    I'd love to see you post this same statement again when petrol reaches RM5 a litre!

    No, diesel engines are not more efficient, their fuel is just cheaper. Both engines are still ruled by the laws of thermodynamics.

    I believe this advertisement is make up by the supplier of such device.

    As claimed by En Fauzan, Banting who drives a Toyota VIOS which is one of the most fuel economy 1.5 litre car in town. Even without the device, this car can easily clock 13.30 km/litre ( town driving) or 15.5 km/ litre ( Highway driving).

    Another car that is as fuel economy as VIOS is Honda City.

    Look at the calculation, 40 litre for 350km ( before fixing the device) or 8.75 km/litre. But after fixing the device, it clocks 450km/40 litre, or 11.25 km / litre.

    Do you believe what the advertisement claims?

    Why spend RM180 to buy such device which claims to be efficient in saving fuel. instead to spend it on petrol is a much better decision.

    you have to understand that advertisements do not include other details. like for instance the vios claims to clock some hundreds of km on just one tank. you see i'm a part time writer for some car magazines (more like i used to be). what they normally do on these tests (i'm not saying all....but most) they keep the speeds at 85-90km/h so as to keep the rpm at 2500. next, air condition is not turned on...they only open the vents as at that kind of speeds there's lots of air intake.

    having said that the 1.5L found in the vios is indeed a very good engine, one of the best 1.5's out there if not the best.

    for bigger cc cars like the bmw, bigger does not necessarily mean it will consume more petrol. it's because the car has more horsepower that the driver tends to be a little heavy footed. most cars like bmw,mercs etc...they're designed to keep comfort whilst keeping the fun in driving. it all depends on the engine mapping.

    diesel engines are a lot more cleaner and more efficient than they used to be. more often than not, the diesel engines have surpassed the petrol engines in many ways. problem is no one can tell me if our diesel here is as clean as the ones used overseas.

    using a high gear when you're below speeds is a very dangerous thing. you will lose traction and in the event of a slip, your car will have no grip.

    true fuel consumption is a very important subject now, i myself am complaining about the amount i spend on petrol every month. but price hikes are upon us whether we like it or not. so kudos to ski. well done mate!

    Actually, if I remember correctly, Diesel engine is like some 5% more efficient than Petrol engine. The reason why Petrol is so prevalent is because it has less harmful emissions.

    But recent developments of the Diesel engine have put them into premium marques such as the BMW 510d (did I get that right?). Moreover, diesels provide more power than their petrol counterparts of similar cubic capacity.

    Please correct me if I'm wrong

    which part of the car are you referring to as vents?

    cheers

    air vents. normally when the a/c is turned on, you will select the circulation option...the one where the arrow goes around the cabin.......basically the cooler option. the other option is to allow air from outside in without the use of the compressor and filter....hence direct air from outside......along with the smell ....fumes....

    I missed my old Kelisa GXi with 980cc DOHC EFi Engine
    the little buddy can clock 500km for a full tank for city driving
    Highway can get 600++km

    Now driving Kelisa SE, only can get 400++km for a full tank

    Without dusting off my old texts, I'd say off the top of my head that yeah, Diesel cycles are more efficient than Otto cycle IC engines but then, it's measured differently.

    By power you mean torque? Or output?

    I'm no expert, but all this is pretty subjective as there are many ways to disprove almost anything. You know what they say about arguing on the internet, even if you win, you're still retarded, so no offence meant. Don't want this to be a drawn out diesel vs. gasoline debate.

    What the original poster said was very true, as was some of the posts following said. Fuel economy begins with yourself. So when I see people driving hard on the streets of KL, I think to myself, "well, this guy sure is loaded, to burn fuel like that, when all he can achieve if perhaps a minute or two of time shaven off the transit."

    I know one friend who changed his engine from petrol to diesel, usj 27 you right you would need to change engine for this. But you must get JPJ approval for the engine change. and yes diesel is more efficient than petrol.

    Hehehehe D

    To answer your question, I dunno is it torque or output, but I know that why big vehicles like bus and lorry need diesels to move them, because the diesel engine gives more power...

    I think if fuel price increases to world market rates, we will be more mindful of the way we "tekan minyak" :P

    diesel engines have a much higher torque and pull.
