 engine but appearantly there are 2.4 engine too. But yes, those twos are the models to compare for efficency and forgive me as i have zero knowledge when it comes to automobile. I can drive safely but i dont even know how to replace the battery.

 

So you're saying 2012 models are quite diesel-inefficient?

Yeah, i need those space or else i'll just get myself affordable sedan-type with LPG-tank installed.

Absolutely nothing... but my Triumph Dolomite Sprint used to pull the birds at the Saturday night dances in Alford.

 

Then I switched to a Vauxhall VX4/90 FD and after a bit of initial reticence, they embraced the immense practicality of a column shift and the front bench seat.
