hi all, well i remember an old post asking this question.
well this week a guy i know who is older than me and looks after his cars & trucks. he had his Toyota van's petrol motor die on him with 400,000k started to make banging noises another guy i know has 480,000k on a toyota common rail diesel ute still runing nice never had to do anything never touched injectors, then there is another friend just hit 600,000 on a M benz sprinter Van 2.2 common rail diesel never had to touch injectors runs ok. 100,000k ago he was thinking of selling buying a new one but said he will keep this one as runing well. these three are all 4 cylinder motors so run in same rev range as the i30 CRDi & the i30 petrol. the petrol would probably need about 1,000 rev more than diesel to pull, plus uses timmed ignition. if you hear pinking that is like hitting your piston with a hammer.
but in most cases here people seem to sell there cars before they reach 100,000k. might be due to fashion? might be the need for more room, or change. those three motors i mentioned are all used for work, so do a lot of K's b4 replacing. so our motors get it much easier should last. with Diesel just buy from hi turn over outlets & only from the big oil co's. same with petrol but try to use 95 octain or better, that toyota that died @ 400,000 ran on E10, your motor should last longer on 95 , 98 ocatain as slower burning easier on bottom end keeps chamber and injection cleaner. just costs more than Diesel fuel.

well sort of a silly question really, no offence intended, I know a guy who has a sixty three year old petrol car and it's going along still as smooth as silk, check it out :-



Looks great to me

Off topic but



I wonder why it has an N plate, that would be illegal in the UK (to have a newer reg than the age of the car)

According to the DVLA, it was first registered as a UK vehicle on 01/12/1974 which gives it a "N" plate. Maybe it was imported...

[Dazzler]

Still off topic... Doesn't seem to work like that over here .. If someone sells their car and keeps their personalised plates then the car gets the latest current numbering system even if it is 20 years old..

Which can be a pain as I usually work out what year most Tassie cars are by the numer plate, if it is the original one.. (Bit of a mind game I play)

From the guys accent I would say that the car has spent some time in MERIKA ????  not sure tho

The length of a motor's life can not be determined easily. It is common for commercial vehicles to log up significant kms in it's lifetime. here a re a few factors that I know of :-

Cold starts & heating of the motor. Daily running of private vehicles requires a cold to hot cycle. Oil pools at the bottom of the engine, so lubrication is temporarily non existent till the pump pressurizes  the system. Commercial vehicles sometimes run all day so there are far less heat / cool cycles.

Long periods of inactivity. As above, but with even longer period of low oil & quite dry upper cylinder areas. This causes wear on start up.

Driving style, conservative driving while the engine warms up & not thrashing the engine will prolong life.

Petrol vs diesel, that's a difficult one, all I can say is that diesel is basically an oil. Petrol, although derived from oil is generally regarded as a solvent which works to dissolve oil. On that basis, I would say that upper cylinder wear is likely to be higher due to oil dilution and higher rotational speeds. Unburnt fuel can make it's way to the oil & begin dilution, which in turn can harm the whole engine. So my bet is that diesel, lasts longer.

A lot of cars are coming out with 5years/100,000kms warrantys. So a lot of people are trading in with warranty left on the car and getting a better trade in deal

And it could be that the car bodies are a bit shabby by then too. 

[diablo]

Car body shabby at 5 years / 100.000 km ?

My Renault Laguna was nearly immaculate at 12 years old and 85,000 miles. And I didn't look after it very well. Maybe Hyundais aren't made as well ? - I suppose I'll find out in three years time when it is 5 but still looks ok now.

I'm sure if you do lots of miles per year then the diesel is best and will last longer - the engines weigh vastly more than the petrol ones so maybe they should.

I only do a few thousand miles per year and not many long trips so petrol for me. Don't want a particulate filter to clog up at huge cost thank you. Horses for courses etc. . . . .

There are plenty of taxi cabs out there that have over 500,000 km on the odometer.  The reason is, as 84 stated, that they run constantly, therefore don't have the hot/cold cycles which is where most of the wear occurs.

Even with our gas turbine engines (in helicopters running on AVTUR) we count start cycles as a life limiter.  If we don't want to wear the engine out, we keep it running.

It's actually not too bad, I think it's only around 40 kg....

I can't reply to the petrol versus diesel arguement, because the i30 I have just purchased is my first Diesel passenger car. However, the deal was to trade my 2000 Subaru Outback that had 397,000kms on the clock!!

There was nothing wrong with the engine. The suspension needed a tidy up, but otherwise it was in good condition. In fact the dealer was blown away when I told him the kms, considering the condition of the car. Also, the heads have never been off the block.

The moral of the story...... I changed the oil every 10,000kms, religiously. I always used the same oil and every oil change all the filters were done at the same time. I did go through 3 clutches, 7 sets of tyres and two CV joints, but I think I got a pretty good run out of the old Subie!!

well sort of a silly question really, no offence intended, I know a guy who has a sixty three year old petrol car and it's going along still as smooth as silk, check it out :-



Looks great to me 

Beautifull in much better shape than me! LOL
I have a friend with an old Roll's too But its Huge not sure what year but was used as ambulance in one of the world wars. he has changed it back to original. have not seen it for a while but has a big motor uses that much fuel would not beleave.
not sure if it leaks oil, but if it don't leak oil it would be the first old Brit Car or bike i've seen that don't leak oil. LOL

There is no reason why you can't get the same run out of the i30 (and you will use far less fuel)

The Rolls' and Bentley's' are OK and apparently, if you drive very, very carfully you can achieve ......






ten, yes that's right, ten miles to the gallon.  That will be UK gallons of course

If you can afford to buy one I guess the fuel bill is irrelevant. I wonder actually whether RR spend much on efficiency and pollution control. How would they meet current international emission standards. 

AFAIK GM & Ford can't sell in China 'cos their too dirty.

I'm same age as that Roll's LOL.
when i was younger i had High Performance V8's that had Carb's, fuel was that cheap we did not even know how much per Imperial Gallion it was. but i think with the HO phrase 3 i was only getting around 8 MPG in city was a bit better in country. had a 36 gallion tank. we never had a maxium speed limit in those days. so drove fast in country.
motors in those days did not last that long 4 cylinder petrols did not last like they do today. oil was poor quality. metalurgy was not as good.

[Lakes]

But Roll's Built to last in those Day's. i was told by an old timmer, Roll's burried there heads for a??? length of time to to put under stress them bring up & machine. so they had bullit proof motors. economy in those day's was not a worry. know one worried about imissions eather cars did not have air conditioning or power steering. weather in Australia was just as hot as today. no seatbelts
