diesel sedans

I don't think I would buy any vehicle with over 300kms. Because it is not just the engine that has gone that far.
Also Euro car parts are frightfully expensive, so if anything goes wrong it becomes a very costly exersise.
Then you have the problem of trying to find someone else gullable enough to buy it from you.

Forgot to add, another friend just ordered the Golf diesel with almost GTI specs, except for the engine. Looking at rechipping it, should really go with good economy.
Limited number coming in.

Sounds like a good car.

Reckons it is only just run in!> Why do people always say that? If it’s got 100,000k on it, the engine has been run in for a long time Diesel or petrol, with 100,000k it’s been run in for like 98,000 of that 100,000.

Exploder,

The reason is that at 100,000 kms a petrol is well worn, while a diesel is not, in fact if you ever have the chance to see both engines pulled apart side by side you'll see what I mean.
Petrol engines wear quicker not only because they are not as strong but the main reason is the fuel, and the residue it leaves behind as it burns.
Diesel is an oil and the combustion is so different that the rings, pistons etc don't wear at the same rate.

at 300,000 kms, a diesel cylinder will still have the honing marks visible, while the petrol has a lip on top of the cylinder, the cylinder would have ovalised and would be using a lot of oil.
Try to get the milage that buses and trucks get out of a diesel on a petrol...

true, but diesels are also built Heavy as they have higher comp rations, Higher combustion pressures and so on and that’s why the generally lasts longer and I am not saying they don’t, but people who say at 100,000k it’s only just run in Humm.. I don’t think so; I don’t think Detroit, MTU and so on bench run their engines for 1000Hrs before delivery.

Still seeing the Honing marks >agree but depends on how it’s been treated, if it had a hard life it can be glazed and have big mother Ring ridge at the top, taper and ovalety in the cylinder as well.

Petrol or Diesel you need to run it in from the word go, yes diesel will take a bit longer but not 100,000k.

I have always found that a new engine is run in (rings bedded in) when oil consumption drops to almost nothing between changes.

Didn't happen until my diesel pajero had 70,000k on the clock.

At 263,000, it is only just starting to use some oil between oil changes again. Half a litre per 5000k at the moment.

Not with new diesels< the Land rovers have like a 20,000k drain intervals I believe.

Good oil Combined with Good filters and even centrifugal filters as well.

The new diesel cars are 15-20k km servicing, and the citroen we are looking at is $3000 more than the petrol. The Peugeot is about $3500, but also has a 6 speed gear box, ESP and traction control.

If you look at 25,000km, diesel at $1.50, petrol at $1.35, diesel getting 6L/100km, petrol getting 8L/100km:
Diesel = $2250/year
Petrol = $2700/year

Resale should be about $2000 - $3000 more than a petrol, so when it is all added up, and a slightly increased serving interval is factored in, it is all about the same.

So in the first year you save $550 in fuel. At that rate it will take about 6 years to make up for the extra 3-3.5K purchase price. And then you need to factor in the increased service costs for a diesel over petrol. Yes the interval may be the same but the overall cost of servicing will be dearer.

Have to agree with WDR on this one. Only makes sense for very high mileage units.

I have been away sick from work so only just caught up on the forum. Are you saying that they are not reliable (your warranty comment) or just expensive to bet fixed (or both!).

ta,

Hi Gossy

We love our pug but it has been through two sets of front disk rotors in 18 months (they warp) and everything on the car is run by a computer, brakes, throttle, lights, wipers. The parts are no more expensive than jap cars, it is a myth that european parts are more expensive. The problem with euro cars are they are just to high tech and the finnish inside will just not last in aus.

Have fun
