Changed from Petrol to Diesel. Stalling question.

disland

Hi

Changed from a Petrol to Diesel over the weekend and I stalled the car twice making right hand turns. Is this an indication of a problem with the car or that I am just not familiar enough yet with the diesel engine?

Is there much of a difference in terms of biting point of a petrol v diesel?

I changed from a 1.8 petrol to a 2.0 l diesel.

Cheers

If anything, the diesel should be harder to stall, having more torque at lower revs. Was the car stalling while in motion, or when starting from a stand still?

Should be harder to stall the diesel, but some models seem more prone to it than others.

Give it some time, you do need to get used to it. I say this as someone who thought a new petrol car had problems but it was just my lack of finesse on the clutch from years of driving diesels.

just make sure, you not putting petrol in to your car many people use to mix up, after car change.

does it stalls when you moving, or when you just start drive ? it may happen if you start drive, just need to get use to ... release clutch bit solver, i always feel, that petrol cars easier start drive, than diesels... maybe it is just me, but i getting diesels stall more often than petrols.

Agreed 100% you should be able to take off in 2nd or 3 rd gear in a diesel.

It has only happened so far from start drive making right turns. Im guessing its just coz Ive been driving a petrol for 8 years and im just breaking in the new car.

One thing I have found is that when the engine is cold/cool the diesels that I have driven can be easier to stall than when the engine is hot.
Perhaps that's just a "getting used to it" type of problem as well though.

That could be it alright. Ill be more mindful of it over the next few days and see how it goes.

It may be down to you not being used to the clutch pedal in a different car. I drive a car with 150000 miles on the clutch. I spend about 12 hours a week in it. When I go to drive a different car i find it takes time to get used to a new clutch bite point.

why not ? petrol driver use to rise revs up to 2 -3 k to move off... rev counter in diesel on same position is around at 1.5k .... and if release clutch so fast like in petrol car , youll get stall, to me it happens often on my wifes car (1.6 tdi), work jeep (3.0 tdi) and friends 1.9 tdi passat (not offten though) . i had never problems with other petrol cars.

opposite, my wife not stalling in diesel cars, but stalls in my petrol car nearly on every crossroad :pac: , ... so i assume, it is up to how you got use to the car... if not, regardless of engine type, youll get stall. ... not necessarily straight away, while youll keep in mind, that this is different car, youll be ok.

I found Diesels easier to stall than petrols (proper sized petrols anyhow). The torque at +1500 rpm is irrelevant as your are at 700-1000 RPM when pulling out from a junction. Thanks to the lagtastic nature of their power (ie nothing at all outside of turbo spike) and slow Rev climbing they tend to be "hoppy" and easy to cut out in that scenario.

A (NA) petrol on the other hand makes power immediately and revs climb fast.

Any of my daysul cars, have been able to take off without any throttle!
Cant say the same for the petrol ones.

(never had a petrol bigger than 1.6 though )

Old diesels were very difficult to stall, you could just come off the clutch and off it would go, but that all changed when direct injection came in. They'd sound like they're not labouring but within a millisecond of what you think is OK all of a sudden there'd be the violent thump of a modern diesel coming to a halt!
Large petrols are hard to stall on the other hand.

thats actually true, all depend, what size engine and how fast driver release clutch, you may start move petrol without touching accelerator,if you release really slowly ... .

But at the end of day, driver has to get use to car, if he changed a car, it will take a few days regular driving, to get use to throttle , engine power on different rev range and very important is clutch bite point. simple as that.
