Diesel fuel consumption?

Well, you give me hope for my TDI then, thnx :) I nurse my vehicle, idle before switch-off, use 50PPM diesel only, never rev her over 3000 Rpm... Original turbo still on yours?

Yeah, the TDi's can go for a very long time. As long as you service it when needed and as you do look after it, it will look after you for many many years.

I also let mine idle down before switching it off, very important to do this if you have been driving hard.

Yeah still has the original turbo.

If you are keen google Tdi club and go read some posts on there about Tdi's.

Was chatting to a guy on there who has 290 000 MILES on his Jetta Tdi with all the original items like turbo etc. Thats a whopping 460 000 KM +-. ;)

What actually happens to cars over 200k kms or so?

They get stolen before they reach that :D

Just remember that you can not slip when it comes to the services on diesel cars, if you do you have damage, period. The oil turns to sludge in the sump and that is extremely messy! Most diesel cars also needs to be serviced every 10000 kms AFIK

Yeah you can't leave a TDI like you can a petrol car.

Some diesel cars only need to be serviced every 15 000 like petrol cars.

The Landrover freelander 2 only needs to be serviced every 25 000Km's, basically once a year.

As I said, if you look after it, they can go forever.
 
I got a Hyundai i10(1.2) and was traveling 220km a day. Tank lasted me 3 days. 35 litre. Did around 5.5L/100 Km.Managed 680km on a tank
New i10 is more frugal think its listed at 4.7L/100Km so it should be around 5L/100Km.
Bought the car as I was a field techie in Gauteng really good buy. Wanted to go Diesel but just to expensive.
 
I think i worked out that the price difference between a normal golf 6 and the bluemotion would only be made up by diesel savings after aprox 80 000km of driving...
IS that really worth it?

Nah I wouldn't say so. . . I mean you are going to seriously save on fuel as is, I wouldn't nit pick at the l/km, the normal TDI does just fine.

My point is that the savings in fuel is not worth the extra cost of a diesel car. Ppl keep going on abiut consumption...but when the car costs that much more than the petrol, u need to do tons of mileage in order to 'save'

Thats cos the Freelander spends the rest of the year in the shop for repairs...

I have personally heard far more stories of modern diesels giving ***** than the few isolated instances where people get in excess of 500000 km.

Diesel reliability went out of the window with the advent of common rail technology. When a modern diesel engine eventually does go, ie injectors, turbo, dual mass flywheel, its gonna cost you an arm and a leg to fix.

There are so many things that can go wrong on a diesel nowadays, its not just the turbo that you have to worry about.

Hi

I drive 105kms to work every day and 105 back. About 75% of this is highway; 20% rural road and 5% city. I drive a 1.3 petrol Bantam. I use about 2 tanks of fuel a week. If I swop the 1.3 petrol Bantam for a 1.5 diesel version, or maybe a 1.7 Corsa diesel, diesel polo/renault/kruiwa etc, would there be a great improvement in my fuel consumption?

Also with diesel being more expensive than petrol, is it really worth it getting a diesel?

Don't look at the old Bantam 1.8 diesels, they are not very economical.

Having a bantam 1.6 myself I get about 600km (54l tank) with city driving. Your 1.3 seems to bit heavy but a few tips to get improve the figures. Keep revs under 3000rpm, skips gears like 2 and 4 if possible when gearing up, fit a tonneau cover over the load bin or remove the back flap of the load bin or keep the flap open (it really acts as a big airbrake), test filling up at different petrol stations and see where you get the best kilos per tank (shell extra 93 in Moreleta Park seems to give me more range than say the BP in Garsfontein).

Unfortunately I don't know what of type of pickup they used but I doubt it was a Bantam. Now when you have a tonneau cover on a Bantam the second half of the cover gets depressed heavily at speed from air coming over the cabin and pressing down on it, this indicates that the airflow will be hitting the flap if the cover wasn't there. I am sure the model and aerodinamics of it does affect the situation

Not true, the tonneau cover actually affects the creation of the low pressure area within the load bed and hence airflow will flow differently.

The area immediately behind the cab creates a nice low-pressure zone at speed. The rest of the load bed is low pressure as well, and at highway speeds, the 'stagnant' air in the bakkie bed creates a sort of "bubble" of immobile air. The incoming air stream over and around the cab "sees" this still air as a barrier, and largely flows right over it as if it were solid - reaping some of the proven benefits that you get if you have a solid bed cover. If the tailgate is down, this bubble of relatively still air doesn't get a chance to form, and the result is a less aerodynamic rear half of the bakkie.

A tonneau cover may help with fuel consumption, but it also might not due to the disruption of the low pressure area. Another point is that the difference with regards to fuel consumption between having the tailgate closed or open was rather minimal. Changing one's driving style is far more effective.
 
I'm no airflow expert so I wouldn't know if what you say is correct or not.

But you will notice I mentioned other things like keeping the revs in a certain range and skipping gears of possible.

Oh, I also forgot, overinflate your tyres a slight bit (instead of 210, says 250), improves fuel efficiency but can affect cornering and braking performance negatively.
 
Hi i drive a isuzu kb280 , 2000 model . i filled 40 litres of diesel inn, I only done 385 km?
 
I have a Vito 112 that shows smoke(Black) on acceleration and at times a slow power pickup :( but once up it runs like hell .
