Hi,


As title says, looking to buy a used Grand Voyager. But I'm not sure which engine should i get. Diesel or Petrol? I use car mostly every day to get to work.

Petrol engine is cheaper, but what about durability?? I know that Petrol engine is more powerful, but i want reliability over power.

Car is Grand Voyager stow n go 2008/2010

 

I'll have a 3.3 v6 any day petrol is cam chained with no known faults with engine I change oil every 3k as it suggests. My mate had the 2.5 td and within a month was leaking oil turned out to be oil seals in engine so engine and gearbox out and separated to replace seals costing over 1k.

 

A diesel will give you 30-33 mpg on a run. No idea what you'll get from a petrol.
The VM diesel engine is a good reliable engine, the bosch injection and fuel management system is well known and understood. Common problems on diesels are leaking fuel filters (sucking in air, though I think 08 might have the modified filter fitted) and the thermostat gets stuck open. Servicing costs on a diesel are usually a bit higher as well.

I'd go with a diesel any day, but that's because I run mine on veg oil or biodiesel and HMRC wont let us run petrol cars on ethanol.

Regards
Richard

 

I agree entirely with Tfb, especially if the motor is used every day. London taxis use a smaller version of this engine (2.5ltr.) The 2.8ltr. makes only 150horse so it is well understressed. This horsepower is commonly got out of 1.9ltr. diesels these days.
BTW, only assess your mpg. figure by the brim-brim vs. miles covered method, as computerized readouts are notoriously inaccurate. They work by counting the number of injection "squirts" plus the pulse length of the squirts over miles covered. As millions of squirts must be involved, the chance of inaccuracy is high.

Just a small addition -- because when a diesel engine of the current type (CRD) goes wrong in the fuel injection dept. it can run very expensive indeed. Each injector costs between £600 and £1000 to replace, and can only be done with dealer-only software as each one has to be "calibrated" by entering its unique number into the resident program in the ECM micro. by the mechanic's controlling laptop into the diagnostic socket.
There are alternatives, as usual -- you can get a piezoelectric injector cleaned and refurbed for £180, or so I read. Then you only have to be sure it goes back into its original hole. . . That all depends on how good the refurb. process is.
This means if you are spending say, £4G. to £5G. to buy the s/h motor in the first place, then it COULD mean the vehicle becomes an economic write-off if anything serious goes wrong with the piezoelectric diesel injection system. This raises an interesting situation.
People only really buy a diesel motor because of the much better mpg figure, esp. around town and stop-start driving. So it's actually an economic situation, although it looks like a fuel efficiency situation.
In the UK at least, you can buy fuel for a petrol motor at around HALF price in the form of LPG which is all propane in UK. So, economically speaking, if you can buy an already converted-to-LPG petrol motor at a similar price to its diesel version, you will avoid the ridiculous price of repairing the CRD injection system, should it go seriously wrong. In comparison, repairing petrol injection systems costs peanuts.
The let-down is of course the limited availability of LPG stations -- BUT -- you can always revert to petrol until you find an LPG station when in unfamiliar territory. So you won't be stranded at least.
This is a UK situation, because the government places much less tax on LPG. The CO2 emissions are around half that of petrol; the rest is water. I.e. less pollution. The situation in the US will be very different of course.
I understand the manufacturers are well aware of the costs of the piezoelectric injectors should they go wrong, and seem to be considering a return to the older solenoid injectors.
I've had an XJ6 running on LPG, and it was no problem at all. The cost-effective mpgUK was 40-44 on the motorway.

Luckily, the bosch injectors don't need coding to the ECU in the Chrysler.
CRD injectors are items of very precise engineering and it's hard to find a specialist who can test and refurb them properly. Mike (vrc8883 on here) did manage to find a decent specialist, though I cant remember where they were based.
