Hi, new here
Current forrester o4 owner considering trade up to new outback and wondering if its worth waiting for the new engine
if the consumption figures are 5.8 compared to 8.5 l per 100km and given that diesel remains at 10 to 15 cents more pl than petrol, are they likely to charge more for the diesel vehicle and would there be any fuel cost saving in the long run (say 10years ) and would service cost be higher, as you can tell i dont know much about diesel, or cars but you have to start somewhere:???:

Phil, take a breath, then insert a full stop somewhere.
Toofat, based on average prices for ULP and diesel over the last 12 months of $1.21 and $1.33 respectively, assuming a 10% premium for the new diesel engine, and driving 20,000km a year it would take just under 8 years to recoup the inital cost of the diesel.
Fuel cost for the diesel is 8c/km, 11c/km for the petrol.
I wouldn't expect servicing costs to be much different - they both have similar consumables, and modern diesels generally have the same service intervals as petrols.
Insurance compaines might be scared of the T word in association with Subaru.
Other considerations are the extra low-rpm torque typically provided by a diesel, and increased fuel tank range.

Work car is diesel... (VW Combi van) and diesel is way cheaper to run rather petrol.
If I had the chance, my next car would be diesel (yes Subaru) full stop.

I must respectfully disagree. Diesels are cheaper to fuel, all other things being equal. Total cost of ownership is entirely different.AlpineRaven wrote:Work car is diesel... (VW Combi van) and diesel is way cheaper to run rather petrol.
And I forgot to mention above that petrol engines tend to use substantially more fuel when loaded (luggage, roof racks, towing, hills, offroading, etc), where diesels do not. That should also factor into purchasing decisions.

its like that disclaimer for investment funds, past performance may not reflect future gains etc. Who knows how prices are gonna differ in the future.Some service costs on some Diesels can be staggering when it comes to the pumps and how far they gotta go before someone has the high tech service and diagnostic equipment (breathe) which costs heaps for the service guys to set up. I know a service specialist who favours Toyota Diesels having a great chuckle when a motoring journo turned pale at his $4000 bill on his Land Rover pump job and 'tune'. Trade up before it costs you and you'll be larfin'

Ain't that the truth !
Diesel injection systems are much higher pressure than petrol ones - the port fuel injected ones anyway .
Diesels can be VERY expensive engines to work on so I'd base he purchase decision on how fresh the vehicle/engine is .
I've known several people who sold out of diesel powered vehicles because the approaching major service bills get horrendous when the mileages get high .
Another thing is that late model diesels are growing an ever increasing number of electronic BS devices to rein in emissions output - this means expensive diagnostic equipment need to fix their minor and not so minor ills .
Your call , but if you think you are going to have a cheap to run diesel powered car for a long life think again .

oh yeah, and these high pressure common rail jobbies - get a little water or condensation build up from air in tank getting into the system - you gotta hope the water trap can handle it and can be emptied in time or the built in alert systems continue to work or you fit an aftermarket device ~ $600. Price an injector
for one of the latest common rails. I think when you see old Diesels with 400, 500,000 km you think gees that's good when compared to petrol cars of yeteryear but look at a Subaru of yesteryear and they get the same or better if looked after don't they? Petrol engines don't need spark plug replacement as often as once before, coil packs can still let you down and be pricey too, lead sets.... I wondered just how long LPG price benefit and wear on engines would be...twenty years ago. Still hate the SMELL of petrol so I stll go LPG. Horses for courses really, not a finite dollar decision.....

diesel cost effectiveness
Thanks for your replies,lots of food for thought, and useful info possibly no cheap lunchthen
so by the time 8 years are up and fuel savings kick in, service costs start to go up, trading up is not cheap either, 30 grand fom 04 forrester to current model via my local dealer.
I am only planning this because the rear seats in the forrester are really cramped and to take advantage of the government 50% tax break for small businesses buying new work related equipment.
I suppose its also possible that in 10 years time diesel electric hybrids or something similar will be the new cost effective vehicle to have
