- Which engine?
Looking at getting a new car but not sure what engine is best to get ( petrol or diesel )
Most of the journeys are short trips 3 -5 mile. And quite frequent. Will do the odd 30-40 miler and an even rarer 100 miler. No more than 10,000 miles a year.
So what do you guys think.
It’s got to be 7 seater and the front runner is the kia carens 1.7 crdi 134 bhp

Modern diesels with DPFs hate short journeys but the car salesmen won’t tell you that.Posted 4 years agotheotherjonvSubscriber
depends also what the longer journey is. If a motorway run, so you can open it up and blow the crap out of the filter, that’s better than another hour at the same sort of low engine speeds as you’ve been doing all week.
This is my excuse for thrashing my diesel whenever possible. Better for it.Posted 4 years agospeed12Member
You don’t need to thrash a diesel to keep the DPF clean, and cruising along at relatively low revs (I.e. 70 in 6th) won’t be a problem. The ECU just needs steady driving at a reasonable load so it can manage the regeneration temperature. If the temp starts spiking due to big accels/decels then it will cancel the Regen (which is why town driving only will generally clog up a DPF). Running at higher engine speeds/loads (thrashing it…) will just give slightly more passive Regen – it will still need a steady period at low to medium load in order to do a full Regen.Posted 4 years agomolgripsSubscriber
On the Motorway you sit there at low revs for hours at a time which is not good.
You don’t need revs, you neex higher exhaust gas temperatures, which is dependent on engine load as well as revs. As speed12 says, if your engine is hot enough then the ECU will sort itself out – it needs some time to do a regen cycle – 20-30 mins maybe.
Plus booting it around probably causes more smoke to begin with. Sitting at 100mph for a while is probably good for it, but a bad idea for other reasons 🙂Posted 4 years ago
